DIY repair

In detail: do-it-yourself repair of a remote control from a real master for the site my.housecope.com.

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 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.

Video (click to play).

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 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 ...

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 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.

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.

The most common defect, unintentionally incorporated into the design by the manufacturers of remote controls, is (judging by the personal practice of repairing the remote control) poor contact of the “positive” and “negative” terminals with the power supply. Made of an alloy not quite suitable for such devices, they bend easily and lose their former elasticity in operation (especially after the expiration of the warranty period). Violation of the springiness of these terminals can be eliminated quickly and permanently by placing a non-rigid rubber (for example, a stationery eraser) between them and the end of the board, which will securely press the contacts to the batteries.

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

Another common malfunction is when the most running buttons stop working, or work, but only with increased pressure.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 over the old, worn out conductive contacts on a rubber base.

And the printed circuit board must be carefully cleaned of the viscous liquid released with a dry soft cloth. Graphite contacts are easy to repair with a “soft” crayon pencil.

Attention. Contrary to the practice common among radio amateurs, in no case should you wipe the graphite contacts on the printed circuit board with alcohol, cologne (and even more so with solvents). Alcohol-containing substances and solvents break down graphite.

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

If the TV normally responds to commands from the remote control, it means that the board of the latter is working properly, and you only need to change the rubber with buttons.

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

It happens that it is not possible to buy new tires. However, you should not despair - you need to restore the old one. It is necessary to separate the black contact plates from all buttons on the back of the rubber mat. Then, with any glue for rubber, glue new ones on the vacated places. You can find workable contact plates in many older electronic devices recognized for other reasons as unusable: calculators, keyboards , push-button telephones, etc.

The 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 with a blade, making sure that the thickness of the plates does not exceed 1 mm (otherwise the remote control buttons will be constantly “pressed”).

How to disassemble the remote control

First, the remote control must be disassembled. Despite the different sizes and appearance, all remotes are essentially the same.

We take out the batteries and at the same time look at the fastening screws in the battery compartment, which may be under the factory stickers. Use a screwdriver to forcefully over the sticker, if it sags, then there is a screw under it.

In modern consoles, screws may not be at all. In this case, you can immediately start disassembling the remote control.

The body of the remote control consists of two halves that are connected to each other either with screws or latches, or using both methods. To separate the halves of the remote control, a suitable tool, for example, a knife, is inserted into the joint seam. We carefully push 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 can leave traces 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 immeasurable 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 does not matter, the remote control will not close worse because of this: it is checked. You can also separate it with two thin screwdrivers, or combine a knife and a screwdriver, as you like.

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

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

If you look closely at the board from the side of the tracks and the rubber base from the side of the contacts, you can see that in places they are, as it were, smeared with a thick layer of adhesive mass. It's fat. Because of this fatty layer, poor contact is obtained between the graphics coating of the board and the contacts of the rubber base, which is why you have to press the buttons with force for the remote to carry out our commands.

Take a sponge for washing dishes, lather with soap, and wipe off the grease from the board, rubber base and halves of the remote control case. Then wash off the soapy foam under running warm water. Wash off grease only with soap suds and nothing else.

Now all the elements must be wiped dry and additionally dried with a hairdryer, or put on a hot coil in the bathroom for thirty minutes through a thin layer of cloth.
Gather your "little friend" and sitting in an armchair, switching channels, enjoy his work, and at the same time yours. As a rule, after such a prophylaxis, the control panel starts working as new.

If it doesn't help, go to plan B

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

Method # 1 Foil punch and double-sided tape. ( No special glue or 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),

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 the buttons we need to repair. Actually ready-made circles and stick them on 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.From the foil, cut small squares to fit the size of the rubber pad's contact pads. Alternatively, instead of foil, use foil paper, for example, from cigarettes. By the way, I tried to use it, it was enough for about six months. Let's see how long the foil lasts.

Superglue and foil squares

Using glue, carefully glue the pieces of foil onto the pads of the "mat". It should look something like this.

Let the glue dry and reassemble the remote. Everything should work.

Video instructions for repairing the remote control in this way

We take an old keyboard from a computer, take a metal tube, sharpen the edges to sharpness and knock out holes with spots on the film. We glue them onto the contact pads of the “rug” of the remote control using a suitable glue - not a single repetition in three years.

This method of repairing the remote control is called in the forehead.

There are more sophisticated ways, such as this method of repairing the remote control:

“One volumetric part 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 add about two parts by volume of gasoline, the vessel is immediately closed and shaken vigorously. The silicone glue must mix completely with the gasoline to form a homogeneous milky mass. After that, one to two parts by volume of graphite powder is added to the mixture, and it is again strongly shaken. If the solution is too thick, it can be diluted with gasoline again.
The “old” contact pads of the rubber mat are cleaned with an ink (red) eraser or fine sandpaper, the remnants of 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 sheet of paper and then apply a drop of the solution to the conductive surface. Due to surface tension, a slight but noticeable swelling should occur. After the mortar has set, 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 be stationary. ”

What do you need:

we take a copper wire size 0.2-0.4, flatten it with a hammer and a ratchet head (well, a wrench) with an interval of about 1 cm, you should get something like that,

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

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

the same option from a different angle

What do you need:

We take an unnecessary cable from the FDD or HDD and take out the contacts from there, then it is clear.
You can try to make a type of 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 clearer.

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 ceramic resonator... Here are the contacts of the battery compartment and the only electrolytic capacitor for the entire panel.

If all of the above methods did not help, you can try to additionally walk the soldering iron over its electronic components in order to eliminate possible leakages, especially with regard to 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, and as soon as the tin begins to melt, remove the soldering iron tip. Do not solder only the pins of the microcircuit, you can overheat it or short-circuit the pins and tracks with solder. Usually microcircuits rarely fail. But if it so happens that it is necessary to solder the microcircuit, be extremely careful, and at the end, be sure to check the leads and tracks so that no drops of solder remain between them.

Now we can say with full confidence that the remote control you repaired will work for a long time. Thus, almost all remote controls are reanimated.

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.

We carefully disassemble the remote control.
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.
In the same way we wipe the contact rubber pads of the buttons.
We clean the spring contacts of the batteries, if there are traces of oxidation, then they are removed with a shallow sandpaper.
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.

We disassemble the remote control and remove the rubber part.
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:
