In one of the articles we looked at the question of how to unlock an Android phone if you forgot your graphic password.

The possibilities of a modern smartphone are limitless. Almost any technical task, whether we are doing complex computational work, or simply want to “teach” a gadget new capabilities, can be solved with a few taps on the screen. Let's talk about how you can control your TV using an Android mobile gadget. This may be necessary if the original remote control has failed and there is no way to quickly replace it.

Not so long ago, in order to turn on the TV from a smartphone, you had to have special technical knowledge, but now it is enough to install a special Android application. The TV must have certain functions that can be used to establish a connection between the TV and the smartphone:

• Smart TV. Allows you to connect to your TV via Wi-Fi
• IR port
• Bluetooth module

The corresponding modules must be installed in the phone.

Large manufacturers such as LG, Panasonic or Samsung develop applications specifically for their models. We will look at universal programs for Android that turn a smartphone into a remote control for various TV models.

Assembling the attachment for the IR remote control

Installing the application

Laziness is the engine of progress. Following this expression, the remote control (RC) appeared. Quite a large amount of modern technology cannot be imagined without its use. On the devices themselves, the number of control buttons is reduced, and sometimes they are completely absent.

All control is transferred to the remote control! A typical representative of such technology is the television. Branded remote controls are usually an order of magnitude higher in quality than their counterparts, but they are also more expensive.

Therefore, such a skill as how to repair a TV remote control with your own hands will not only save money, but also the time required to search for and possibly adapt it.

The principle of operation of the remote control (RC) is a simple action - pressing a button. Each button is responsible for its own operation. Pressing it causes the remote to send out an infrared light signal, which is received by the device's receiver.

Any remote control, regardless of form and functionality, consists of the following elements:

1. Housing made of durable plastic.
2. Electronics boards.
3. Keyboard matrix (buttons).
4. Batteries.

The electronics board consists of a set of electronic parts inherent in any remote control:

• keyboard controller chip;
• output transistor stage;
• crystal oscillator;
• emitting infrared diode (there may be more than one).

On PCB special places are located, when pressed through the button, the tracks are closed. The microcontroller processes this press and, using part of the circuitry, the chip determines which button was pressed, generating a sequence of characters. The sequence for each press is unique and constitutes the so-called code.

A digital code is sent by the device in the form of a specific flash frequency. Every flash is sequence of short pulses. The duration of short pulses forms a unique code.

In this way, a logical zero or one is formed. Used to transmit commands frequency modulated signal, lying in the infrared spectrum. The operation of the chip is supported by a quartz clock generator. Its reference frequency is approximately two hundred and fifty kilohertz.

Main breakdowns and their causes

The device itself is highly reliable. Frequent breakdowns occur due to careless handling. Basically these are various falls, contamination, liquid ingress, and the use of low-quality power supplies.

The most common defect is in violation of contact power supply battery with remote control. This contact is a spring-loaded terminal into which the batteries are inserted.

Violation of the springiness of the terminals is eliminated by additional bending plates or stretching springs, and in case of oxidation - by cleaning the contacts. Cleaning is carried out using mechanical treatment, for example, sandpaper and wiping with an alcohol solution applied to a swab or rag.

The next most common malfunction is deterioration of contact graphite printed board elements with buttons. This is expressed in the form of a complete failure of the button or a change in its parameters.

The button has a conductive rubber at its base. When it degrades, caused by both external and technological reasons, an oily substance is released, which prevents contact. To troubleshoot a problem it is usually enough to simply rinse with alcohol solution polluted places.

If the conductive rubber loses conductivity, then in such cases it will be impossible to restore it yourself and you will have to buy new buttons or use a repair kit for remote controls.

The kit contains conductive circles and glue that will need to be glued over old, worn-out rubber-based conductive contacts. To do this you will have to disassemble the remote control. How to disassemble the remote control for TVs Lg, Samsung, Panasonic or another well-known brand, we will consider below.

Before you repair the TV remote control yourself, you need to make sure that it’s the problem. If the device has an LED, then based on its operation we can conclude that it is working properly, although not all remote controls have such an indicator and its presence is even rare.

