How to open the Philips TV remote control. We repair the remote control

We can describe, as an example, many cases due to which a television control panel will have to be repaired, but they are united by one factor: first, the device will have to be disassembled, and this is not so easy to do. Many remote control models are assembled without the use of bolts, so the biggest problem in the disassembly process can be considered the search for connecting elements.

Let's figure out step by step how to open the LG TV remote control so as not to damage its case and, most importantly, the microcircuit, because in this case it will completely refuse to function and you will have to buy a new one.

Remote controller lg how to disassemble: step by step guide

Step #1:

The first thing you need to do is remove the batteries from the remote control; this is not difficult to do; you can find them under the back cover of the device. Under the cover you can find screws that need to be removed. For this purpose you need to use a small screwdriver. After this, you can try to separate the two halves of the body from each other. Depending on the specific model of the control panel, the method for removing the cover may also differ; in some cases, it is enough to slide it up and it will open; for others, read the next step.

Step #2:

Useful if there are no screws on the LG TV remote at all. In this case, parts of the case are attached to latches, when opening which you must be as careful as possible. I’ll say right away that you can’t exactly do this process by hand; you’ll have to use a special tool. A rounded, dull knife, preferably plastic, will work as such a tool; the metal can damage both the control panel body itself and the latches, that is, it will no longer be possible to close it in the future.

This is interesting: Service center technicians open complex models of control panel housings using a coin, but such manipulations require skill and experience.

Step #3:

It seems we have figured out how to disassemble the LG TV remote control, the next step is to get the device chip. Usually this part of the remote control is not fixed in any way, only fixed in special grooves, so the circuit can simply be removed from them. The most important thing is not to place the microcircuit on a hard or even dirty surface, this can harm it; it is best to lay a specially prepared cloth to avoid unpleasant consequences.

TV remote control repair lg with your own hands

The majority of malfunctions in the operation of the remote control are associated with user inattention; a spilled drink on the device, for example, can disrupt the operation of the microcircuit. In such a situation, cleaning the circuit with an alcohol solution can help.

The best solution would be to contact the LG Service Center, where they will most accurately diagnose the problem and fix the problem.

In order to clean the control panel microcircuit you will need to perform several simple manipulations:

To begin, disassemble the remote control, following the tips from the beginning of this review, place the device chip on a safe surface, removing it from the case and separating the rubber part with the buttons. The next step is the cleaning itself. For this purpose, take pure alcohol or a liquid with a significant content of it. Using a clean cloth, wipe the circuit with alcohol and dry thoroughly.

Now you can put the device back together and check it, everything should function properly. Sometimes intervention on your own can only cause harm, so if you are not confident in your abilities, immediately contact a specialized service workshop.

The most common defect unintentionally incorporated into the design by remote control manufacturers is (judging by personal practice of repairing remote control) poor contact of the “positive” and “negative” terminals with the power supply. Made from an alloy that is not entirely suitable for such devices, they bend easily and lose their former elasticity during operation (especially after the warranty period has expired). Damage to the springiness of these terminals can be eliminated quickly and permanently by placing soft rubber (for example, an eraser) between them and the end of the board, which will reliably press the contacts to the batteries.

The second most common defect in the remote control is the deterioration of contact between the graphite printed elements of the board and the conductive rubber pressed against them by the control buttons. The reason is fat trapped between the buttons and contacts of the board, a decrease in the quality of the rubber itself, from which after 2 - 3 years of operation an oil-like substance is released as a result of a chemical reaction. By covering the printed circuit board, it interferes with the contacts.

Another common malfunction is when the most commonly used buttons stop working, or work, but only when pressed hard. This wears out the conductive coating of the rubber base contacts. The rubber contacts under the buttons physically wear out, losing conductivity. The graphite elements of the printed circuit board are also subject to wear. In such cases, you need to replace the rubber with buttons with new ones (they are sold on radio markets). This repair kit consists of small conductive circles and glue, which you will need to glue on top of old, worn conductive rubber-based contacts.

And the printed circuit board must be carefully cleaned of the viscous liquid released with a dry soft cloth. Graphite contacts can be easily restored using a soft pencil.

Attention!!! Contrary to the common practice among radio amateurs, under no circumstances should you wipe the graphite contacts on a printed circuit board with alcohol, cologne (and especially solvents). Graphite is destroyed by alcohol-containing substances and solvents.

You can make sure that the remote control board is working as follows. Having assembled the remote control in the case, do not rush to place the rubber mat with buttons in its designated place. But the power source should be inserted. Then, using a mini-pointer twisted from foil, you need to alternately (through the holes for the buttons) touch all the graphite contacts on the printed circuit board.

If the TV responds normally to commands from the remote control, then the board of the remote control is working, and only the rubber with the buttons needs to be changed.

If there is no reaction, then the cause of the remote control failure may be the desoldering of infrared emitters, capacitors, or microcracks on the board itself as a result of falls and impacts.

It happens that you can’t buy new tires. However, you shouldn’t despair - you need to restore the old one. It is necessary to separate the black contact plates from all the buttons on the back of the rubber mat. Then use any rubber glue to glue new ones onto the vacated spaces. You can find functional contact plates in many old electronic devices that are considered unsuitable for other reasons: calculators, push-button telephones, etc.

Contact plates made of conductive rubber are carefully removed, cut with a sharp blade or scalpel to the required diameter and then glued onto the rubber mat of the remote control. Considering that the “donor” plates can have different dimensions, the excess is cut off from them with a blade, ensuring that the thickness of the plates does not exceed 1 mm (otherwise the remote control buttons will be constantly “pressed”).

Restoring remote controls

How to disassemble the remote control

First, you need to disassemble the remote control. Despite their different sizes and appearance, all remote controls are essentially the same.

We take out the batteries and at the same time look in the battery compartment for the mounting screws, which may be located under the factory stickers. Use a screwdriver to press down on the sticker; if it pushes through, it means there is a screw underneath it.

Modern remote controls may not have screws at all. In this case, you can proceed immediately to disassembling the remote control.

The remote control body consists of two halves, connected to each other either with screws, or with latches, or using both methods. To separate the halves of the remote control, a suitable tool, for example a knife, is inserted into the connecting seam. We carefully insert the tip of the knife into the gap between the halves of the case and try to push them apart until a click appears. Some descriptions of this procedure say that the screwdriver may leave marks in the form of chips and scratches. Therefore, it is safer in this regard to use an old or unnecessary credit or discount plastic card, which are issued in unlimited quantities in any supermarkets or most branded stores.

A click indicates that one of the latches has opened. The main thing is to successfully get to the first latch, and then gradually open the rest. Try to do everything carefully so as not to break the latches, and even if you break one or two, it doesn’t matter, it won’t make the remote control close any worse: checked. You can also separate it with two thin screwdrivers, or combine a knife and a screwdriver, as you wish.

