The button on the remote control works how to fix it. Fix the remote control. What can be the malfunctions

Despite tremendous progress, in modern world any device is susceptible to damage. But we can safely say that most often those devices that we use constantly fail. The remote control for the TV belongs to this category.

Several billion people around the world use the TV remote control multiple times every day. Unsurprisingly, these devices fail so often. Fortunately, you can repair this device yourself. Fortunately, the process does not require any serious skills.

The remote is completely unresponsive

As a rule, the complexity of the repair mainly depends on the type of breakdown. While in some cases it is possible to do with ordinary cleaning, in others it will be necessary to use soldering devices. But do not despair - repairs can be easily done with your own hands.

One of the most common problems is the lack of reaction of the TV to pressing the buttons on the remote control. In this case, the main feature is that all the buttons do not react at all. There can be two reasons for this:

The battery has run out.
The remote control was frequently subjected to mechanical stress (for example, falling to the floor).

The first step is to replace the batteries. If the TV remote control works and all buttons respond to pressing, then the repair is over. With an unsuccessful outcome you will have to repair the device yourself or buy a new one.

If, after replacing the batteries, the buttons do not respond, then the connection in the product is lost somewhere. As a rule, this happens at the contacts of the circuit. You can immediately start disassembling and repairing the remote control from the TV, but it is better to check the signal first. To do this, you need to do the following:

Turn on the camera on the smartphone.
Aim the infrared LED of the remote control (the light that is located on top of the device) at the smartphone's camera.
Press any button on the remote control and at the same time look at the smartphone display.

If there is a signal, a luminous dot will be shown on the screen. If not, then you need to start a full repair. As stated above, this process is very simple and you can do it yourself. Nevertheless, the repair of the TV must be carried out in a certain sequence.

Remove the batteries from the device.
Examine the battery niche.
If there are screws in the niche of the remote control for the TV, then you need to unscrew them. If not, disassemble the remote using a thin screwdriver that needs to be inserted into the latch between the top and bottom of the device.
Examine the board carefully. Usually, the contacts of the LED, the pads for the batteries or the quartz resonator depart from it. In this case, you will need a soldering iron for DIY repair. Necessary gently solder the contacts with the device board.
If everything is in order with the contacts, you need to shake the board. If, after shaking, a small rustle is heard, then it is necessary to replace the quartz resonator (a small soldered box). The cost of this element on the radio market is very small. It is necessary to install using soldering.

The process is pretty straightforward. However, if you are unsure, you can watch the repair video.

There is a reaction only to a few clicks

The cause of this malfunction is a large accumulation of dust in the device. Therefore, it will not be necessary to repair, but to clean the remote control. It is also recommended to act in a specific order:

Before such repairs, it is worth making sure that the remote control does not stop working after cleaning. To do this, you need to see if the brand on the device matches the one indicated on the TV. If the company names on the remote control and the TV are the same, you can proceed with the above cleaning.

The fact is that many Chinese analogs of remote controls do not withstand alcohol and fail. Therefore, if your remote control belongs to such products, it is necessary to use dish detergent instead of alcohol. Also, instead of a cotton swab, it is better to do with a soft sponge.

No response to frequently used buttons

The more often a device is used, the more likely it is to break. It's the same here: constant pressing of the same buttons causes them to wear out. Or rather, the conductive sputtering disappears, due to the absence of which the remote control stops working.

The instructions for solving such a problem are also very simple.

Take out the batteries and disassemble the remote control.
Pick up the rubber part of the device.
On the back of this component, where the buttons are notched, you need to stick on small pieces of foil... The main thing is that the foil is with paper (for example, from a chocolate bar). It is necessary to glue it with silicone or special conductive glue.
Allow the device to dry.
Assemble the remote control back.

Repair of the television remote control is not particularly difficult. It does not require any special skills or special tools. The main thing is to be careful and take your time.

In most cases, the repair is successful and the device starts working again. However, in especially difficult cases, all efforts to restore are in vain. The easiest and most effective way out in such a situation is to buy a new remote control.

Probably, everyone in the house has at least one household appliance with a remote control. remote control... This is a very convenient thing, and, as you know, you quickly get used to comfort. But consoles, like everything else in the world, sometimes fail. It is usually difficult to find the exact same remote control, so you have to buy a universal programmable remote control. Such remotes are massive, you have to get used to the button layout again. Therefore, we will tell you how to fix the remote control yourself, because repairing remote controls is not at all difficult.

Typical problems with remote controls:

Some buttons do not work or do not work.
The remote control does not work at all.
Contacts in the battery compartment are oxidized.
Sometimes the buttons stick, the reason for this is the dirt that accumulates under the case during use.

The most difficult part of repairing remote controls is to disassemble the case. You don't need to have any skills in electronics, and you don't have to worry about safety either.