You can get accurate information about performance by using any video lens. The properties of a video lens are that it registers an infrared signal. To do this, point the remote control at the lens and press the buttons. If flashes appear in the viewfinder, the remote control is working. No - it will have to be repaired.

First, if the device malfunctions, you must change the power element, if this does not help, proceed with further disassembly. Let's consider, for example, how to disassemble the Philips TV remote control and repair it. Everything that will be said is also true for other brands of remote controls.

Philips TV remote control

As mentioned above, all control panels are designed the same. The remote control body is structurally made of two halves, which are connected to each other by latches and screws. First, remove the batteries and examine the battery compartment for screws.

They can be either obvious or hidden under stickers. Unscrew all the screws, if any, in the compartment and along the contour of the remote control. Since they are small, they can get lost, so it is better to immediately put them in any container.

At the junction of the two halves, with a little force, insert a stationery knife or an unnecessary plastic card. It is better to start from the place where the screw was screwed in. We pass along the entire perimeter of the connection, trying to push the halves apart, there should be characteristic clicks indicating the removal of the latches.

This operation requires skill, so a number of latches may break, but do not worry too much about this. When the halves are separated, we will immediately have access to the board. Carefully remove it and the rubber base, as well as tinted glass covering the infrared diode.

Exploring the insides of the remote control

Having gained access to parts of the television remote control, you can immediately determine why it stopped working. So, if the buttons stop switching or simply begin to work poorly, then we clean the contact pads on the board and, if necessary, replace the rubber conductive circles on the base.

Attentively inspect the paths for corrosion, for example due to liquid ingress. If there is a damaged area, then carefully clean it and restore it using a thin wire and a soldering iron. This operation requires certain training and skill. If visually everything is normal, we try to replace the infrared diode by re-soldering.

If it so happens that after these actions it was not possible to revive the remote control, then you will have to carry out major repair of electronics board. This will require a certain level of training and the ability to use electronic devices such as a multimeter and oscilloscope. You will need to check quartz generation, information signals on the chip, and the performance of transistors and capacitors. If this is not difficult, then the repair will probably be successful.

After completing the replacement or restoration of faulty parts we assemble the remote control in reverse order. The buttons should be pressed easily, with little force. We insert the batteries and check their functionality.

Modern houses are like a gallery of various types of household appliances. And almost every device has its own remote control. It’s not strange that sometimes you can get lost in the “collection” of remote controls and not understand what’s what. And in general, ideally it would be to replace them all with one remote control. But I don’t really want to shell out a tidy sum for such a device. And there is no need to throw money away. From this video tutorial you will learn how to make a universal remote control with your own hands.

Training video “How to make a universal remote control with your own hands”

Anyone can make a remote control for any equipment with their own hands. You don’t have to be a super physicist to do this – just follow the detailed instructions. But before we describe step by step how to make a universal remote control, here is one interesting fact.

Anyone who still remembers what mobile phones were like 10 years ago knows that many models were then equipped with an infrared port. It was used to transfer information (media files). But then it didn’t work out to use it as an element of the remote control. Now mobile phone manufacturers have again begun to supplement gadgets with infrared emitters. They give the smartphone another function - use as a remote control for home electronics.

Meanwhile, you don’t have to buy a new expensive smart remote control, because a similar device can be obtained from any Android phone.

For this you will need:

• smartphone;
• infrared diodes - 2 pieces (which are used in the TV remote control);
• glue;
• sandpaper;
• 3.2 mm plug;
• soldering iron

1. To begin, use sandpaper to carefully grind off the sides of the infrared diodes. Stitch on one side only.
2. Use a small amount of superglue to connect the two elements. Wait until the glue dries.
3. Carefully bend the legs of the LEDs and cut off the excess. Using a soldering iron, combine the anode of one LED with the cathode of the second. Using the same scheme, solder the remaining cathode and anode.
4. Next, solder an infrared diode to the left and right legs of the plug. In this case, the polarity does not matter.
5. To strengthen and protect the joint, fill the joint with glue (you can use a heat gun). Place heat shrink on top.
6. Install the finished device into the headphone jack.