If you are disassembling the remote control for the first time, it is preferable to use a knife and a screwdriver. First, insert the tip of the screwdriver into the gap between the halves of the case and, slowly moving the screwdriver along the case, look for the first latch. As soon as you find it, you snap it off, but leave the screwdriver stuck near the latch, and then continue to work with the tip of the knife. When you reach the next latch with your knife, you can insert a second screwdriver and continue moving with the tip of the knife, or continue moving with the first screwdriver. In a word, do what is most convenient for you.

When, for example, the left half has opened slightly, carefully, without removing the knife, move it along the body, unlatching the latches, until the remote control is completely opened. Carefully remove the board and rubber base with buttons. Pay attention to the battery compartment. There are grooves into which the spring contacts are inserted, so before you pull out the board, remember how they fit in the grooves so that there are no questions during assembly.

Step-by-step identification of the cause of the remote control malfunction and its repair

If you carefully look at the board from the side of the tracks and at the rubber base from the side of the contacts, you can see that in some places they seem to be smeared with a thick layer of adhesive mass. This is fat. Because of this fatty layer, there is poor contact between the graphic coating of the board and the contacts of the rubber base, which is why we have to press the buttons with force for the remote control to carry out our commands.

Take a dishwashing sponge, lather it with soap, and clean off the grease from the board, rubber base and halves of the remote control body. Then wash off the soap foam under running warm water. Wash away grease only with soap suds and nothing else.

Now all the elements need to be wiped dry and additionally dried with a hairdryer, or placed on a hot coil in the bathroom through a thin layer of cloth for about thirty minutes.
You gather your “little friend” and, sitting in a chair, switching channels, enjoy his work, and at the same time your own. As a rule, after such maintenance, the remote control begins to work like new.

If it doesn't help, go to plan B

Wipe the circuit board and rubber “mat” with alcohol using cotton swabs (not very hard - so as not to erase the contact coating). It is better not to use gasoline and acetone here.

Method for restoring contacts using foil

Method #1 Foil hole punch and double-sided tape. ( Without special glue and spraying).

To repair broken buttons we need:

Baking foil (it is more convenient to work with not too thin foil, since it is easier to separate it from the protective paper, which is glued on one side of the double-sided tape),

Double sided tape,

Hole punch or scissors.

A strip of 5-7 cm long double-sided tape needs to be glued to the foil, cut off the edges of the foil where there is no tape. Then we “pass” the foil and tape through the hole punch as many times as there are buttons we need to repair. We actually glue the finished circles onto the non-working areas of the remote control buttons. Checked - everything works!

Method #2 Foil superglue and scissors

Take a piece of thin foil (from candy wrappers, chocolate, for cooking), scissors and superglue. Cut small squares from foil to the size of the contact pads of the rubber “mat”. As an option: instead of foil, use foil paper, such as cigarette paper. By the way, I tried to use it, it lasted about six months. Let's see how long the foil lasts.

Superglue and foil squares

Using glue, carefully stick pieces of foil onto the contact pads of the “mat”. It should look something like this.

Let the glue dry and assemble the remote control. Everything should work.

Video instructions for repairing the remote control using this method

Old PC keyboard and metal tube

We take an old keyboard from a computer, take a metal tube, sharpen the edges until they are sharp and knock out holes with spots on the film and glue them on the contact pads of the “mat” remote control using suitable glue - not a single repeat in three years.

This method of repairing the remote control is what is called head-on.

A method for restoring button contacts for "chemists")

There are also more sophisticated methods, such as this method of repairing a remote control:

“One volume of silicone glue is placed in a glass bottle (you don’t need much, since the solution cannot be stored for a long time, and a few drops are enough for the remote control). Then approximately two volume parts of gasoline are added, the container is immediately closed and shaken vigorously. The silicone glue should be completely mixed with gasoline, forming a homogeneous milky mass. After this, one to two volume parts of graphite powder are added to the mixture, and it is again shaken vigorously. If the solution turns out to be too dense, it can be diluted again with gasoline.
The “old” contact pads of the rubber mat are cleaned with an ink (red) eraser or fine sandpaper, the remaining dirt and grease are removed with alcohol (gasoline cannot be used here!).
Now take a little of the prepared solution with a disposable syringe, select the optimal dosage on a piece of paper and then apply a drop of the solution to the conductive surface. Due to surface tension, a small but clearly visible swelling should appear. After the solution sets, it disappears. If something goes wrong, you can still intervene in the process using a cotton scarf.
The setting of the solution lasts about 24 hours. During this time, the rubber mat must remain motionless.”

Radical way. Wire and hammer

What do you need:

  • Copper wire
  • Hammer
  • Wire cutters
  • Tweezers

Repair:

take copper wire size 0.2-0.4 and flatten it using a hammer and a ratchet head (well, a wrench) at intervals of about 1 cm, it should look something like this,

schematic designation (“——” This is a wire, “O” is the place of flattening) (—-O—-O—-O—-) cut off the element (—-O)

we stick the left end of the element into the button next to the button, bend the flattened part of the element (—-O) over the conductive rubber

the same version from a different angle

everything is working!

Let's experiment. Contacts from the FDD or HDD cable

What do you need:

cable from FDD or HDD

Repair:

We take the unnecessary cable from the FDD or HDD, pull out the contacts from there, then it’s clear.
You can try to make something like a harpoon so that the contact does not fly out. Choose the size carefully so as not to prick your finger. see photo.

By the way, it works, in our opinion, much more clearly.

For those who are comfortable with a soldering iron

A small note: if the normal operation of the remote control stopped immediately after it was dropped on the floor, then first of all after disassembly you should pay attention to the ceramic resonator. Perhaps it has become unsoldered from the main board.

Here we see the reverse side of the PCB. On the left side is an IR LED, and the yellow square in the lower right corner is nothing more than ceramic resonator. Here are the contacts of the battery compartment and the only electrolytic capacitor for the entire remote control.

If all of the above methods did not help, you can try additionally going over its electronic components with a soldering iron to eliminate possible mis-soldering, especially for spring contacts for batteries.

With a well-tinned soldering iron tip, from the side of the printed conductors, touch the soldering point of the radio component lead, and as soon as the tin begins to melt, remove the soldering iron tip. Do not solder only the terminals of the microcircuit; you may overheat it or short-circuit the terminals and traces with solder. Typically, microcircuits rarely fail. But if it so happens that you need to solder the microcircuit, be extremely careful, and at the end be sure to check the pins and tracks so that there are no drops of solder left between them.

Now we can say with complete confidence that the remote control you repaired will work for a long time. In this way, almost all remote control units are reanimated.

Repair the remote control

The remote control doesn't work.
Each of us sometimes faces the question
How to repair a TV or DVD remote control ?
It's simple if you have even the slightest skill in repairing some kind of radio equipment.

I came across a lot of advice on the Internet like, but Is it worth repairing the old remote control?? Of course it's worth it. Have you ever seen the guts of your own remote control and

the rubbish that they will offer you in the nearest store? Then look:

The original remote control contains a normal microcircuit on a ceramic base and in a plastic case.
In the cousin there is a drop. The slightest blow or bend, and goodbye to the tracks. And they are sooooo thin there. And remote controls, as you know, love to fly.
Spring contacts in Chinese fakes are usually made anyhow. The rubber bands have a very thin conductive layer and wear out within a couple of months.

And don’t be fooled by the beautiful appearance of the new Chinese. It's not for long. You’ll wipe yourself off and won’t have time to look back.
As a last resort, if you are too lazy to bother with repairing your own remote control, use a Chinese one, but under no circumstances throw away the one that came with the TV. The time will come and you will pat yourself on the head. Like - wow, what a malades!

So, let's begin.

Disassembling a modern remote control
- a terrible sight for the owner of the device because after unscrewing all the screws, the remote control comes apart like a nut. If available, use hard, thin plastic, like a bank card. If not, use a blunt screwdriver. You need to open it carefully, but confidently. It won't get any worse for him.

1 . We take out the batteries and measure them with the device. Must be at least 1.5 volts. Or you can not show off and just replace them with new ones. You shouldn’t take super expensive ones, but cheap ones also have no place in your remote control. Because the assholes are flowing. And this is the death of the remote control. The electrolyte from batteries is not good friends with the copper of the tracks. Or rather, quite the opposite, but it won’t help you much

How to distinguish a good battery from a poor one?
You don't need to be an expert to do this. A good battery is usually almost twice as heavy as a fake one.
Appearance can also say a lot.

2 . Be sure to look at state of spring contacts. If they are clean and shiny, then move on. If they are dark or rusty or have a white coating, it’s time to sand them with sandpaper or a file.

3 . We wipe the surface of the board with graphite contacts with a cotton swab moistened with alcohol. I've been using wet alcohol wipes lately. I consider it a must to have them in my stock. It happens that there is nothing to wipe your hands with. And so at least clean off the remote control, even the kinescope with a thick, thick layer of soot
Ideally, it is better to wash the rubber band with warm water, a soft brush and dishwashing detergent (Together with the body. It will be more pleasant to hold in your hands). If everything is done in conditions close to combat, then an alcohol wipe will do.
The fat on the remote control is from our hands, by the way. Looking at the insides of the TV and the remote control, you can tell a lot about the owners of the devices. I've seen a lot in 20 years.

4 . It is best to check the remote control using a mobile phone camera. Unlike our eyes, the camera sees infrared radiation. If when you press a button you see a rhythmic blinking LED - happiness has smiled on you!

If it blinks without pressing a button, it means one of the buttons is stuck, or there is too much poop on the board.
By the way, the camera is unlikely to help you with this. There is an infrared filter there and you won't see anything.

5 . If there is no reaction to pressing the buttons, it must first be replaced quartz resonator. It can be of different types and you need to replace it with exactly the same one. There is no way to determine its integrity by looking at it, but believe me, this is the most fragile part in the remote control. Change it, and we'll see. The item is cheap.

6 . Least likely to die Light-emitting diode. Instead, use any infrared device that is similar in parameters and size. Or from another broken remote control.

7 . If your buttons work one at a time, you can:

A. Use a repair kit made from nickels and glue.

b. Take supermoment gel and foil from a cigarette pack, it is made specifically for these purposes. One side is conductive, the other is paper, on which glue is applied. Cut out patches slightly larger than the size of a button, use a toothpick to drip glue onto the elastic band, and use thin tweezers to form a patch and press it down.

V. Conductive varnish. It is profitable to buy only if you often repair the remote control, because a good one is expensive, and a bad one is not worth anything.

8 . There are still some cracks on the board, remote controls eaten by dogs and other rare phenomena. Here you need to judge its maintainability solely by its appearance.

Good luck to you!

The remote controls are not very different from one another. The repair technology is the same. Do the operations given in the article sequentially, from simple to complex, and you will succeed.

First, change the batteries and clean the contacts; if that doesn’t help, take it apart and look for external damage. And so on.

If the remote control does not work, but you need to make it (a rare remote control, expensive, or you just want to master it yourself), register on the forum:

and ask a question there. And we will definitely defeat him.

If the remote control is rare, then a photograph of the board from both sides, with sufficient clarity to see all the details, is highly desirable. It’s better to immediately write the backstory - it fell, water got in... And what they themselves did to make it work.
Added December 25, 2015. If your remote has stopped working after being dropped, replace the crystal first , and then check the rest of the circuit. It is he who most often suffers as a result of a fall. Maindon't start scientific research.

just replace the quartz with the same one

First, you need to decide and make sure that the remote control is really broken, and not the controlled device. How to do it? We read and do...
How to check the remote control.

You need a phone with a camera or a camera. The camera is already present in almost all phones, with the exception of the simplest ones.
We enter this mode on the phone and check the remote control,
point the emitting window at the camera
press any or more buttons.

If the remote control is working, you will see a small light in the window flashing on the phone screen,

If there are no flashes, then the remote control is broken.

There are faulty remote controls when there are flashes without pressing a button, this signals a short circuit of some button or its contacts. How to fix a remote control with such a defect, read on... Do not forget about the batteries, they should be replaced with new ones, we check the contacts and remove oxides. You should choose good batteries for remote controls. Contacts from cheap batteries often corrode. How to repair a remote control with such a fault? Be sure to completely clean the contacts from plaque to a metallic shine and moisten the contacts with a liquid with a high alcohol content. If you doubt the suitability of the batteries, you can temporarily use a working remote control for testing. If this does not help and the remote control does not work, proceed to repairing the remote control yourself. To do this you need to disassemble it.

Remove the cover and batteries. Inspect the remote control housing for mounting recesses. Often there are screws under the battery cover.
It is very common to fasten parts of the remote control body with clips and glue, so it is impossible to disassemble them without damage. When opening such a remote control, you should be careful not to injure your hands or break the instrument. Using a nail file or a spoon that fits well into the groove between the top and bottom of the remote control, gradually snap off the clips or break the glued groove, prying up the lower part of the remote control and effortlessly moving it around the body. The half remote control consists of
Boards with an integrated microcircuit, quartz, infrared diode, contacts on the board, buttons, conductive tracks, contact group for power elements.
Rubber button mat with conductive contacts

Frequent malfunctions
The buttons on the remote control are stuck.
you need to press hard on the remote control buttons
Only works at very close range
If you hit the remote control it works, it doesn't work

The main reason why the buttons on the remote control do not work is that the button contacts are dirty. Dirt can interfere with closing the contacts of the buttons or, on the contrary, shorts them. And the operating algorithm of the remote control is such that when several buttons are pressed simultaneously, the command from the remote control is blocked and, of course, the remote control does not work. Therefore, it is necessary to clean the contact pads on the board and clean the contact spots on the rubber mat. There are two types of contact patches on buttons.
With graphite coating and conductive rubber. The graphite coating gradually wears off and leaves marks on the contact pads of the board, contaminating and shorting them. If you're lucky, you have a remote control with conductive rubber, but even here, over time, problems with dirt and oxides appear. The contact pads on the board can also be made in different ways, either with graphite coating or copper conductors.
Often, when you open the remote control, there is oily dirt on the board, this is condensation of oil from the skin of your hands. If you have been using the remote control for a long time, this dirt will already be dry on the buttons and on the top of the case too. When you have to press the buttons with force for the remote control to work or they are pressed poorly, this is 100 percent contamination! If you take the remote control apart, you will understand what I'm talking about. My photo shows a clean one, later I will definitely replace the photo where everything will be clearly visible. How to repair a remote control with your own hands with such a problem? If the buttons are not coated with graphite, a good cleaning will help.