Tools and materials for repairing the console

digital camera or mobile phone with camera
Phillips and flathead screwdrivers

magnifier or microscope

Console repair technologists

1. Check the batteries, if they are dead, replace with new ones. After changing the batteries, check the operation of the remote control, for this you need a digital camera or a mobile phone with a camera. Aim the camera lens at the infrared emitting diode and press the buttons alternately. You should see a flashing diode on the camera display. If the diode does not respond, it is burned out. Don't be discouraged and move on to the next step.

2. Disassemble the console case. If the housing parts are connected with screws, unscrew them. Sometimes the screws can be hidden under a sticker or rubber inserts. Most often, there are no screws on the case, and its parts are connected using plastic clips. Finding the clips and carefully opening the remote control is quite difficult, so you have to try. Use a thin, non-sharp object, such as a small flat-blade screwdriver, to bend the clips.

3. You should have on hand a digital camera with which you checked the operation of the infrared diode. Therefore, it is advisable to take a photo of the remote control with an open case, so that later the parts can be easier to install in place.

4. Disassemble the remote control into parts, after taking a photo of the location of the buttons (often the keyboard is a solid rubber plate with buttons, in which case you do not need to remember the location of the buttons). Fold all the small parts into a box.

5. Carefully inspect the board and check the integrity of the soldered connections. Remotes are often dropped, so the board may crack or the solder connections may be damaged. Inspect the board in good light, you can use a magnifying glass or microscope. Solder all suspicious connections. If there are signs of oxidation on the board, clean it with a toothbrush and denatured alcohol. If the board is dirty, you can wash it in soapy water, rinse well and dry it with a hair dryer. We do not recommend this procedure with boards mobile phones, since they have elements that cannot be in contact with water.

6. Rinse body parts and buttons. Take a small bowl and put all the parts of the remote control in it. Pour in warm water and dishwashing detergent. If the dirt is difficult to clean, leave the parts in the detergent solution overnight.

7. Rinse the parts thoroughly under running water. To prevent small parts from falling into the sink, place them in a colander or plug the sink drain. Wipe the parts dry with a paper towel.

8. If the case or buttons of the remote control are damaged, they need to be repaired. Cracks can be repaired with hot glue or super glue. Let it dry. Reinsert the buttons. You can get rid of scratches and chips on the case by heating it with a hair dryer (do not use burners for this, the plastic may catch fire). If the infrared diode in the remote control burns out, you can replace it with an emitter from any other unnecessary remote control or buy a new one on the radio market. Observe the polarity when replacing the diode.

9. Check the operation of the remote control using a digital camera. Press each button in turn and see if the diode is on. If the diode responds to every press, then you managed to repair the remote control.

Everyone is familiar with the TV remote control today. And everyone knows that over time, something will happen to the remote control. What to do, if the buttons on the TV remote do not work and how to put the remote in order - read the article.

Change the battery

If your remote has not been broken in half or into more parts, but its performance leaves much to be desired, then the first thing you should definitely do is change the batteries. No matter how trite it may seem, many people often forget about it. As a rule, AA and AAA batteries are used in TV remotes, both of which are popularly called "finger" batteries. Small ones are sometimes called "little fingers".

If the old batteries have not been replaced for a long time, this could lead to the leakage of electrolyte from them and to the oxidation of the contacts of the batteries. So when changing batteries, make sure there is no oxide or rust on the contacts. If there are any, then you should clean them off with a sharp knife.

Buttons on the remote control do not work - at all

If it's not about the batteries, then you should check the buttons, namely, press everything. If the TV does not react at all to pressing the buttons, then the matter is bad and then 2 options arise either the remote control is completely out of order or the problem is in the TV receiver.

The development and cheapening of technologies today have led to the fact that, in the overwhelming majority of cases, it is cheaper to buy a new remote control than to repair and dig with an old remote control. But if the purchase of a new remote control did not solve the problem with controlling the TV and it does not respond to any of the buttons, then there is already a problem in the TV itself.

Buttons on the remote control do not work - some are bad

If the buttons on the remote control do not work for you, but not all, but only some, or you have to make a lot of effort to activate them, then most likely the problem lies in the dirt that got inside the remote control. In this case, disassemble and wash the remote control.

The most common cause of the remote control not working is spilled sweet tea, coffee or soda. Sugar dissolved in drinks forms a sticky film on surfaces that prevents the buttons from pressing, acting as an insulator.

How to clean your TV remote

We remove the batteries and unscrew all the screws, if any. Often the screws can be hidden under some stickers, rubber feet, or in the battery compartment. Next, we pick up all the plastic latches in a circle. We act carefully, without violent actions - they easily break down.

Taking off back cover remote control and getting to the insides we withdraw the board. It can be held by screws. If you look at the board, you can see wet streaks on its surface. We will launder them.

Under the board is the keyboard rubber band, which can be split into two. The elastic is also smeared with some kind of obscurity, so we will wash it too.

The principle of operation of these buttons is very simple - there are two closed contacts on the board. These black patterns are the contacts. If you look closely, they are scallops entering each other.