By following these simple steps, your smartphone can be used as a universal remote control. But before that, to completely transform the smart phone, you still need to install a special program. You can easily download it from the play store. There are several similar applications. And now your Android can control the operation of your TV, microwave, and even your camera.

We didn’t fully understand how to create this super gadget based on a smartphone - watch the video tutorial, it explains in detail and shows what and how to do.

The TV remote doesn't work: how to repair it yourself

In many ways, the repair, or rather, its complexity, depends on the type of breakdown. Sometimes it’s enough just to clean the remote control from dirt with your own hands, and in some cases you need to solder something.

A very common situation is when you press the remote control buttons and nothing happens: the TV doesn’t work, the channels don’t change, the sound doesn’t change. That is, the TV does not react in any way to manipulations with the remote control, there is no connection between them. This can happen if:

1. the batteries are completely dead;
2. The remote control fell to the floor multiple times.

With the first situation, everything is clear - you need to install a new battery, and this will complete the repair. Even a child can repair the device in this way.

In the second case, the situation is more complicated. Most likely, connections have been broken in some soldering joints on the circuit. If the batteries are fine, there is one simple way to check the operation of the remote control before you disassemble it.

• Turn on your mobile phone camera.
• Point the remote at the camera as if you were taking a photo and press any button on the remote.
• If there is a signal from the remote control, but on the mobile screen you will see a thick glowing dot.

If there is no signal, then the remote control will have to be disassembled, the board examined and a full repair made. You need to disassemble it carefully so as not to scratch or break the body, and this is not always easy. First, take out the batteries and inspect the niche for them. If there are screws, unscrew them; if the remote control is latched, then carefully open it using a thin screwdriver or a hard plastic card, inserting it into the gap between the top and bottom parts.

To get a good look at the board and see the fault, you can use a magnifying glass. DIY repairs can be done by anyone who knows how to use a soldering iron. Most often, the LED falls off, the contact pads of the batteries come off, or the quartz resonator is damaged.

Shake the board and listen. If a rustling sound is heard, then the quartz resonator is cracked inside and will need to be replaced. It looks like a small soldered box. Its cost on the radio market is low.

Some buttons press and work, and some don't work

It happens that the remote control is very dirty, juice has been spilled on it, or there is simply high humidity in the room and oil condensation has formed inside. In such a situation, DIY repairs are not too difficult.

• The remote control must be disassembled and the board wiped, removing plaque from it. To do this, use a cotton swab soaked in alcohol.
• In the same way, they wipe the contact pads of the keys on the rubber part, as well as the body, so that it is pleasant to hold in your hands. Do not rub too hard to avoid damaging the contacts.

There are reviews that after drinking alcohol, the remote control does not work at all. Chinese flimsy analogues can really break. If you are afraid of this turn of events, you can use plain water and dishwashing detergent. Make a soapy solution, dip a soft sponge into it and wipe all the parts with it. Then rinse under gentle running water, pat dry with a soft cloth and leave to dry.

Separately, you need to clean the spring contact. In case of severe contamination, you can use sandpaper or wipe them with a hard sponge. When all the parts are dry, they are assembled together. As a result, you repaired the remote control with your own hands.

Some buttons on old remotes simply wear out due to frequent use. To be more precise, the conductive coating wears off, and the remote control does not work when you press the worn keys. In this case, you can also repair the old remote control. And it’s not difficult to do it yourself.

Open the remote and take the rubber part. On the back of the buttons you need to stick thin foil, for example, from a chocolate bar, with paper on one side and metal foil on the other. It must be glued with silicone glue, or “moment” type glue.

Conductive glue is available, which provides more reliable contact, but it costs much more.

Kits with glue and sprayed buttons are also sold. They are specifically designed for remote control repairs. In place of the old, worn down buttons, you just need to stick new ones.

A permanently broken or lost remote control must be replaced. Buy a universal remote control device in the store and use it to your health. If you wish, you can find a remote control that is completely similar to yours, then you won’t even need to configure it specially.

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 a TV remote control at home with your own hands, without calling a service technician. Many people simply go to the store and buy a new remote control. but in case of a minor breakdown, you can fix everything yourself.

Statistics on remote control repairs in service centers claim that the most common breakdowns or failures of devices look like this:

• failure of important controls and housing due to falls from various heights or other mechanical influences;
• Sometimes some buttons don't work remote control, and the rest perform their functions properly;
• Frequently used buttons do not function or only work when pressed very hard;
• The TV remote control only works from a very close distance.

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

Important! When the remote control buttons for your TV do not work, before starting repairs, try inserting new batteries - in 80% of cases the remote control will work as before . Such simple steps will help to revive even the Smart TV remote control.

In this section we will describe in detail how to disassemble and repair the TV remote control in each specific case.

When users often drop a TV remote control, serious damage occurs inside the device; repairs in this case will be quite difficult - without a soldering iron, it is unlikely that it will be possible to restore the soldering that has come off. To make sure that the board is at fault and you need to resolder something - there is original way to check. You just need to make sure that the batteries are in working condition. This method is used to check absolutely any remote control, regardless of its brand - Samsung, Philips or LG, because the principle of operation is identical for all.

Any digital camera, including mobile phones, has infrared emitter. we check the TV remote control using it:

• turn on the camera on your mobile phone;
• point the remote control at the camera window, while holding the mobile phone as close as possible and pressing any key on the remote control;
• If the remote control produces a signal, a large red dot will appear on the device screen.

Its presence shows that the board is working, and you just need to check all the buttons. If the dot is missing, then 100% something has happened in the control board, you need to take it out and visually look for the cause of the breakdown.

We remove the batteries, then carefully and effortlessly separate the halves of the remote control from the TV, having first unscrewed the fastening screws. If latches are installed, then we use a thin screwdriver, but without fanatical efforts, so as not to break their delicate structure.

Advice! To carefully inspect the board, use a powerful paw; do not rely on your visual acuity - some defects cannot be recognized without repeated magnification.

Repairing the remote control in this case 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 get into such a delicate device. As a result of frequent falls, the LED mount may break off, the battery terminal may come off, or the quartz resonator may fail.

The first two failures can be determined visually. To make sure that the resonator - a small box with contacts soldered to it - is in good working order, you need to carefully shake the entire device; if you hear a rustling sound, then it needs to be changed. Users sometimes ask the question: how to repair the TV remote control when some buttons stop working. During operation, inside the TV remote control could moisture gets in

1. due to high humidity in the room or an accidentally spilled drink. As experts say, a state of oil condensation has arisen inside the product - accumulated dust has combined with water vapor, which greatly complicates the proper operation of the buttons when pressed. You can do this kind of repair of remote control buttons yourself: no special skills are required here, you only need accuracy and patience to clean the TV control device.
2. Carefully disassemble the remote control. Wipe the board with a cotton swab, soaked in alcohol
3. - this simple method removes deposits of dirt and moisture that can short the contacts. There is no need to put in any effort - the product is quite delicate.
4. 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 remove them with fine .
5. sandpaper

After cleaning, we give time for all elements to dry and assemble the device.

Note to users! Remote controls made in China stop working after cleaning with alcohol! This is especially true for Chinese-assembled Samsung models. To clean such delicate products from internal dirt, you need to use soap and water

- using the solution, carefully wipe all the insides, then wash them with plain water at room temperature, wipe with paper napkins, and leave to dry. After final drying, assemble the structure and check its functionality.

• Repair of remote controls, when frequently used buttons have worn off their contact bottom coating, is carried out at home. For this you will need the following materials:. which has a paper base on the back side - this is necessary for high-quality gluing; similar packaging 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 circles or squares of foil onto the bottom surface of the non-working buttons.

You can find it in stores special sets. where there are buttons with conductive coating and very strong glue for attaching them. This kit may be useful for repairs to restore your remote control.

If the TV remote control breaks because it was accidentally stepped on, then repairing it will cost you many times more than purchasing a new one.