We clean the board with a cotton swab soaked in alcohol or vodka, do not use colognes, they leave a film and it will be even worse. We wash the rubber keyboard and case in water using a grease detergent and a hard brush from an old toothbrush. Dry it well. Using an eraser, we go over the rubber heels on the rubber mat and the contacts on the board. We assemble and check the remote control. It works, great! The site “How to Do It Yourself” helped you.

How to make for remote controls with graphite coating on the buttons, restoring contacts is described below.
How to repair the remote control with your own hands in case of other malfunctions

If the remote control does not work even after this, then in order to fix the remote control, you will then need some knowledge of electronics and the ability to solder.

We check the soldering of the contact springs for the batteries on the board and the soldering points of the emitting diode. We carefully inspect and solder defective soldering joints.
The remote control stopped working after being dropped.

I want to warn you that sharp blows are dangerous for them; the ceramic quartz on the board is very fragile. To make the remote control, it needs to be replaced.
The remote control only switches at close range

The batteries may need to be replaced or the emitting diode may be worn out. First, we check the batteries by replacing them, and if there is no result, we change the emitting diode.
The buttons on the remote control don't work.

Sometimes cleaning does not help, the rubber loses its electrically conductive properties over time, or the graphite coating on the spots of the rubber mat wears off. How to fix a remote control with such buttons? Using a remote control repair kit, which includes a small tube of silicone glue and conductive rubber contacts in the form of patches.

The old patch is carefully cut off with a blade and a new one from the kit is glued in its place. The kit is enough to repair 3-5 remote controls.

Another option for making the remote control work is to use electrically conductive glue “kontaktol”, which we apply to the grease-free spots of the rubber mat. But these methods of restoring remote controls are expensive and make sense when you need to repair a lot of remote controls or the remote control cannot be found on sale. Microcircuits in remote controls rarely fail. I also advise you to pay attention to mechanical faults.
broken paths,
bad soldering,
closing at the intersections between the printed track and graphite conductors, if any are present, they are applied on top of the former. The latter is very insidious, and can manifest itself at times. You should pay attention if the batteries in the remote control are quickly discharged.
Let me add that such malfunctions are typical not only for remote controls, all devices with similar buttons suffer from this, but they can also be repaired with your own hands

Today, almost all electronic devices used in everyday life are equipped with remote controls. TVs are no exception. How else can you change channels without leaving the couch?

The remote control, being an intensively used device, often fails. It either stops functioning altogether, or copes with its responsibilities partially.

What do the most impatient and comfortable some of us do when? That's right, they are trying to buy a new one as quickly as possible. But if you have the desire and a few tens of minutes of free time, you can try to repair it yourself.

In this article we will talk about why the remote control fails, and also consider ways to resuscitate it at home.

The TV remote control does not work: causes and symptoms of malfunction

The remote control device may lose its functionality either due to some technical problems or due to careless handling. So if yours is broken remote control for tv, before you start disassembling it for subsequent repairs, you should determine for yourself what signs of malfunction it shows. This will make it easier to plan further actions.

Most often, a remote control malfunction is characterized by:

  • visible and suspected mechanical damage;
  • lack of response when pressing some buttons (other buttons work);
  • complete lack of response (all buttons do not work).

Let's consider these signs in the context of possible malfunctions.

Mechanical damage

If there are obvious traces of mechanical damage on its body, this may indicate that it was simply dropped on the floor or was deliberately attempted to be rendered inoperative. The consequences of such treatment of the device may be:

  • lack of contact between the batteries and the electrical terminals of the remote control;
  • damage to the transmitting LED;
  • violation of the integrity of conductive paths and/or leads of electrical components on the board.

The TV remote control does not work: what to do and where to start

The best place to start diagnostics is with the batteries. When a device falls, they are often the cause of its failure. The test itself consists of removing the remote control cover and checking the position of the batteries. If necessary, they must be reinstalled, observing the polarity. Pay attention to how tightly their contacts are in contact with the electrical terminals of the device. If the batteries are loose, you may need to bend the negative terminals (springs).


If after such events remote control for tv earned, close the lid and continue to use it further. If this does not happen, we move on to the next stage of diagnosis.

Battery charge

After removing the cover of the device to check the batteries, do not be too lazy to check their charge level. Although the remote control consumes a minimum of electricity to ensure its operation, the batteries gradually run out.

The test is best done using a conventional voltmeter or multimeter. To do this, you just need to measure the voltage at the contacts of the batteries. It should not be less than 1 V.

If you do not have such devices, check batteries for TV remote control possible by using them in another remote control device, for example for a DVD, stereo system, air conditioner, etc.

You can also insert known good batteries into our device. After making sure that they are suitable both in size and in terms of the output voltage, remove them from the other remote control and install them in the one being diagnosed. Did the check show that it was the batteries that failed? Just replace them.

Checking the LED

The transmitting LED plays a major role in the operation of the remote control. It consists of transmitting an infrared signal of a certain frequency to a special TV receiver. First, inspect the LED for damage. If it is broken, the only solution is to replace it. You will have to go to a radio market or a store that specializes in selling radio components, buy the same element and solder it in place of the damaged one.


Does the LED look intact? Check how it works. This is impossible to do with the naked eye, since the human eye does not perceive infrared radiation. One of the modern devices equipped with a camera will help here. It could be a mobile phone, smartphone, tablet, etc. Turn on the camera on it and point it at the remote control LED. Now try switching channels while looking at the device screen. With a working diode, you will definitely see light signals when you press the remote control keys. But if there is no reaction, most likely the problem is not with the light element.

Damage inside the device

Mechanical damage may be hidden from your eyes. If The TV remote fell and doesn't work, and something is dangling inside, there is a possibility that he received a closed “injury”, which put him out of action. As a result of a fall, a wire may break off, a lead, for example, of a capacitor may fall off, or a conductive path may crack. Here you will have to completely disassemble the device.

If the board or its elements are damaged, it is better, of course, to entrust them to professionals, but if you have ever held a soldering iron in your hands, you can try to deal with it yourself.