On the elastic band, on the inner side of the buttons, there are closing circles. These circles, when pressed, close the contacts on the board with each other. So the remote control recognizes the press, and then transmits the command to the TV. It springs the button solely due to its shape and the fact that it is made of rubber.

In fact, these buttons are open design and, as a result, any ingress of dirt between the board contacts and the closing pad inevitably leads to better response.

How to wash the remote control

Having disassembled the remote control, we separate all the plastic and rubber parts and go to the bathroom, where we thoroughly rub the remote control body with a soapy brush, and then thoroughly rinse it from the soap residues.

Elastic bands should be treated more gently. The part of which they close the contacts of the board is a conductive material deposited on a rubber base. Do not rub them with a brush. Better to rub gently with soapy hands or just rinse under warm water

We send the washed parts of the remote control to dry on your favorite towel. It is advisable to keep the towel clean. You can also wipe it off, but again, do not rub the conductive places on the elastic bands.

We clean the remote control board from dirt

In the meantime, the whole thing is drying up, let's start cleaning the board.In general, I prefer to use pure alcohol for such purposes - it evaporates quickly, leaves no residue and dissolves any dirt well.

But its last property should be treated with caution, because it is not known whether the material of the contacts on the board will withstand the effects of alcohol. So far, I have not seen cases of contacts being dissolved with alcohol, but just in case, I always try on less important buttons first.

EU whether you still have doubts, you can use a pharmacy alcohol, a concentration of 70%, or use wet wipes. In this case, after wiping off the dirt, remove the remaining moisture with a paper towel. And it's better not to rub, but just apply.

After washing, the contacts acquire a uniform matte black color, and the board loses indistinct streaks and becomes monochromatic.

Actually, at this point, washing the remote control came to an end. Before assembling, make sure that there is no moisture on the component parts.We assemble the remote control and are surprised at how easy it is to press its buttons.

Now you know what to do in a situation when the buttons on the TV remote control do not work and how to wash the TV remote control with your own hands. And if you have any doubts, you can watch a clear short video. Wish you success!

DIY TV remote control repair.
It has already become customary in our house to have a color TV controlled by a remote control. And after a certain time of use, we began to notice that the remote control began to work differently than before.
How it began to manifest itself:
- Reducing the range.
- When you press individual buttons, they do not work the first time, but only after a few clicks.
- Some buttons stopped working at all.
- Not a single button works.
- When changing batteries, they drain quickly.
- Operation from the remote control when moving it slightly away from the direction of the TV.
To identify the reason for the poor performance of the remote control, it is most correct to do a few simple steps.
1. Check the contacts of the battery compartment.
Clean the contacts from possible plaque, try rotating the inserted batteries in the compartment.
2. Replace the batteries with new ones if the voltage drops significantly.
3. Disassemble the remote control, removing the housing covers, must be done with extreme caution, so as not to break the plastic clips that secure the covers.
After disassembling the case, inspect the printed circuit board and determine
what needs to be done to repair the remote control:
1. Can be applied to the conductive layer of graphite with a pencil.
2. Stick on the conductive rubber graphite pads using the repair kit.
or
3. Wash off dirt, grease from the surface ...

In the photo there is a repair kit for remote controls and a photo of the printed circuit board of the remote control TV SONY BRAVIA.
So what is the best way to choose how to fix the remote control?
1 METHOD. If you apply a conductive layer to the conductive surface of the buttons by rubbing the shaft of a simple pencil. Not a bad way, but you need to know where to apply the layer so as not to make it worse, as an extra conductive path will appear, which will not improve the condition of the remote control. And also take into account that this track (lead) will crumble over time and the remote control will again require attention, it will have to be repaired again.
Advice: there is no need to apply a lead to all buttons, first of all apply to those buttons of the remote control that do not work well, because usually the volume buttons, the numbers of the buttons of your favorite channels, etc. are affected more often.
2 METHOD. Stick the repair buttons from the set on the conductive places. This method seems simple, but do not rush, it requires a lot of attention and accuracy. It may be necessary to bite off the upper surface of the button a little with pliers to reduce its thickness, because when gluing the repair circles, they can interfere.

3 METHOD. Clean the surface of the board and the rubber pad with buttons from grease and dirt. Most often, it is good enough to clean and degrease the board with tracks and the inside of the silicone pad and the remote works fine again.
Be careful when cleaning: do not clean the conductive layer of the button on the silicone pad and the conductive layer on the tracks of the PCB to shine - otherwise the remote control will not work at all !!!
When cleaning the board, gently wash around the conductive pads and tracks, but if they have grease, etc., then gently wash without removing the conductive layer.

In the first part of the article, it was told to control 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. Various typical malfunctions 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 rather monotonously. 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 no signs of life were found when checking with the camera, then check immediately appearance 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.

Figure 5.

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 bring washing the board and the rubber bands with buttons are 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 will be washed off from the buttons, and then you can 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 are 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.