The market will find an exact copy of your remote control for you, even if you have a Smart TV. which does not require any setup - insert batteries and use. Until the purchase is completed, you can get by with manual control: turning on the TV without a remote control is quite simple, but unlocking it is more difficult.

Experts assure that minor repairs to any TV remote control can be performed by almost any user: replacing batteries or gluing on new conductive spare parts from a repair kit can be done even without specific knowledge and skills. In case of complex breakdowns, you should contact the service technicians; if the repair is more expensive than the remote control itself, then it is easier to purchase a new one.

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

Sometimes you may encounter a situation where the buttons on the television remote control stop pressing. This situation is considered common and therefore you need to repair the remote control. There can be many reasons for its failure. The main reason is mechanical damage. The technology for repairing it is not difficult.

If the buttons on your TV remote don't work, then first of all you will need to check the batteries on your device. If you do not see any changes, then you need to turn on the flash on your phone and point it at the diode on the front of the remote control. This diode should light up when the buttons are pressed. This must be done only using a phone, since a person will not be able to notice the infrared radiation.

If you do not see results, then in order to repair the TV remote control with your own hands you will need to disassemble it. Disassembling the remote control is quite simple. To do this, you simply need to unscrew all the screws on the device. There may be several of them, and they may be hidden. After unscrewing all the screws, you should insert a screwdriver at the junction of the remote control housing.

Sometimes you can also find remote control models that are attached using latches. To disassemble it, you simply need to disconnect the housing. After disassembling the case, you should look at these parts:

• Electrical board.
• Button contacts.
• Contacts for batteries.
• Emitting diode.
• Ceramic quartz.

These are the main parts that make up the design of the remote control. In order to repair the remote control, you should inspect all its parts.

First of all, you need to inspect the contacts on the batteries. If it is unsoldered, then it will need to be carefully soldered. You also need to look at the spring that is in contact with the battery. If it gets dirty, then it needs to be cleaned. This can be done using sandpaper. If your vacuum cleaner has poor suction. then read how to repair it.

The next cause of failure may be dirty button contacts. This dirt may form as a result of prolonged use of the appliance. Oil condensation from the skin on your hands may settle on the device. In order to avoid this problem, you must use a protective film for the remote control.

If dirt has formed, you can remove it using napkins and alcohol. Sometimes dirt can short circuit the contacts and cause the buttons on the TV remote control to not work.

If the contacts are coated with graphite, then the problem may be that they have worn off over time. In this case, repairing the TV remote control will be quite simple. You need to take some foil and stick it on the contacts. Also, a fairly common cause of breakdown can be the breakdown of ceramic quartz. If the remote control does not work due to a breakdown, then the problem lies in this element. You can easily determine this damage yourself. To do this, you need to shake the remote control and you will hear a slight rustling sound.

If it is possible to turn on the TV only from a close distance, then the cause of the breakdown is dead batteries. The last malfunction of the remote control includes damage to the contact tracks. If you see a crack on the microcircuit, then repairing the remote control is inappropriate in this case. In this case, you need to buy a new device. If the speakers on your computer don't work. then you should study the cause of the breakdown.

What do you need to know when repairing your remote control?

If the buttons on the TV remote control do not work, then you can repair it by purchasing a simple repair kit for the remote control. It has a high price, but can last several times.

With its help, you no longer need to deal with gluing “patch marks”. Also, if the buttons on your device are stuck, then you need to clean it. In this case, grease will not be able to get onto the contacts.

Do-it-yourself TV remote control repair: photo troubleshooting instructions

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

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

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

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 coating, and the remote control does not react when you press these buttons.

Repair the remote control

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

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

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

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

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

So, let's begin.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Good luck to you!

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

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

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

If the remote control is rare, then a photograph of the board from both sides, with sufficient clarity to see all the details, is highly desirable. It’s better to immediately write the backstory - it fell, water got in... And what they themselves did to make it work.

If your remote has stopped working after being dropped, replace the crystal first, and then check the rest of the circuit. It is he who most often suffers as a result of a fall. Main don't start scientific research — just replace the quartz with the same one.
