DIY TV remote control repair

The TV does not turn on with remote control Or don't you switch channels, don't adjust the volume, and the other buttons work fine? Such symptoms malfunctions of the remote control familiar to almost everyone. This malfunction of the remote control is the most common and has been going on since the appearance of the remotes themselves, but the manufacturers have not taken any radical measures to eliminate them. With almost 100% certainty, the cause of such a malfunction is the erasure or contamination of the conductive layer of the contact buttons. There are two resumptions of the remote control in this case:

- First - do not bother and buy a new remote control. It is worth noting that by purchasing a cheap (not original) remote control, you run the risk of encountering the same or another breakdown in the first month. Therefore, if you decide to change the remote control, then, if possible, buy the original remote control and not in the “sharashkin cantor”. This will save you nerves and money.

- Second - repair the remote control yourself. It does not require knowledge of electronics and is available to anyone, regardless of gender and age. Apart from the battery, which you also remove from the remote control, there is no “dangerous” electricity "in the remote control. Even if something does not work out, then the first method always remains in stock, and the money for this will require rather modest ones. But why pay if you can do everything yourself in 15-20 minutes, besides, any new remote control will have the same fate and the experience of the first repair will not be in vain.

It is worth noting that with rare exceptions, repair shops do not carry out such a restoration, or the cost will be comparable to the price of a new remote control. If you decide - then do it yourself, everything is simple, but this article will help you.

At the beginning, let's dwell on

Diagnostics of malfunction of the TV remote control, tuner, air conditioner or any other equipment

- If the device does not turn on with the remote control and no buttons work, then replace the batteries first. With weak batteries, it is possible to respond to the buttons once or twice in a row, then it does not respond, after some time (20-30 minutes) it reacts again once or twice. This also indicates worn out batteries that need to be replaced. If this does not help, then there is a malfunction in the electronics. Further, depending on your qualifications and desires, you decide on an independent repair. This is not our case and requires knowledge of electronics to repair.

- Checking the remote control with a digital camera.

To do this, just point the remote control at the camera lens or cell phone camera and hold the button. At this point, take a picture of the remote control without the flash. If the remote control or button is working, then the photo will show a bright white spot in the place of the IR LED. If the glow is visible in the photo, then the reason is most likely in the receiver located in the TV or other equipment from which your remote control. Conclusion about the repair, as in the first paragraph.

- If they do not work, or work (respond to pressing) with 2-10 attempts, only a few buttons, the most frequently used, then this is our case. Next, we will consider ways to eliminate this malfunction of the remote control.

All remote controls have a similar device. Main components:

- Frame. Consists of two halves, glued or twisted.

- Printed circuit board. The board contains a small microcircuit, some more radioelements, an infrared LED, contacts of the battery compartment and a contact pad in the form of conductive tracks.

- Rubberized pad with buttons.

At the very beginning, we take out the batteries, then we look in the battery recess for the presence of fastening screws. They can be found under the stickers. Swipe over the sticker with a screwdriver, if it sells somewhere, then there is a screw under it. Examine the entire case for screws. If there is, unscrew everything and divide the case into two halves. In addition to the screws, the case can be latched. If there are no screws, then the whole case is assembled only with latches. It happens that it is additionally glued, but do not panic, everything is sorted out.

We take any knife and gently push the tip into the slot in the middle of the case and try to push the halves apart until a click appears. A click indicates that one of the latches has opened. It is important here to find and disengage the first latch, the rest will go easier. Try to do everything carefully so as not to break the latches, and even if you break one or two, it does not matter, the remote control will not close worse from this, in extreme cases it is easily glued with a drop of any superglue. You can also separate it with two thin screwdrivers, or combine a knife and a screwdriver.

If you are disassembling the remote control for the first time, it is preferable to work with a knife and a screwdriver. First, slip the tip of the screwdriver into the slot, 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, 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 the knife, you can insert a second screwdriver and continue moving with the tip of the knife, or continue moving with the first screwdriver. In general, do as you like.

Then take out the board and the rubber pad with buttons. The battery compartment has slots into which the spring contacts of the batteries are inserted. Before removing the printed circuit board, remember how they fit in the grooves so that there are no questions during assembly. In most cases, these contact springs are soldered onto the board and do not fit otherwise.

General remarks.

Before reconnecting the conductive layer of the buttons, it is recommended to simply clean it first. Sometimes contamination is visible with the naked eye.

Quite often, the entire space where the rubber base with buttons is located is filled with a transparent sticky and viscous liquid that looks like an epoxy resin, only without a hardener. This liquid is smeared with a neat thin layer, in places with small droplets. This sticky liquid is everywhere. On the top and bottom of the rubber base of the buttons, on the top of the case with sockets for buttons. The top of the PCB with contact pads is also smeared with this glue ...

The origin of this glue is a matter of debate and even controversy in repair circles. Some say that it is grease from the fingers, others that it is fumes from batteries. But why, then, the lower part of the board, where there are no parts, is not covered with these fumes?

The most likely version seems to be that these sticky compounds come from the very rubber base itself. The rubber seems to be sweating, releasing plasticizers from itself, which indicates a violation of the technology for the production of rubber products. The only question that arises is why there are so many such substandard products? This is observed in almost every remote control when such a malfunction occurs.

It should be cleaned with soap or other detergent, but not alcohol, acetone, etc., which can lead to a complete failure of the remote control.
A good result can be obtained by washing the board and gum with buttons with not very hot water, preferably with the use of dishwashing detergent or laundry soap.

Rinse gently with a soft cloth, dabbing with motions, so as not to erase the graphite coating.It is quite good if, before washing off the snotty deposits, the parts of the disassembled remote control lie for some time, about 20 ... 30 minutes, in a detergent solution. After rinsing, do not wipe it off, but wait until the parts are dry and only then assemble the remote control. You can use a hair dryer to speed up drying.

Do not completely assemble the remote control, put the buttons, insert the batteries and check the operation. If everything works, collect and use. If the malfunction remains, proceed to the second stage of recovery. In some cases, you can skip flushing and go straight to recovery. Intuition to help you.

Using glue, carefully glue the pieces of foil onto the pads of the "mat". Foil can be taken from sweets (clean), chocolates, or better from a pack of cigarettes. Aluminum foil with a paper base from cigarette packs is glued quite reliably and simply with any glue of the "Moment" type or superglue from small tubes. Piglets can be made both square and round. You can use a hole punch of a suitable diameter. The result should look something like this.

A 5-7 cm long strip of double-sided tape must be glued to the foil, cut off the edges of the foil where there is no tape. Then we “pass” the foil with adhesive tape through the hole punch as many times as we need to repair the buttons or use scissors. You can also use a broken telescopic antenna. A link of a suitable diameter is taken and circles are carved on the glass. When the circles are ready, glue them on the non-working areas of the remote control buttons. You don't have to bother with circles, but cut out squares.

Additionally, you can carefully use a sharp blade to cut the conductive rubber layer from the buttons in front of the sticker. Typically this is a layer of about 0.5-1.0 mm.

You will need a copper wire with a diameter of 0.2-0.4. Using a hammer, flatten it on any anvil with an interval of about 1 cm. Schematic designation (“——” This is a wire, “O” is a place for flattening) (—- O —- O —- O—-) we cut off the element (—– )

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

If fixed well, then this option is quite durable.

A simpler option is a metal staple bracket. Bend-shorten to the size of the contact pad and press it into the rubber in such a position that when the button is pressed, the bracket closes the contacts on the board.

Another option for repairing the remote control is to smear the buttons with conductive adhesives and varnishes, for example, "Kontaktol" or "Ellast". There are also many different opinions regarding this method, which is not yet clear better. Apparently, everything is simple: whoever succeeds well, he praises and vice versa.

Ready-made repair kits are sold specifically for repairing remote controls. They are cheap - the main thing is to find. The bag contains a tube of glue and round graphite-coated rubber patches. Just spread and glue where you need to. There are even instructions on how to glue.

A more modern version of the repair kit is self-adhesive patch. Everything is quite simple here. In such cases, it will not hurt to wipe the rubber buttons with alcohol or other solvent.

All options are functional and tested in practice. Choose whichever you like best. Good luck.

In the first part of the article, it was told about the history of the emergence and development of remote controls (RCUs) for controlling household television equipment.

Despite all the technological breakthroughs, the increase in the speed and the number of commands, the improvement in the design and noise immunity of the remote control are, perhaps, the most vulnerable node of television and video equipment. It is he who gradually or immediately stops working, perplexing the owners. Next, we will consider various typical malfunctions of remote controls and methods for their elimination.

The TV does not respond to any of the buttons on the remote control

Here the question immediately arises - what to do and who is to blame. It is undoubtedly necessary to start checking with what is simpler, namely with the remote control. First of all, you need to check if the remote control works at all. This is very easy to do. It is enough to bring the LED of the remote control to the camera lens, which is in any phone, and press any button. In this case, flashes of the remote control LED will be visible on the viewfinder screen. The color can be from white to bluish, everything seems to depend on the camera.

If these flashes are present, then we can assume that the remote control is almost operational. Pressing all buttons in turn allows you to test each button separately. Before doing this test, it is advisable to check the batteries. The easiest option is to replace the batteries with new ones or check the existing ones with a multimeter.

Checking batteries with a multimeter

The best way to do this is in the DC current measurement mode on the 10A range. At lower limits, it is possible to "blow" the 250mA fuse inside the device. Unlike rechargeable batteries, batteries are not afraid of short circuits, and if we manage to measure the current within 200..500mA, then everything is in order. It is better to check it separately for each battery, it is easier to hold it in your hands together with the test leads of the device.

If you measure the voltage on the batteries, then you need to load them, otherwise even unusable batteries can show the presence of voltage. In the process of checking - replacing the batteries, pay attention to the contact plates in the battery compartment. If oxide deposits or rust are found, the plates should be cleaned with sandpaper or even a small file.

To avoid scandals at home, the number of TVs must be at least two. This is the best option for checking a "suspicious" remote control. It’s probably known that remotes fit (or don’t fit) both home TVs.

If the batteries were changed, the camera was looked at, and there were no light pulses from this, then the remote control would have to be disassembled.

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.

Disassembling the remote control

All consoles are arranged and disassembled in a rather monotonous manner. The first thing to do is remove the batteries from the battery compartment. In the same compartment, carefully look if there are any fastening screws here, as a rule, this is their place. But often there may be no screws at all. In this case, you can start dividing the remote control into two halves.

For this, a suitable tool, such as a screwdriver, is inserted into the joint. Some descriptions of this procedure say that the screwdriver can leave traces in the form of chips and scratches. Therefore, it is safer in this regard to use a regular credit card, which are issued in immeasurable quantities in any "magnet" or "pair". The main thing is to get successfully to the first latch without breaking it, and then gradually and carefully open the rest.

After the remote control is open, the lower part can be put aside for now. The entire remote control will remain in the upper part. The remote control with the bottom cover removed is shown in Figure 1.

Figure 1. Remote control with cover removed

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

If, when checking with the camera, no signs of life were found, then you should immediately check the appearance of the LED and resonator, inspect their soldering. If they are oxidized or have ring cracks, then they must be re-soldered.It is better not just to pierce with a soldering iron, but to remove these parts from the board, clean and irradiate the leads, and only then put them back in place.

If you remove the PCB from the case, you will find a rubber base with buttons under it, as shown in Figure 2.

Figure 2. The buttons, when pressed, close the contact pads on the PCB.

The component side PCB is shown in Figure 3.

Figure 3. Remote controller board

Figure 3 shows the top of the rubber base with button pushers.

Figure 4. Upper part of the rubber base with pushers of the buttons of the remote control

When assembling the control panel, the mentioned pushers are inserted into the slots of the top cover (Figure 5), at the same time being the fixing element of the rubber base.

The pictures show everything quite decently and cleanly, since not long before that the console had undergone minor repairs. As a rule, any remote control opened for repair is a rather miserable and even heartbreaking sight.

What can be seen inside the remote control

The entire space where the rubber base with buttons is located is filled with a transparent sticky and viscous liquid that looks like an epoxy resin, only without hardener. This liquid is smeared with a neat thin layer, in places with small droplets. Even if you try, it won't work out so well and neatly right away.

This sticky liquid is everywhere. On the top and bottom of the rubber base of the buttons, on the top of the case with sockets for buttons. The top of the PCB with contact pads is also smeared with this glue ...

The origin of this glue is a matter of debate and even controversy in repair circles. Some say that it is grease from the fingers, others that it is fumes from batteries. But why, then, the lower part of the board, where there are no parts, is not covered with these fumes?

The most likely version seems to be that these sticky compounds come from the very rubber base itself. The rubber seems to be sweating, releasing plasticizers from itself, which indicates a violation of the technology for the production of rubber products. The only question that arises is why there are so many such substandard products? Indeed, in almost every remote control that gets into repair, just such a defect is noticed.

These evaporated plasticizers are most often the reason for the failure of the remote control. Outwardly, a similar defect manifests itself in the fact that the buttons stop "pressing", you have to increase the applied effort, but after a while this also does not lead to the passage of commands. You can press as hard as you like, for a long time, several times, but the channels do not switch, the volume is not regulated ...

Several repair methods

There are many recipes, advice and opinions on how to deal with this phenomenon. One source advises to immediately wipe all this disgrace with alcohol, gasoline or acetone, another says that in no case. Whom to believe? I will share my own limited experience in the field of remote control repair, there were not many clients, mainly relatives, neighbors and acquaintances, but the simplicity of the device and repair allows us to draw certain conclusions. And if you also listen to what is written on the Internet ...

Once cleaning such a remote control with alcohol led to its complete failure. If before cleaning only a few buttons (probably the most frequently used) worked poorly, then almost all of them stopped working. Therefore, I had to resort to another method of repair, but my memory was deposited that these buttons cannot be washed with alcohol.

A much better result, if the board has such a snotty look, can be obtained by washing the board and gum with buttons with not very hot water using a modern dishwashing detergent.It should be noted that here, too, you can overdo it: if you wash the rubber base with very vigorous movements and press harder, then the result can be exactly the opposite. The graphite coating from the buttons will be washed off, and you can then press them as much as you like, while not at all fearing that pressing the button will cause a channel change or volume control.

If the graphite coating has not been washed off before, then it should be washed with a soft cloth, with gentle, dabbing movements, which will never erase the graphite coating. The inside of the case and the PCB are best cleaned with a glass jar and bottle brush. It is quite good if, before washing off the snotty deposits, the parts of the disassembled remote control lie for some time, about 20 ... 30 minutes, in a detergent solution.

After washing, you should be patient, wait until the parts are dry, and only then assemble the remote control in the reverse order. If such a flushing gave a positive result, the remote control is working, you can only rejoice at the result. Otherwise, you can suggest several more repair methods.

What to do if buttons are worn to the ground

For these situations, solutions already exist: repair kits for repairing the remote control are being sold. The bag contains a tube of glue and round graphite-coated rubber patches. Just spread and glue where you need to. There are even instructions on how to glue. A more modern version of the repair kit is self-adhesive patch. Everything is quite simple here. In such cases, it will not hurt to wipe the rubber buttons with alcohol or other solvent.

But, unfortunately, it is not possible to buy such semi-finished products everywhere and not always, although the price of the issue is simply ridiculous: where are we and where is the radio market. In these cases, you have to use various improvised means. One of the best available materials is paper-backed aluminum foil from cigarette packs. It is glued quite reliably and simply with any glue of the "Moment" type or superglue from small tubes.

Another option for repairing the remote control is to smear the buttons with conductive adhesives and varnishes, for example, "Kontaktol" or "Ellast". There are also many different opinions regarding this method, which is not yet clear better. Apparently, everything is simple: whoever succeeds well, he praises and vice versa.

Of course, modern prices for remote controls are not high, and it's easier than inventing something, go and buy a new one. But it happens that the TV is so old that not a single modern remote control is suitable. Most likely it's time to buy a new TV along with the remote control. Or, nevertheless, to repair the old remote control.

Almost all modern household appliances have remote controls, so when this small device breaks down, users experience some discomfort. We will tell you how easy it is to repair the TV remote control at home with your own hands, without calling the master from the service. Many people just go to the store and buy a new remote control, but in the event of a slight breakdown, everything can be fixed by yourself.

The statistics of remote control repairs in service centers states that the most common breakdowns or device failures are as follows:

• breakdown of important controls and housing due to falls from different heights or other mechanical influences;
• sometimes some of the buttons do not work the console, and the rest perform their functions properly;
• frequently used buttons do not function or only work when pressed very hard;
• The TV's remote control works only from a very close distance.

It is not difficult to identify the cause, but you need to know the procedure for the upcoming repair, which directly depends on the breakdown that has occurred, sometimes it is cheaper to buy a new remote control than to revive the old one.

Important! When the remote control buttons for your TV do not work, before proceeding with the repair, try to insert new batteries - in 80% the remote control will work in the same mode.Such simple actions will help to reanimate even the Smart TV remote control.

In this section, we will tell you in detail how to disassemble and repair the TV remote control in each case.

When users often drop the TV remote control, serious breakdowns occur inside the device, and repairs in this case will be quite difficult - without a soldering iron, it will hardly be possible to restore the bounced solder. To make sure that the board is to blame, and you need to rewire something - there is original way of checking, you just need to make sure that the batteries are in working order. This method checks absolutely any remote control, regardless of its brand - Samsung, Philips or LG, because the principle of operation is identical for everyone.

In any digital camera and on mobile phones, including, there is infrared emitter, we check the TV remote control with it:

• turn on the camera on the mobile phone;
• direct the remote control to the camera window, while bringing the mobile phone as close as possible, press any key on the remote control;
• if the remote control emits a signal, a large red dot will appear on the device screen.

Its presence indicates that the board is working, and you just need to check all the buttons. If the point is absent - 100% something happened in the control board, you need to get it out and visually look for the cause of the breakdown.

We remove the batteries, then carefully and without effort we disconnect the halves of the remote control from the TV, after unscrewing the fastening screws. If the latches are installed, then we use a thin screwdriver, but without fanatical efforts, so as not to break their delicate design.

In this case, repair of the remote control can only be done by a person who has certain knowledge and skills in working with a soldering iron - it is better for an ordinary user not to fit into such a delicate device. As a result of frequent dropping, the LED mount may break off, the battery contact terminal may come off, or the quartz resonator may fail. The first two breakdowns can be identified visually. To make sure that the resonator - a small box with contacts soldered to it - is in good working order - you need to gently shake the entire device, if you hear a rustle, then you need to change it.

Users sometimes ask the question: how to repair the TV remote control when some buttons have stopped working. During operation, the inside of the TV remote control could get wet due to high humidity in the room or accidentally spilled drink. According to experts, a state of oil condensate has developed inside the product - the accumulated dust has combined with water vapor, which greatly complicates the correct operation of the buttons when pressed. Such a repair of the remote control buttons can be done on your own: special skills are not required here, you only need accuracy and patience to clean the device for controlling the TV.

1. We carefully disassemble the remote control.
2. We wipe the board with a cotton swab, soaked in alcohol - in such a simple way, the plaque of dirt and moisture, which can close the contacts, is removed. Efforts are not worth it - the product is quite delicate.
3. In the same way we wipe the contact rubber pads of the buttons.
4. We clean the spring contacts of the batteries, if there are traces of oxidation, then they are removed with a shallow sandpaper.
5. After cleaning, we give time to dry all the elements and assemble the device.

Note to users! Remotes made in China stop working after cleaning with alcohol! This is especially true for the Samsung model of the Chinese assembly.

To cleanse such delicate products from internal dirt, you must use soap and water - with the help of the solution, all the insides are gently wiped, then they must be washed with plain water at room temperature, wiped off with paper towels, and left to dry.After final drying, assemble the structure and check its functionality.

Repair of remotes, when frequently used buttons have worn off their contact bottom cover, is done at home. To do this, you will need the following materials:

• foil, which has a paper base on the back - this is necessary for high-quality gluing, a similar package from a cigarette pack is very suitable for this;
• good glue type "Moment»Or with a conductive silicone base.

In retail, there is a special glue for such needs, but it costs more than the remote control itself, which in our case is unprofitable for repairs.

The repair technique is simple.

1. We disassemble the remote control and remove the rubber part.
2. We glue foil circles or squares on the bottom surface of non-working buttons.

In stores you can find special kits, where there are buttons with a conductive coating and a very strong glue for attaching them. This kit can come in handy for repairs to restore your remote control.

If the TV remote control is broken because it was accidentally stepped on, then repairing it will cost you many times more than purchasing a new one. The market will pick up an exact copy of your remote control, even if you have a TV with Smart TV, which does not require any setup - insert the batteries and use it. Until the purchase is made, you can do with manual control: turning on the TV without a remote control is quite simple, but unlocking it is more difficult.

Experts assure that almost any user can perform minor repairs of any TV remote control: it is possible to replace batteries or stick new conductive spare wheels from a repair kit without having certain knowledge and skills. In case of complex breakdowns, you should contact the masters from the service, if the repair is more expensive than the remote control itself, then it is easier to purchase a new one.

We offer home craftsmen to watch this video, which clearly shows the repair of the remote control:

Probably, many of the readers have come across the repair of the remote control (doo) from the TV.

Quite often, the buttons on the remote control completely or partially fail. This malfunction can be caused by various reasons: bad batteries, dirty contacts, or breakdown of other elements.

If any problem occurs, it is better not to rush to throw away the product, but try to repair it yourself. Moreover, it is not always possible to find a high-quality remote control of the original model on sale, for example, a Samsung smart TV.

Quite often, the repair of the remote control depends on the type of breakdown, or rather, on the severity of the malfunction. In any case, whatever the malfunction, it can cause many problems.

But if you know the types of breakdowns, then they can be easily eliminated with your own hands.

In most cases, there are several types of remote control breakdowns:

• frequent falls that could lead to failure of quartz and important elements; there may be no reaction to certain keys, but when you press others, this is not observed; lack of work for frequently pressed buttons; sometimes you have to push hard to make the buttons work; the remote control works, but only at close range.

But identifying the reasons is still half the battle; you need to know the repair procedure. Therefore, it is worth considering a detailed troubleshooting procedure. The complexity of the repair directly depends on the type of breakdown.

Due to frequent falls of the device, quite serious breakdowns can occur, the repair of which will have certain difficulties. This is due to the fact that the connections in the solders on the circuit are often broken.

If everything is in order with the batteries, then the remote control can be checked using a cell phone camera. Since an infrared emitter is installed in it, capable of detecting any interference.

This procedure should be performed according to the following scheme:

1. The first step is to turn on the cell phone camera.
2. We direct the remote control to the camera. We bring the camera close enough and press any button on the remote control.
3. If there is a signal from the remote control, a thick red dot should appear on the phone screen.

But sometimes this signal may not be there. In this case, the device must be disassembled and the board removed. Next, you need to carefully look at this board and make the necessary repairs.

It is necessary to disassemble the device with special care - it is important not to break the body of the product. The first step is to take out the batteries, examine the area where they were bookmarked. If there are screws, then they are unscrewed.

If the device has latches, then it can be disassembled with a thin-pointed screwdriver or a plastic card. To do this, a screwdriver or card must be inserted into the hole located at the top and bottom.

Repair can be done by someone who knows how to work with a soldering iron. Quite often, as a result of frequent drops, the LED may fall off, and the contact pads of the batteries may come off or the quartz-type resonator may be damaged.

You also need to shake the board and listen. If there is a rustle, then this may be the reason for the breakdown of the quartz resonator.

Next, you need to remove this element (it looks like a small soldered box). Then it changes to a new one. It can be purchased at any radio store, as well as in the online radio parts store.

Sometimes breakdown can occur due to strong pollution, dust getting inside. Do not forget that a malfunction may occur due to tea, water spilled on it, or due to an increased level of humidity in the room.

In these situations, a condition of oil condensation occurs inside the device. The elimination of these breakdowns can be done independently.

The repair procedure should be carried out according to the following scheme:

1. The remote control is disassembled. The board is wiped with a cotton swab dipped in alcohol. Due to this, the board is cleared of plaque.
2. You also need to wipe the contact pads of the buttons on the rubber part. You can clean the case. But it is not advisable to rub hard, otherwise important contacts can be damaged.
3. Separately, it is worth cleaning the spring contact. If the contamination of the element is too strong, then to clean it, use sandpaper and wipe with a sponge with a hard base.
4. After cleaning and drying, all parts must be put back together.

Yes, indeed, Chinese models can completely break down after this treatment. Therefore, to eliminate these consequences, prepare a solution of soap and water.

Then a sponge is dipped in there, and all contaminated parts are wiped off. After that, all parts with a soapy solution are cleaned with cool water, wiped with a paper towel and left to dry completely. At the end, the console is assembled.

Sometimes certain buttons on older appliances wear out due to frequent use. It is not even the buttons themselves that are erased, but the conductive spraying, and the remote control does not react when these buttons are pressed.

In these situations, you can easily make your own remote control. For repair, you will need the following elements:

• foil, it is imperative that there is a paper base on one side;
• silicone-based glue or Moment glue. There are also adhesive mixtures with a conductive base.

How to fix the problem yourself:

1. 1. First of all, we disassemble the device and take out the rubber part.
   2. Foil paper is glued to the back of the buttons. Foil from cigarettes or chocolates is perfect.

1. 1. We glue the foil with the paper part of the silicone mixture or the Moment glue.

1. There is also a special conductive glue for gluing, but its cost is quite high.
2. On sale there are kits with glue and spray buttons. These kits can easily be used to repair the remote control yourself.In the area where the old buttons with attrition were located, you just need to glue the new ones.

If the remote control finally breaks down and any attempts to repair it with your own hands did not lead to the desired result, then it will have to be replaced with a new one. Moreover, you can find similar products on sale that do not need to be specially tuned for your TV.

Do-it-yourself remote control repair is not such a difficult process. Sometimes you can simply replace the batteries and the remote control will resume in the same mode. However, batteries may not always be the cause of product malfunction.

Perhaps the breakdown was caused by other consequences. In any case, if everything is done according to the instructions, then the malfunction can be easily eliminated by yourself.

From this video You will learn how to repair a TV remote control with your own hands:
