How to repair the connections of the boiler. How to independently operate the TV remote control

Of course, every person in the booth will have at least one everyday device with a remote control. This is a very clear voice, and as you know, it sounds very comfortable. All remote controls, like everything else in the world, sometimes go wrong. If you know the remote control itself, you will have to buy universal remote control programming. Such remote controls are massive, and you have to press them again before the keys can be moved. That's why we know that fixing the remote control with your own hands, even repairing remote controls, is not at all difficult.

Typical problems with remote controls:

• The buttons do not press or operate.
• The remote control doesn't work at all.
• The contacts of the battery pack have oxidized.
• Sometimes the buttons stick, which is caused by debris that accumulates under the body during operation.

The easiest way to repair remote control panels is to remove the housing. There is no need for advanced knowledge in electronics, and you don’t have to worry too much about safety equipment.

Tools and materials for remote control repair

• digital camera or mobile phone with camera
• khrestova and plane twists
• small capacity
• drushlyak
• denatured alcohol
• home for dishware
• paper towels
• soldering iron with solder
• magnifier and microscope

Remote control repair technologies

1. Check the batteries, if they stink, replace them with new ones. After changing the batteries, check the functionality of the remote control, for which you need a digital camera or a mobile phone with a camera. Point the camera lens at the infrared LED, which is visible, and then press the buttons. It is your responsibility to display the LED flashing on the camera display. If the voltage does not respond, it will burn out. Don't rush and go until the end of the day.

2. Disassemble the remote control housing. If the parts of the body are connected by screws, unscrew them. Some screws can be stored under a sticker or gum inserts. Most often there are no screws on the body, so the parts are connected using plastic fasteners. Finding the lock and carefully opening the remote control is difficult, so you have to try. To remove the fasteners, use a thin, non-sharp object, for example, a small flat screwdriver.

3. You have a digital camera in your hand, with which you have verified the feasibility of the infrared diode. It is therefore important to take a photo of the remote control with the open case, so that later the parts can be easier to install in place.

4. Take the remote control into parts, first taking a photo of the arrangement of the buttons (often the keyboard is a solid gum plate with buttons, in this case there is no need to remember the arrangement of the buttons). Place all other parts in a box.

5. Carefully inspect the board and check the integrity of the solder connections. Remote controls often fall, which can cause the board to crack or the solder connections to become damaged. Look at the cost of good illumination, you can quickly use a magnifying glass or a microscope. Solder all suspected connections. If the board shows signs of oxidation, clean it with a toothbrush and denatured alcohol. If the board is clogged, you can wash it in warm water, rinse thoroughly and dry with a hairdryer. This procedure is not recommended for mobile phone boards, since they contain elements that cannot come into contact with water.

6. Wash the parts of the body and buttons. Take a small bowl and place all parts of the remote control next to it. Pour warm water from the dishwashing liquid into it. Since it’s important to remember, fill in the details of the matter at hand.

7. Rinse the parts thoroughly under running water. To prevent other parts from falling into the bowl, place them in a bowl or close the drainage hole with a stopper. Wipe the parts dry with a paper towel.

8. Either the housing or the buttons of the remote control are damaged and must be repaired. Cracks can be filled with hot glue or superglue. Let the youma dry. Insert the buttons on the seat. You can get rid of rips and dents on the body by heating it with a hairdryer (do not use a hair dryer to do this, the plastic may burn off). Since the infrared LED in the remote control has burned out, you can replace it with another unnecessary remote control or buy a new one for the radio market. When replacing the diode, ensure correct polarity.

9. Convert the usefulness of the remote control with a digital camera. Next, press the skin button and watch the light light up. If the LED reacts to pressure on the skin, then you will need to repair the remote control.

Lin is the engine of progress. Inheriting this system, the remote control (RC) will appear. A great deal of modern technology cannot be discovered without its use. On the devices themselves, the number of control buttons changes, and it happens that they are the same every day.

Everything is transferred to the remote control! A typical representative of such technology is a television. Branded remotes cost an order of magnitude more for the battery than their analogues, but at the price they cost more.

Therefore, by repairing the TV remote control with your own hands, you can not only save your finances, but also the time necessary for searching for and possible adaptation.

The operating principle of remote control (RC) is based on a simple action - a pressed button. The skin button indicates its operation. Pressing the remote control to strengthen the infrared light signal, which rejects the device.

Regardless of the form and functionality, any DC remote control depends on the following elements:

1. The body is made from high quality plastic.
2. Pay electronically.
3. Keyboard matrix (buttons).
4. Life batteries.

The electronics board consists of a set of electronic parts that power any remote control:

• keyboard controller chip;
• output transistor stage;
• quartz oscillator;
• viprominent infrared diode (maybe more than one).

On another board expanded special places When you press a button, the tracks will freeze. The microcontroller collects the pressure and for other parts of the chip circuitry it determines which button was pressed, generating a sequence of characters. The sequence for skin pressure is unique and is called the code.

The digital code is strengthened by the device to visualize the singing frequency of the spalahs. Kozhen slept - tse sequence of short pulses. The frequency of short pulses forms a unique code.

This is how a logical zero or one is formed. To send commands you need to sign up frequency modulation signal, which lies in the infrared spectrum. The operation of the chip is supported by a clock quartz oscillator. Its reference frequency is approximately two hundred and fifty kilohertz.

Main breakdowns and their causes

The device itself is characterized by high reliability. Parts of the breakdown are due to a number of reasons. Mainly a serious decline, obstruction, loss of life, stagnation of unclear life resources.

The widest defect lies at broken contact living battery with remote control. This contact has spring terminals into which life elements are inserted.

Damage to the spring tension of the terminals is tightened by the additional way tightening the plates or stretching the springs, and in case of oxidation – cleaning of contacts. Cleaning is carried out using mechanical cleaning, for example, with an emery paper and rubbing with alcohol, applied to a swab or gancher.

The attack on the widening of the problem is loss of contact Graphite laminated payment elements with buttons. This is reflected in the new appearance of the working buttons and changing parameters.

The button is structurally located at its base and has a flume-conducting gum. With its degradation, caused by both external and technological reasons, there is a strong reaction that passes through contact. To resolve the malfunction, simply call drink alcohol congested place.

Since the power supply loses its conductivity, then in such situations it will be impossible to restore it on your own and you will have to buy new buttons or quickly get a repair kit for the remote control.

A set of glassware, mugs and glue, etc. will need to be glued on top of the old, humic-based gum-conducting contacts that have become unsuitable. Why do you need to remove the remote control? How to use the remote control for TVs Lg, Samsung, Panasonic and other popular brands is discussed below.

Before you repair the TV remote control with your own hands, you need to check that everything on the right is new. Since the device has a light-emitting diode, it can be used to determine its status, although not all remote controls have such an indicator and its presence is rare.

How can you remove information about efficiency? vikorist whatever video lens. The power of the video lens lies in the fact that it registers the infrared signal. To do this, we point the remote control at the lens and press the buttons. As for the video monitors, there are sleepers and a working remote control. No - it will have to be repaired.

If the device malfunctions, it is necessary to remember the living element, which did not help to proceed to further sorting out. Let's look, for example, at how to remove the remote control for a Philips TV and repair it. Everything that will be said is also true for other brands of remote controls.

Philips TV remote control

As it was designated above, all control panels are powered again. The remote control body is constructed from two halves, which are connected to each other by clamps and screws. Now remove the batteries and check the battery case for screws.

The stench can be either obvious or visible under the sticker. We tighten all screws, because there is a stink, it is behind the remote control circuit. Since the stinks are small, they can be ruined, so it’s better to immediately remove them if they have any capacity.

At the point where the two halves are connected, a small stationery cutter is inserted into the unneeded plastic card. It’s better to start from that place, where the screw was twisted. We walk along the entire perimeter of the junction, soak up the halves In case of guilt there is a typical clattering sound, which means that the bolts have been removed.

This operation requires a beginner, so a number of screws can get dirty, otherwise you won’t have to worry about it. If the halves are separated, we are immediately denied access until payment. Neatly we know the humic basis, as well as a darkened side that covers the infrared diode.

Investigation of the interior of the remote control

Having lost access to parts of the TV remote control, you can immediately see why you have stopped working. So, since the buttons stopped murmuring or simply began to work badly, then the contact pads on the board and at the same time need to be replaced by the gum conductor heads on the stand.

Respectfully looking around the paths Prevent their corrosion, for example, through soiling. If the area is damaged, it should be carefully cleaned and refurbished using a fine-tipped soldering iron. This operation will require extensive preparation and attention. Since everything is visually normal, we are trying to replace the infrared diode with a re-soldering line.

If it so happened that after these actions it was not possible to resuscitate the MPC, then it would be necessary to carry out Serious repair of electronics board. For this you need a certain amount of preparation and use of electronic devices, such as a multimeter and oscilloscope. It is necessary to check the generation of quartz, information signals on the chips, the usefulness of transistors and capacitors. If there are no difficult things to do, then the repair will be very successful.

After completion, replace or renew defective parts selecting the remote control at the gate sequence. The buttons are pressed easily, with little force. We insert the batteries and check the functionality.

I.Ivanov

You can check the functionality of the remote control without a TV using an additional photodiode (PD) in the infrared range. Let’s go, for example, with the FD-8K. The PD pins are connected to the ground and signal probes of the oscillograph. The remote control remains in its orderly condition with the FD until the end. Press a button on the remote control. In this case, a PWM signal with an amplitude of 0.2...0.5 St. will appear on the oscilloscope screen.

Most television MPC schemes, however, include:
-microcircuit-formulator of commands with a quartz resonator;
- a booster that consists of one or two transistors;
- LED (or two);
- keyboard and contact field.

In addition, in all MDCs there is an indicator LED that registers the command.

Let's take a look at the possible malfunctions of the remote control, the methods for identifying them and correcting them.

1. No signal from MPC

They begin to open the remote control from the side by removing the batteries, and then push one side of the bottom cover to the entrance window, and then do the same, after which the cover can be easily removed.

An external look at the structure of the board and the keyboard contacts.

Traces of dried liquid on the contact area are wiped with a cotton swab soaked in alcohol. The wires of the conductors wear out the jumper from a thin dart.

Check the presence of contact between graphite jumpers and other conductors.

Having closed a pair of contacts on the other board, check with an oscilloscope the presence of a PWM signal at the cathode of the LED.

If there is no signal, and the constant voltage is equal to zero, check the LED. A reference LED has a few tens of ohms in the direct line, and a few hundred kilo-ohms in the reverse direction. A faulty LED must be replaced.

Part of the defect is the loss of the LED output as a result of a mechanical leak, for example, after the remote control is dropped.

Check the passage of the PWM signal from the output of the microcircuit to the LED.

2. No signal at the output of the PDK microcircuit

First check the voltage of the microcircuits: it may be no less than 2.5 Art.

The usefulness of the quartz resonator is verified by the additional short circuit of any pair of contacts on the other board. If there is no generation at all, then the microcircuit is most likely faulty.

3. There is no signal from the maximum permissible concentration. At the output of the microcircuit, the signal is

The oscilloscope checks the presence of the signal at the cathode of the LED. If there is no signal, check its passage from the output of the microcircuit to the light-emitting diode.

The most common defects in this case are failure of the transistor of the output stage of the booster, broken solders, and defective elements of the booster.

4. There is no signal from the maximum permissible concentration. The photodiode shows the presence of a constant voltage level. The batteries are running low. The LED is constantly open and a significant stream flows through it

The correctness of the transistors and the presence of closed contacts are verified by “checking”. The integrity of the microcircuits is checked by replacement.

5. From the remote control, the command for the unpressed keyboard buttons is constantly sent. Shvidko batteries are running low

Carefully rinse the microcircuit parts with alcohol, drying out any traces of rosin, saw, or brood. On the other board, use a cotton swab soaked in alcohol to wipe the contacts. Additional microcircuits are supplied from the board. If you follow this command from the MDC, you can continue to change the microcircuit. If the signal is lost, search for the current flow from the graphite jumper to the other conductor. The conductor is cut off from both sides and instead of it, a jumper from the isolated dart is installed.

6. One or more MPC buttons do not work

Use a multimeter to measure the contact points. The reference buttons have the same 2...5 kOhm. If the number is more than 10 com, the button is faulty. In this case, I will either change the gum completely or repair the contact. We sell special repair kits for MPC. Their stock includes rubber contacts that need to be wired, which are glued to the faulty keyboard contacts with silicone glue, which is included in the repair kit.

The presence of cracks is determined visually. Defective Drukarsky conductors are in favor of an additional switch from a thin dart.

Most current MPCs have the ability to process them from the service console. The essence of the rework lies in the installation of a new or rearrangement of the jumper that is on the other board, and the installation location on the board is indicated.

Like a butt on the tiny readings of the RM-836 remote control for SONY TVs with the top cover removed. After installing a jumper at pos. 1

The functional assignment of the button to change the image format is changed.

Now, after repeatedly pressing this button, the TV will be transferred from operating mode to service mode.

Repair of remote control panels.

After a number of accidents, the functioning of the remote control (RC) of TVs and other equipment is often disrupted. This is possible for a number of reasons: damage to the integrity of solder joints of electronic components, oxidation of the spring contacts of a battery pack, external or frequent abrasion of the conductive ball applied to the ends of the buttons (Fig. 1),

Those who are most often vikorists.

To eliminate the remaining defect, a simple method is proposed that undergoes verification through several steps and requires a lot of effort. For cleansing and degreasing, for example, with alcohol, at the end of the button, the practicality of which must be emphasized, apply one ball of glue to allow it to dry quickly, for example, “Second”, and then glue a piece of aluminum foil the size of a third more, lower area of ​​the end of the button. After the glue has hardened, carefully squeeze the foil that sticks out with tweezers (Fig. 2).

Practice has shown the high reliability and harmless operation of remote controls repaired in this manner.

If you have to repair remote controls frequently, you can prepare a device to monitor their effectiveness, collecting from available parts (Fig. 3).

The DA1 microcircuit serves to amplify the signal that comes from the infrared photodiode VD1, and forms the sequence of output pulses that goes to the DD1.1. When you press any button on the reference remote control, the VD2 LED flashes at a frequency of a few hertz. The device must be manually installed in a housing measuring 100x40x30 mm (Fig. 4).

The DA1 microcircuit can be replaced with manufactured analogues KR1054UІ1, KR1054ХА3, KR1056UP1, KR1084UІ1 with a different pinout rating.

As long as he properly mixes the channels, the artist is content with his life, one might say, beautiful. The button is pressed one more time, but the channel still does not mix. Trouble has come - open the gate. It's hard to find such buttons. What is the situation in which to work and clearly further?

Just because the remote control does not change its functions does not mean that it is faulty. The probability of breakdown of its filling under normal operating modes is close to zero, since its elements correspond to specifications. Therefore, the malfunction of the remote control is simply a fact, which is confirmed by the expanded expression: electrical engineering is the science of contacts. First of all, you need to check the battery terminals. It’s not surprising, but they themselves often reveal the reason. The impulses of the cheruban contribute to the strum of singing power.

There is enough ale, so that at contacts that have oxidized, “plant” the voltage on the microcircuits. As a result, the correct signal cannot be generated, and the TV cannot be switched. As a matter of fact, beware of frequently discharging electrical components. Since the remote control does not interrupt when you press a button, you first need to open the cover of the battery compartment. They can either be removed and reinserted, or, without being caught, snatched and twisted here and there on their own axis.

The oxide of the melt collapses and the contact is renewed. If after this operation the remote control works normally, it means that the target has been achieved. This drop is like a bell that anticipates the need to quickly replace the batteries. We are sorry to say that since there are two or more batteries in the remote control, they are discharged differently. For this purpose, however, it is recommended to periodically change them. And when replacing it with a tester, measure the short circuit and remove the old battery, replace it with a new one.

Let's disassemble the remote control - verification will continue

Well, the batteries are disturbed, over-checked, and stink. But the remote control still doesn’t mix. This time we check the buttons and the LED. Some remote controls are disabled. There are also models where the light LED is visible behind a dark glass. No matter how crazy you are, your robot won’t be able to control it with an unbroken eye. It vibrates light pulses in the IR range, which is beyond the human eye. All the video cameras that capture them are subject to optical transformation. The operation of the remote control LED can be improved and verified with their help.

According to the idea, if it is dark, a closed light-emitting diode may cause your sleep. Apart from their significance, as it seems, for the sake of the purity of the experiment, it would be better to revise it completely. For this, as well as to check the buttons, the remote control needs to be reset. The design of the remote controls varies. Therefore, you need to carefully look at the remote control that is being repaired before you unlock it. For manufacturability, the design must be formed on the surface with clamps.

Ale in these models can buti metalovirobi. Call for smells from aesthetic products that are available in a battery pack. However, having looked at the remote control, the droplets of self-tapping screws were not visible, which means that the Vikonan fastening is no longer on the clamps. In this case, two parts of the remote control housing need to be disconnected. For this, the seam is probed with the sharp tip of a knife. To insert it, I report a small amount of effort to twist, and remove the offended parts.

How to update buttons

If you work close to the wedges, the offended parts will become separated. With this final infusion of the seam the remote control is opened. In the middle there is a board covered with gum buttons. The LED is completely depleted, and the fragments will have to be soldered off for checking. And before doing this, we check the buttons. It is only possible to predict an LED malfunction based on the surface of an inappropriate remote control. If only one button works, it means the LED is defective, but the problem again is in the contacts.

The remote controls are easy to handle structurally. There are tracks on the other board. The contact is made with a gum-conducting ball applied to the surface of the gum button. When pressed, this ball falls on two side tracks, closing them. As the world grows more and more, the ball groans and loses the necessary power. Plus, there is so much obstruction on the surface of the paths. Especially since the TV was installed in the kitchen.

After 5–10 operations, the remote control may be affected by clogged contacts. For cleaning, you will need either special cleaning instruments for monitoring office equipment, or a cotton swab and alcohol. When cleaning the board and buttons, it is recommended to use polyethylene gloves. Wipe all surfaces that come into contact with a sanitary swab or cleaning cloths. If the remote control has been processed for five years or more, it is recommended to restore the buttons after cleaning.

Otherwise, all the same, it will be necessary to earn money. Please note with renewed effectiveness after cleaning. The sawing on the buttons is incredibly boring. It is best to apply a new ball when you first disassemble the remote control. A little bit of superglue and a piece of foil glued to the skin button will become a normal replacement for the original. While the glue is not hardened, the foil must be pressed to the surface of the button so that the foil sticks out more when pressed.

Quartz also wears out

Mostly there are buttons - this is the reason why you need to use the remote control. Or it may be that after gluing the foil, the efficiency does not reappear. This means that the reason may be in the electronic components of the electronic board. The damage is, as a rule, mechanical due to those who threw the remote control for a reason. The quartz resonator suffers from this. In the middle of this, irrevocable damage may occur.

It is important to determine the effectiveness of the remote control using the oscilloscope. If the remote control detects strong impacts, the quartz in the middle may fly off. When the remote control is shaken, there will be a slight movement in the middle of the resonator body. Quit - just replace with new ones. Moreover, replacing it again may not help. If the impact was strong enough to damage the resonator, the circuit board tracks could crack. This eliminates the most difficult operation of stopping and checking the LED.

Renovation completed

Carefully, holding one leg with pliers (so as not to overheat), you can eat it for free. To check the required tester in the vibration mode, support. It would be good if there is a red or other colored LED, so that you can move along the light until it is confirmed. Since the control LED emits light, as can be seen, the IR LED will also be visible through the video camera (you can use your smartphone).

If the IR LED is in good condition, the version about cracks in the tracks will be removed. Make sure that they are not visible if they are covered with a dry coating. He will have to use sharp probes to pierce him. By testing the skin in this way, you can detect damage. If a faulty track has been detected, the probes will not blink briefly, which will be visible on the tester’s display. It is necessary to remove the dry ball from it and, more often than not, find the crack.

Whose place on the road is to avoid spikes in thin tissues. Since the remote control still doesn’t work, you need to use an oscilloscope and look at the signals, which are in the main payment areas. Ale tse, swedish, under the power of specialists. And it’s easier for the average person to buy a new remote control.

How to repair the remote control Do-it-yourself remote bathing - this is often the problem with household appliances. I tried to grab as many of them as I had at home and I found 8 of them. Televisions, music centers, DVD players, VCRs, receivers for satellite television, air conditioners, chandeliers are all controlled by remote controls. As long as you make a noise and as long as the hand lever breaks, we become hopeless. First thoughts, why the remote control doesn’t work, how to repair the remote control how to earn money I’ll give the remote control back to the employees, so please use the remote control. If it appears, you can get the remote control with your own hands. Remote control malfunctions are usually easy to repair.

How to repair the remote control

For the beginning it is necessary to switch over, so that the remote control is broken, and not the device is damaged. Yak zrobiti? Read more and more...

How to check the remote control

A mobile phone with a camera function, a camera or a video camera is required. This function is already available on all phones, except for the simplest ones.

• We enter this mode on the phone,
• take our remote control and check it out
• directed towards the camera
• We press one button.

If you use the remote control, you must display on the phone screen, as the LED at the end burns out when you press the button. To reassure yourself that you did everything correctly, try to marvel at the working remote control in the same way. We've over-converted, there are no sleeping bags, and the remote control is broken. There are malfunctions of the remote control if, for example, they fail without pressing the button, which means that some button is stuck or there is damage on its contacts. How to repair the remote control due to such a malfunction, read below. And now we’ll remember about the batteries, as we’ve been victorious for a long time, checking their integrity. Batteries for powering remote control panels are used for a long time and may begin to leak. How can I fix a remote control with such a problem? It is always best to clean the rusty deposits with a knife to clean metal and wash the contacts with alcohol. If there is any doubt about the usefulness of the batteries, you can remove them from the working remote control for checking. Since the remote control also does not work, we move on to the next stage of repairing the remote control with your own hands. For what purpose is it necessary to rozіbrat.

How to open the remote control

Open the cover of the battery compartment and remove the batteries. Carefully look at the back surface of the remote control for screws. Often screw the battery case. I’ll change my collections remote to gwents, If the mounting of the remote control panels on the clips is much wider, you won’t find any screws on them. It is necessary to open such a remote control carefully so as not to damage your hands or the mounting bracket. Using a screwdriver with a wide end, which fits well into the groove between the upper and lower parts of the remote control, gradually remove the fasteners, tightening the lower part of the remote control and, without much force, moving it along the body. The remote control folds up

• The board contains a microcircuit, quartz, a vibrating diode, button contact plates, wire tracks and spring contacts for batteries.
• Gumovy kilimka with jet-conducting heels
• The front and rear panels are made from transparent plastic

Main problems with remote controls

1. Do not operate the buttons on the remote control.
2. One or more remote control buttons do not work
3. To be careful, you need to press hard on the remote control buttons
4. The remote control hums when you're close
5. The remote control sometimes works, sometimes doesn’t work

How to repair the remote control with a power hand.

The main reason why the buttons on the remote control do not work is that the contacts of the buttons are blocked. Brud can choose to freeze the contacts of the buttons, or else it will freeze them. And the algorithm of the remote control is such that if you press too many buttons at once, the command from the remote control is blocked and the remote control does not work at all. Therefore, it is necessary to clean the contact pads on the board and clean the contact pads on the gum squeegee. There are two types of contact patches on the buttons. With graphite filings and with jet-conducting gum. The graphite filing is gradually erased and removes traces on the contact plates of the payment, causing them to clog and shorten. As luck would have it, you have a remote control with gum that needs to be carried out, but here problems with waste and oxides soon appear. The contact pads on the board can also be made of different types, either graphite filings or copper conductors. Often, when you open the remote control, there is an oily residue on the board, which condenses the fat from the skin of your hands. If you have been using the remote control for a long time, this product will already be in a dry appearance on the buttons and body of the beast. If you need to forcefully press the buttons, so that the remote control is pressed, the nasty stench is pressed, it is 100% obstructed! Once you take the remote control apart, you will understand what I am talking about. I have a clean photo in the photo, but I will replace the photo later so that it can be seen better. How can you repair the remote control with your own hands in such a hassle? If the buttons are without graphite filing, they will help with cleaning. Here you need:

• a hard pencil with an old toothbrush,
• miyuchy zasib,
• alcohol
• school eraser

We clean the board with a cotton swab soaked in alcohol and bittersweet, do not stagnate the cologne, the stench will be removed from the melt and it will become even worse. The gum keyboard and body are lifted from the water, vikoryst, and the liquid is removed from the fat and crust an old toothbrush . Good sushimo. Using an eraser, we go over the gum spots on the gum squeegee and the contacts on the board. We collect and check the remote control. Wow, it’s wonderful! Website " How to earn money with your own hands "helped you.

How to create remote controls with graphite filings on the contact update buttons is described below.

How to repair the remote control with your own hands for other malfunctions

Since the remote control does not work, then in order to operate the remote control, you will need some knowledge of electronics and soldering.

The remote control works for an hour.

We check the soldering of the contact springs under the batteries on the board and the place of soldering of the high voltage diode. Carefully inspect and solder defective soldering.

The remote control stopped working after the crash.

I want to get ahead, sharp blows are not safe for them, the ceramic quartz on the board is very loud. To use the remote control, you need to replace it.

The remote control hums when you're close

It is possible that the batteries need to be replaced or the voltage supply is low. We first check the batteries by replacing them, and if the result is satisfactory, we change the voltage diode.

Do not operate the buttons on the remote control.

It turns out that cleaning does not help, the gum spends its electrically conductive power over time, and the graphite deposits on the patch of the gum squeegee are erased. How can you get a remote control with such buttons? For a help kit for repairing remote controls. The warehouse contains a small tube of silicone glue and gum contacts, which should be carried out in front of the eyes.

The old patch is carefully cut with a blade and a new one from the set is glued in its place. The number of units required for repairs is 3-5 remote controls.

Another option is to make the remote control work by using electrically conductive glue “kontaktol”, which is applied to the defatted patches of gum kilim. However, these methods of updating remote controls cost pennies and can be difficult if you need to repair a lot of remote controls or the remote control cannot be found for sale. Microcircuits in remote controls rarely go out of tune. The Raju would like to deprive him of respect for the malfunction of a mechanical nature

• cutting off the paths,
• filthy soldering,
• stopping at the crossbars between the wooden path and the graphite conductors, which are so present, the stench is caused to the beasts of the first. It will remain accessible and may appear for an hour. Please note that the batteries in the remote control are quickly draining.