First, let's open the device. You're lucky if your TV remote control housing is held together with screws. In this case, you need to unscrew them and disconnect the parts of the device. If the case is fastened with internal latches, you will have to work a little.

A knife with a thin, dull blade will help you disconnect the parts of the remote control. It must be inserted between the halves and, gently squeezing, disconnect them from each other, passing in a circle. When this is done, disassemble the remote control and carefully inspect the circuit board for damage. For these purposes, use a magnifying glass. Small defects may not be visible to the naked eye. It is also advisable to ensure good lighting of the area where the inspection will be carried out.


Start checking from the terminals that go to the batteries. Next, inspect all the tracks, and then the electrical parts. If you find a break in the electrical circuit of the remote control, restore it by repairing or replacing the damaged part. If damage to the microcircuits is detected, it is better to buy a new remote control than to try to repair it. At least it will be cheaper this way.

When individual buttons do not work

Often the reason is that TV remote control doesn't work, is the condition of the rubber keyboard. The lower part of the buttons is covered with a conductive graphite layer, which, in fact, closes the contacts located on the board. It happens that this layer wears out from constant use, and it also happens that dust, moisture, and foreign objects get between it and the contacts.

Wear usually occurs on the keys we use the most:

  • on-off;
  • switching channels;
  • increasing or decreasing the volume level.


Unidentified oily liquid

Having discovered that The TV remote control doesn't work, and upon disassembling it, you can see a colorless oily liquid on the bottom of the keyboard. Do not rush to blame your relatives if one of them spilled sunflower oil or sweet tea on the device. This liquid is nothing more than oil secreted from the pores of the fingers. During operation of the remote control, it settles on the buttons, as a result of which contact between them and the pads is lost.

This problem can be solved very simply. It is enough to disassemble the remote control, wipe the board and the bottom of the keyboard with alcohol, and the device will work like new. Before starting use after this procedure, do not forget to dry the wiped elements.

Is it possible to restore a worn-out graphite layer?

What should I do if the conductive graphite layer on the bottom of the remote control keypad has worn off? It can be restored. with damaged conductive coating involves removing it and creating a new one in its place. But what is it made of?

There are two options here. The first is to buy a special kit for repairing remote controls at a radio parts store. This set includes a tube of silicone glue and several dozen rubber patches (coverings on the lower parts of the buttons) coated with the same graphite. You are required to disassemble the remote control, carefully cut off the old pads, and stick new ones in their place. Such repairs allow you to completely restore the device for a long time.

The second option does not involve any costs at all. Take regular chocolate foil, cut out the required number of pads from it, observing the size, and stick them on top of the worn-out patches. Of course, this budget repair will not ensure trouble-free operation of the remote control for many years, but believe me, it will still serve.

Will film help?

You've probably seen remote control devices wrapped in plastic film. This method was undoubtedly invented by our compatriots in order to protect the remote control from the possible consequences of careless handling. Yes, the film can temporarily protect the device from moisture and dust. But over time, it loses its protective properties due to the same intensive use. Whether it is worth turning the remote control into an incomprehensible and funny object is up to you to decide.

How to extend the life of your TV remote control

To keep your TV remote control working as long as possible, use the following tips:

  1. Try to handle it carefully, avoiding dropping it on the floor.
  2. Do not give the remote control to children and protect it from “encroachment” by pets.
  3. Monitor the status of the LED.
  4. Don't forget to change batteries on time.
  5. Do not use the remote control when your hands are dirty or while eating.

How to disassemble the remote control?

Every home has household appliances that operate via remote control. Over time, the remote control may fail for various reasons. And in order to repair or clean the device, you will need to disassemble it.

How to disassemble the remote control

To perform this procedure, you only need a small screwdriver or a kitchen knife (preferably a dull one).

  1. Before starting work, you must remove the batteries or accumulators by opening the back cover of the device.
  2. If there are fixing fasteners in the battery compartment, then the remote control can be disassembled by unscrewing them. Simply unscrew the bolts or screws to disassemble the device body. Otherwise, the upper and lower parts of the housing are connected to each other by internal snap elements.
  3. Insert the blade of the screwdriver into the junction of the body parts and carefully pry up one of them, applying sufficient force.
  • The disadvantage of this method is that there is a risk of scratching the remote control body or even breaking the snap fasteners. Therefore, if you do not want to spoil the aesthetic appearance of the device, then use a plastic or rubber tool;
  • Before disassembling the device, lay down a white sheet of paper so as not to lose small parts;
  • If you have fasteners, remember their location, as difficulties may arise during further assembly;
  • If the batteries are in an oxidized state, they need to be replaced. If possible, use rechargeable batteries (they do not oxidize and have a long service life). For proper operation of the remote control, you will also need to clean the contacts and remove dirt;
  • If the battery compartment cover is broken, it is better to replace it;
  • Be careful with small parts and microcircuits.

How to clean your remote control

  1. Remove the batteries or accumulators from the compartment and disassemble the device as described above.
  2. The disassembled device consists of a housing, a microcircuit and a rubber gasket with buttons for control. All elements must be thoroughly cleaned.
  3. Carefully remove dirt from the chip using a soft cloth with a cleaning solution (you can use a small amount of shampoo, dishwashing detergent, or regular soap). Do not use hard brushes or sponges under any circumstances, as you can damage the coating of the microcircuit, on which the functionality of the remote control depends. As a last resort, you can clean the circuit by hand. For a better effect, the cleanser can be replaced with alcohol (cologne, vodka and other alcohol-containing liquids are not suitable). When working, do not wet the board too much. At the end of the procedure, dry the circuit thoroughly (you can use a hairdryer).
  4. The rubber gasket and body can be cleaned of dirt and grease by rinsing with a product under running warm water. Allow the components to dry thoroughly to avoid rapid oxidation of the internal contacts of the remote control or improper operation of the device (use a hairdryer or dry the parts on the battery).
  5. Then assemble the remote control, insert the batteries and check the functionality of the device.
  6. If some of the buttons do not work, then the problem is not due to dirt. In this case, you will need to replace the faulty keys. To fix the problem, you need to purchase a repair kit (you can buy it in the household goods department). The kit includes new buttons and silicone glue. Glue the buttons instead of the old ones onto the rubber gasket and let them dry.

By the way, the correct operation of the remote control depends on its settings. Find tips on automatic and manual setup in our article.

The most common defect unintentionally incorporated into the design by remote control manufacturers is poor contact of the positive and negative terminals with the power supply. Made from an alloy that is not entirely suitable for such devices, they bend easily and lose their former elasticity during operation (especially after the warranty period has expired). Damage to the springiness of these terminals can be eliminated quickly and permanently by placing non-hard rubber (for example, an eraser) between them and the end of the board, which will reliably press the contacts to the batteries.

The second most common defect in the remote control is the deterioration of contact between the graphite printed elements of the board and the conductive rubber pressed against them by the control buttons. The reason is fat trapped between the buttons and contacts of the board, a decrease in the quality of the rubber itself, from which after 2 - 3 years of operation an oil-like substance is released as a result of a chemical reaction. By covering the printed circuit board, it interferes with the contacts.

Another common malfunction is when the most commonly used buttons stop working, or work, but only when pressed hard. This wears out the conductive coating of the rubber base contacts. The rubber contacts under the buttons physically wear out, losing conductivity. The graphite elements of the printed circuit board are also subject to wear. In such cases, you need to replace the rubber with buttons with new ones (they are sold on radio markets). This repair kit consists of small conductive circles and glue, which you will need to glue on top of old, worn conductive rubber-based contacts.

And the printed circuit board must be carefully cleaned of the viscous liquid released with a dry soft cloth. Graphite contacts can be easily restored using a soft pencil.

But - attention! Contrary to the common practice among radio amateurs, under no circumstances should you wipe the graphite contacts on a printed circuit board with alcohol, cologne (and especially solvents). Graphite is destroyed by alcohol-containing substances and solvents.

You can make sure that the remote control board is working as follows. Having assembled the remote control in the case, do not rush to place the rubber mat with buttons in its designated place. But the power source should be inserted. Then, using a mini-pointer twisted from foil, you need to alternately (through the holes for the buttons) touch all the graphite contacts on the printed circuit board.

If the TV responds normally to commands from the remote control, then the board of the remote control is working, and only the rubber with the buttons needs to be changed.

If there is no reaction, then the cause of the remote control failure may be the disconnection of infrared emitters, capacitors, quartz resonators, or microcracks on the board itself as a result of falls and impacts.

It happens that you can’t buy new tires. However, you shouldn’t despair - you need to restore the old one. It is necessary to separate the black contact plates from all the buttons on the back of the rubber mat. Then use any rubber glue to glue new ones onto the vacated spaces. You can find functional contact plates in many old electronic devices that are considered unsuitable for other reasons: calculators, push-button telephones, etc.

Contact plates made of conductive rubber are carefully removed, cut with a sharp blade or scalpel to the required diameter and then glued onto the rubber mat of the remote control. Considering that the “donor” plates can have different dimensions, the excess is cut off from them with a blade, ensuring that the thickness of the plates does not exceed 1 mm (otherwise the remote control buttons will be constantly “pressed”).

Other repair methods

First, you need to disassemble the remote control. Despite their different sizes and appearance, all remote controls are essentially the same.

We take out the batteries and at the same time look in the battery compartment for the mounting screws, which may be located under the factory stickers. Use a screwdriver to press down on the sticker; if it pushes through, it means there is a screw underneath it.

The remote control body consists of two halves, connected to each other either with screws, or with a latch, or using both methods. Try using a thin knife to carefully separate the halves of the remote control.

We carefully insert the tip of the knife into the gap between the halves of the body and try to push them apart until a click appears. A click indicates that one of the latches has opened. Here it is important to find and unlatch the first latch, the rest will go easily. Try to do everything carefully so as not to break the latches, and even if you break one or two, it doesn’t matter, it won’t make the remote control close any worse: checked. You can also separate it with two thin screwdrivers, or combine a knife and a screwdriver, as you wish.


If you are disassembling the remote control for the first time, it is preferable to use a knife and a screwdriver. First, insert the tip of the screwdriver into the gap between the halves of the case and, slowly moving the screwdriver along the case, look for the first latch. As soon as you find it, you snap it off, but leave the screwdriver stuck near the latch, and then continue to work with the tip of the knife. When you reach the next latch with your knife, you can insert a second screwdriver and continue moving with the tip of the knife, or continue moving with the first screwdriver. In a word, do what is most convenient for you.


When, for example, the left half has opened slightly, carefully, without removing the knife, move it along the body, unlatching the latches, until the remote control is completely opened. Carefully remove the board and rubber base with buttons. Pay attention to the battery compartment. There are grooves into which the spring contacts are inserted, so before you pull out the board, remember how they fit in the grooves so that there are no questions during assembly.

If you carefully look at the board from the side of the tracks and at the rubber base from the side of the contacts, you can see that in some places they seem to be smeared with a thick layer of adhesive mass. This is fat. Because of this fatty layer, there is poor contact between the graphic coating of the board and the contacts of the rubber base, which is why we have to press the buttons with force for the remote control to carry out our commands.


Take a dishwashing sponge, lather it with soap, and clean off the grease from the board, rubber base and halves of the remote control body. Then wash off the soap foam under running warm water. Wash away grease only with soap suds and nothing else.

Now all the elements need to be wiped dry and additionally dried with a hairdryer, or placed on a hot coil in the bathroom through a thin layer of cloth for about thirty minutes.
You gather your “little friend” and, sitting in a chair, switching channels, enjoy his work, and at the same time your own. As a rule, after such maintenance, the remote control begins to work like new.

If it doesn't help, go to plan B


Wipe the printed circuit board and rubber “mat” with alcohol using cotton swabs (not too hard, so as not to erase the contact coating). It is better not to use gasoline and acetone here.

Take a piece of thin foil (from candy wrappers, chocolate, for cooking), scissors and superglue. Cut small squares from foil to the size of the contact pads of the rubber “mat”. As an option: instead of foil, use foil paper, such as cigarette paper. By the way, I tried to use it, it lasted about six months. Let's see how long the foil lasts.


Superglue and foil squares

Using glue, carefully stick pieces of foil onto the contact pads of the “mat”. It should look something like this.


Let the glue dry and assemble the remote control. Everything should work.

Video instructions for repairing the remote control using this method

This method of repairing the remote control is what is called head-on.

There are also more sophisticated methods, such as the method of repairing a remote control:

“One volume of silicone glue is placed in a glass bottle (you don’t need much, since the solution cannot be stored for a long time, and a few drops are enough for the remote control). Then approximately two volume parts of gasoline are added, the container is immediately closed and shaken vigorously. The silicone glue should be completely mixed with gasoline, forming a homogeneous milky mass. After this, one to two volume parts of graphite powder are added to the mixture, and it is again shaken vigorously. If the solution turns out to be too dense, it can be diluted again with gasoline.
The “old” contact pads of the rubber mat are cleaned with an ink (red) eraser or fine sandpaper, the remaining dirt and grease are removed with alcohol (gasoline cannot be used here!).
Now take a little of the prepared solution with a disposable syringe, select the optimal dosage on a piece of paper and then apply a drop of the solution to the conductive surface. Due to surface tension, a small but clearly visible swelling should appear. After the solution sets, it disappears. If something goes wrong, you can still intervene in the process using a cotton scarf.
The setting of the solution lasts about 24 hours. During this time, the rubber mat must remain motionless.”

We take an old computer keyboard, take a metal tube, sharpen the edges until they are sharp and knock out holes with spots on the film - not a single repeat in three years. We glue them onto the contact pads of the remote control “mat” using suitable glue.

A couple more methods from folk craftsmen

What do you need:

Method 1

Copper wire
Hammer
Wire cutters
Tweezers

we take copper wire size 0.2-0.4 and flatten it using a hammer and a ratchet head (well, a wrench) at intervals of about 1 cm, you should get something like this, a schematic designation (----- This is wire, “O” is place flattening) (--O--O--O--O --O--O--O--O--O--O--O),
cut off the element (-–O), stick the left end of the element into the button next to the button, bend the flattened part of the element (-–O) over the conductive rubber



The second option is more tempting, you can try to make it like a harpoon so that the contact does not fly out. Choose your size carefully to avoid pricking your finger. see photo.

By the way, it works, in my opinion, much more clearly.


For those who are comfortable with a soldering iron

If all of the above methods did not help, you can try additionally going over its electronic components with a soldering iron to eliminate possible mis-soldering, especially for spring contacts for batteries.


With a well-tinned soldering iron tip, from the side of the printed conductors, touch the soldering point of the radio component lead, and as soon as the tin begins to melt, remove the soldering iron tip. Do not solder only the terminals of the microcircuit; you may overheat it or short-circuit the terminals and traces with solder. Typically, microcircuits rarely fail. But if it so happens that you need to solder the microcircuit, be extremely careful, and at the end be sure to check the pins and tracks so that there are no drops of solder left between them.

Now we can say with complete confidence that the remote control you repaired will work for a long time. In this way, almost all remote control units are reanimated.

A television is a technical device, a complex mechanical system that operates on physical-optical, wave and other principles and, like all equipment, it is prone to breakdowns. The same applies to the well-known control panel, the primary model of which was created by Nikola Tesla himself at the end of the 19th and beginning of the 20th century. Today, breakdowns of the control panel are not uncommon, but what to do in such a situation, and is it possible to cope with the problem yourself? More on that later.

What is a TV remote control

Over time, remote controls became more and more advanced and self-sufficient, which led to the creation in the second half of the 20th century of a remote control (RC), capable of making an industrial machine work at a distance.

This device is still being improved to this day and makes it possible not only from a close distance, but also from other rooms, to control household technical appliances, in particular the TV, without much difficulty.

What can we say if we managed to create a car or even a helicopter using a remote control. Among the manufacturers of high-quality equipment that have gained a foothold in the market and have earned a name for themselves, several can be distinguished - Samsung (about which read in more detail below), Philips (Philips), Sony (Sony), Panasonic (Panasonic), LG (LG), as well as a set of common models , for example, Supra, Mystery, models based on the board adam24p20g, rmctph1ap1, rmctpj1ap2, z1025, rmctpf2ap1.

The classification of TV remote controls depends on a variety of criteria, for example:

  1. Remote controls with one built-in program, operating only on its basis.
  2. Universal control panels are those that include several programs at once.
  3. The so-called learning remotes, which means that with the proper desire and minimal dexterity, you can program such devices to your taste and literally make them your own by adding new programs.

The TV remote control most often operates on the basis of infrared electromagnetic radiation, which is not visible to the human eye, but allows you to give commands literally from almost any distance. The principle of operation in general terms is an interconnected system of programmed commands, activated by pressing a certain button, which sends a signal to further details and so on along magnetic waves to the TV itself.

Analysis of the Samsung TV remote control

As already noted, one of the most common and well-known manufacturers of television devices and remote controls for them is Samsung, which today has a strong reputation and firmly holds its position in the market.

The relatively recent development from Samsung Smart TV deserves special attention.

In a short time, Smart TV has earned public recognition and a high rate of positive reviews. The most convenient and sensitive touchpad (sensor) is built in, allowing you to quickly and habitually work in an accessible browser or execute other commands, as well as a lot of other obvious advantages.

The smart system, like the control panel for the TV with it, is a convenient service that has the following features and advantages:

  1. Allows you to control several devices at once, starting with the TV itself, which has the Smart program, including the set-top box connected to it, and ending with other native programs and players.
  2. Convenience and modernity, because this program is connected to the network and allows you to most comfortably adapt the TV and DVD to your tastes and quickly adapt to new preferences.
  3. Manufacturability, which is determined, for example, by the ability to control by searching using voice commands, and the presence of a modern and high-tech tuner.

It doesn’t matter if you have lost the remote control, because the program allows you to install an application on your phone - this will serve as a replacement for it, as well as preview some functions in the radiotelephone. Easy to connect, because, like almost everywhere else, you only need an audio cable.

Reasons: why the TV does not respond to the remote control

Most of us have faced the problem where we desperately try to switch to our favorite TV channel, pressing every possible button and making every possible attempt, but alas, the remote shows no signs of life, some heat up after turning on, and the TV will not respond to its imperatives. and the channels do not switch or only with difficulty, and the buttons themselves either are not pressed at all or to no avail, no matter what they do. It’s good if the TV still turns on.

The nature of such problems may lie in the following possible aspects:

  1. The energy of the batteries was simply spent, due to which the remote control began to lose contact with the TV, because it is with its help that the basic impetus to the functioning of the device occurs.
  2. The buttons themselves stick, become stuck (seized), and the buttons themselves do not work well, which can be found on a remote control that was previously filled with liquids, received mechanical damage, or was used incorrectly, which is also a fairly common problem with all remote controls.
  3. Natural wear and tear, which implies abrasion or mechanical damage to the surface receiving the signal, due to which the entire remote control (push-button coating or touch plates under the buttons) stopped working.

Temporary wear and tear is also quite likely, since I don’t always wash my hands before using the remote control, and many people like to snack on something that leaves large particles of seasoning, crumbs and the like, which will certainly clog the internal cavity of the remote control over time.

This breakdown will prevent all or only some of the most important parts from working.

Don’t rush to throw away the device with the black inscription “Broken” and shake your wallet in anticipation of a new one, because often remote control malfunctions can be solved by yourself and in the shortest possible time at home, by carrying out disassembly and short repairs.

Instructions: how to clean the TV remote control

Let's start with the most superficial and simple task - cleaning the control panel with your own hands, and thereby restoring its performance and functionality. It should also be noted that the remote control should be cleaned periodically.

In order to realize your plans, you should first understand the main components of each remote control, the diagram of which looks like this:

  1. The case is the base on the surface of which there is a touchpad or buttons, and in itself the entire operating mechanism.
  2. Covers in certain areas of the body, designed to hide and additionally secure batteries and all other elements of the remote control.
  3. A printed circuit board or microcircuit to which a rubber contact plate is attached and adjacent, designed to convert the signal of a certain pressed button into a sequence of electromagnetic pulses and then transmit them to the TV.
  4. An emitter (a system of two transistors, resonators, capacitors and resistors), which actually performs the function of generating electromagnetic waves.
  5. A plate of plastic or rubber buttons.

As for the process itself, cleaning the inside of the tricolor remote control looks easy. It is necessary to prepare a repair kit with the necessary basic tools with which we will revive the device. We unscrew the bolts or screws, open the latches and expose the insides of the patient; it is best to open the case with a plastic or thin metal card so as not to tear or break the clamps and latches.

Carefully take out the board, and if there are clamps on it, first open them too. Next, you should get, as a rule, rubber buttons. Wash the parts, but everything should be done extremely carefully.

It is better to simply wipe the electromagnetic parts thoroughly with a damp cloth or rag to remove dust.

The board (chip) should be carefully wiped with a small amount of alcohol, but lubricating the rubber plate is unacceptable, because there is a risk of washing off and erasing all the necessary contacts.

A distinctive feature of LG remotes is that the buttons are mostly built into the top panel of the case and are not removed along with the internal components, which makes them somewhat more difficult to clean, but this can be solved by putting a thermal cover or other film on it.

Schematic analysis of the LG remote control looks like this:

  • First you need to remove the batteries located behind the cover on the back of the remote control;
  • Gently run a thin surface along the crack, unhook the clips, and open the lid;
  • Remove the board and remove the rubber contact plate;
  • After carrying out the necessary procedures, reassemble the remote control in reverse order.

Fundamentally, disassembling the LG TV remote control is no different from disassembling any other remote control, with the exception of a number of special properties inherent to a particular manufacturer. After all this has been done, you should dry the elements using air conditioning and reassemble in the reverse order, then check the operation and the remote control for functionality and correct assembly.

This can be done using any camera that the remote control sensor is pointed at and any button is pressed.

After the final check, feel free to use the remote control. Using this procedure, you can significantly improve performance and even return the remote control to its original quality, even for those who are not particularly versed in technology.

The nuances of repairing TV remote controls

As noted above, you can carry out initial preventive repairs and restoration, or more in-depth repair of the TV remote control yourself without preparation.

However, the following should be considered:

  1. If you really want to, you can repair the remote control yourself.
  2. They will charge a decent amount for the work for banal operations, unless we are talking about replacing the main components, which, by the way, you can also replace yourself.
  3. Most likely, this will take time, at a time when personal repairs will cost a maximum of an hour of free time.

However, if we are talking about serious damage, for example, to the board or contacts on the rubber plate, in order to replace it, the services of a qualified specialist may be useful to repair and restore it.

DIY TV remote repair steps

We are considering a case of serious internal failure, when the total mass of buttons works, and random buttons that break most often, such as Guide on Philips models, Set, Select, Source, Pairing and other standard ones.

In this case, you should do the following:

  • It is necessary to disassemble the remote control according to the diagram described above;
  • Next, you should clean everything according to the scheme described above;
  • Thoroughly clean the platform and plate from grease and dust;
  • Apply glue to the non-functional button;
  • Pour in a small amount of pre-prepared graphite (can be torn off from a graphite plate or pencil);
  • After the glue has dried, get rid of the excess;
  • Assemble the remote control and check the operation of the button using the previously described method.

DIY TV remote control repair (video)

In conclusion, it is worth noting that repair services can be provided by well-known and affordable companies that repair equipment, be it Rostelecom, Beeline, Zala (hall) or another organization. Take care of your appliances and they will last a long time.

The remote control body is held on by latches located on the top or bottom of it.

Insert a screwdriver into the junction of the housing parts. Pry the upper or lower part of it and, applying force, disassemble the remote control. You will see that it consists of three main parts: the Body;
Remote control chip;
Rubberized pad with control buttons

Wipe the chip with a cleaning solution. Remove dirt from the remote control housing TV and on a gasket with buttons. If the contamination is too strong, such as happens from many years of using the remote control in a plastic bag, thoroughly rinse all its parts with water, except, of course, the microcircuit. The main thing is to let them dry thoroughly before assembling the remote control, so as not to provoke accelerated oxidation processes in the already assembled device.

Every home has household appliances, which are usually supplied remote control remote control. This remote control is very convenient, as it can be used to control equipment from a distance. However, remote controls very often break down and require repair. How to disassemble the remote control to repair it?

You will need

  • A screwdriver made of plastic or hard rubber, a blank sheet of paper.

Instructions

Prepare a clean surface. It is best to lay down a white sheet of paper, as small details that are very easy to lose will be clearly visible on it. Study your remote control carefully. The assembly principle for all remote controls is approximately the same, the difference is in the location of the mounting bolts and latches. Read the instruction manual for the household appliance whose remote control you need to disassemble. Very often there is a diagram of the structure of the remote control. It will help you disassemble the remote control correctly without damaging any parts.

Remove the cover of the compartment where the batteries are located. Inspect the latch of this compartment. It very often breaks and begins to detach itself from the body. If the latch is broken, it must be replaced, since gluing the broken piece is useless. Remove the batteries. Make sure that the batteries are not oxidized. Inspect the contacts in the compartment. They must be clean, free of stains and foreign coating. If the batteries are oxidized, you will have to clean all the contacts, otherwise the remote control may not work. It is also recommended to buy rechargeable batteries instead of batteries. They are good because they do not oxidize. You can also save money by using batteries.

Now make sure that all the bolts on the body are removed, if any. Try to remember the location of the removed bolts, as they may vary slightly. Now take a plastic screwdriver, insert it into the gap between the two parts of the remote control and press lightly. Now your task is to find all the internal latches and open them. Use a screwdriver only made of plastic or hard rubber, as a regular screwdriver can easily damage the plastic of the remote control. Press very carefully so as not to inadvertently break the latches. Once you have opened all the latches, you can remove the parts of the remote control. Be extremely careful, as there are a large number of small parts inside that can be easily damaged. If necessary, clean the rubber keyboard.

Carry out all work with extreme caution so as not to accidentally damage parts or latches.

The work of an electrical appliance repairman, for the most part, is to repair not some complex equipment, but “light combat” equipment - remote controls remote control from TVs or radios. These devices become unusable much more often than the devices themselves that are controlled by these remote controls. Most of the faults that occur in these remote controls could be done by any man if he took the remote control apart. In this article you will learn what you need to do to fix your remote control. TV at home.

You will need

  • Remote control, soldering iron, set of replacement rubber products.

Instructions

Inside the remote control body, under the channel keys, there are small rubber products that are shaped like a circle with a hole. If you replace these rubber bands, the remote control will take on a new life. The problem may also lie in dirty contacts to which the keyboard buttons are adjacent or in a break in some wires. To solve the problem of “dirty contacts”, it is enough to use cotton wool soaked in alcohol or cologne. To solve the problem of “broken wires”, you should use a heated soldering iron. Just solder any connecting wires that are out of place.

Unplug the TV. With this action you will de-energize it. Never try to disassemble the TV while the plug is plugged into the outlet. This may cause a short circuit. Usually the cord is disconnected from the TV body, so it is better to remove it so that it does not get in the way in the future. Cover the surface on which you will disassemble the TV with a light, not very thin cloth. On light colors, small details will be very clearly visible.
