A number of buttons on the remote control do not work. Why bother with a faulty remote control? For those who use a soldering iron

As a result of the troublesome operation of the TV remote control, there arises the problem of unclear operation of the power button and other keys.

The first thing that comes to mind in this situation is that the time has come to replace the batteries.

However, after installing new life elements, the problem persists: to turn off the TV, you have to forcefully press the button into the middle of the remote control body, and then the problem will no longer persist.

Why are you excited?

If one or a few buttons work poorly, they are often abused, the reasons could be a few:

  • Skupchennya between buttons and contacts, fat and brood;
  • Wear a flame-resistant graphite ball on the inner surface of the button;
  • Mechanical damage to contact tracks and microcircuits.

How can you verify that the TV remote control is transmitting a signal?

It’s even easier to get started. While the human eye cannot detect the IR signal, it is necessary to use the camera of a smartphone (or someone else).

  1. To do this, simply turn on the camera, point at the IR transmitter of the remote control and press whatever button you want to check.
  2. If you press the button on the remote control, the infrared LED does not shine, which means the button does not work.

However, it’s not a good idea to rush to the store for a new remote control (it costs on average more than 500 rubles), but you can get more of it for a small fee.

How to fix the problem?

Yakshcho the buttons on the TV do not work Or do it every other time, first of all, so that the next step is done - by removing the remote control and cleaning the saw and saw blade.

The fragments of the remote control for different types of generators do not affect the basic principles of the design; to “open” it is enough to use a small cross twist and a thin flat twist (or something lower).

Start by listening for fastening elements - the stink will cause concern for the batteries. Some models of TV remotes have their housing mounted on clips (clasps). In this case, simply pinch the upper part of the body with a knife or a flat twist and pull it out from the lower part.


Having picked up the remote control, follow the next steps:

  1. remove the hum buttons;
  2. Vidality drank all that brood;
  3. Wipe the surface of the contacts with degreaser (sold in local stores) and alcohol;
  4. Wipe the board;
  5. Wipe the coated surface dry with a serving cloth or a cotton swab.

After this, you can pick up the remote control and check the operation of the buttons. Since all the manipulations did not produce results, and the operation of the buttons was repeated too often, it means that the problem lies elsewhere - the surface ball of the buttons' rubber-conducting gum was worn out.

As a result of intensive use, this ball loses its flow-conducting power, through which the contact capacity decreases.

This problem can also be solved with your own hands. About this.

If some buttons on the TV remote control do not respond - repair inspection

Yakshcho the button does not turn on the TV, and cleaning/rinsing did not give any results, the easiest way to update the contacts is to remove a thin ball of gum-conducting gum.

To do this, it is enough to clean the surface of the button with a fine sander. It is necessary to work very carefully, to get literally three to five light rukhs.

Since the contacts of the buttons have graphite filings and have worn off over time, the functionality of the device can also be restored.

Why carry out a simple repair of the TV remote control buttons:

  1. The surface of the contact is cleaned with sandpaper and lightly greased;
  2. From foil on a paper base, overlays of the appropriate size are stamped;
  3. Using super glue, glue the paper side down onto the surface of the button contact.

Often the remote control stops working after being dropped on a hard surface. In this case, the problem may be caused by damage to the microcircuits and contact tracks.

VIDEO INSTRUCTION

In the opinion of the fakhivts, there is no desire to start looking for a new board, since it will be easier and cheaper to get a ready-made remote control from the collection.

Almost all everyday everyday equipment is connected to remote control panels, so if this small device breaks down, people will feel a great deal of discomfort. We know how easy it is to repair a TV remote control at home with your own hands without calling a service technician. Most people just go to the store and even if there is a minor breakdown, you can fix everything yourself.

Statistics on remote control repairs in service centers confirm that breakdowns of either of the most common devices look like this:

  • breakdown of important control elements and subsequent damage to the housing fall from different heights and other mechanical injections;
  • Inodes Some buttons do not work remote controls that can configure their functions easily;
  • the buttons do not function, which are often used, but only work under very strong pressure;
  • The TV's DC operates only from a very close location.

Finding out the cause is not easy, but you need to know the procedure for future repairs in order to avoid a breakdown that occurred, otherwise it is cheaper to buy a new remote control rather than reanimate the old one.

Important! If the remote control buttons do not work for your TV, first proceed to the repair, try inserting new life elements - in 80% of cases the remote control requests the wrong mode . These simple steps will help you revive your Smart TV remote control.

We are carrying out repairs

Which section is recognizable in detail, and please place the TV remote control in each specific area.

The result is a fall

If homeowners often throw away the remote control for the TV, then there will be serious damage to the device, the repair of which will be difficult - without a soldering iron, you will not be able to re-solder anything that has sprung up. To reconnect, there is a faulty board, and you need to re-solder – є original verification method, It is necessary to reconnect while the batteries are in the operating station. This method can be used to check any remote control regardless of the brand - Samsung, Philips or LG, since the principle of operation is identical for all.

Whether you have a digital camera or a mobile phone, this includes Infrared viprominyuvach, we check the TV remote control for further help:

  • turn on the camera on your mobile phone;
  • We point the remote control at the camera window, which brings the mobile phone closer to the button on the remote control;
  • If the remote control sees a signal, then a large red dot will appear on the screen of the device.

This clearly shows that the board is working and there is no need to check all the buttons. As a matter of fact, 100% of the time, the control board needs to locate and visually identify the cause of the breakdown.

We can see the elements of life by carefully and without forcefully disconnecting the halves of the remote control from the TV, having first unscrewed the fastening screws. Once the clamps are installed, then use a thin twist, but without fanatical force, so as not to damage the delicate structure.

Please! To carefully look at the board, press your paw, without having to succumb to the keenness of your eyes - any defects will be difficult to recognize.

Repairing the remote control in this case can only be done by only people who have sufficient knowledge and skills of working with a soldering iron - it would be better for the average person not to get into such a lower device. As a result of frequent falls, the LED mount may become loose, the battery terminal may fail, or the quartz resonator may go out of tune. The first two breakdowns can be identified visually. To determine the correctness of the resonator of a small box with contacts soldered to it, you need to carefully shake the entire device, if you feel it’s crazy, then you need to change it.

Sticky buttons

Please ask: how to repair the TV remote control if some buttons stop working. After an hour of use, the center of the TV remote control could waste the vologist through the displaced moisture from the place or the water that was suddenly spilled. As they say, in the middle of the process the oil condensate drank, which became stingy, joining with water vapor, which greatly complicates the operation of the buttons when pressed. This type of repair of remote control buttons can be done on your own: you don’t need any special skills, you just need some care and patience to clean the TV cleaning device.

  1. Carefully understand the remote control.
  2. We wipe the board with a cotton swab, soaked in alcohol- this simple method can be used to remove deposits from contactors that may cause contacts to become stuck. Zusilla apply not varto – virib dosit nizhny.
  3. The same method is used to wipe the contact rubber pads of the buttons.
  4. We clean the spring contacts of the life elements, if there are traces of oxidation, their visible debris emery paper.
  5. After cleaning, we give an hour to dry all the elements and remove the devices.

Note to Koristuvachs! Chinese factory remotes stop working after cleaning with alcohol! Chinese folded Samsung models are especially popular.

To cleanse the inner spores, such lower sprouts must be vicorized cute ta water- for additional care, all the fillings are carefully wiped, then they need to be washed with plain water at room temperature, rubbed with paper servettes, and left to dry. After the residual drying, carry out the folding of the structure and check the feasibility.

Resuscitation of buttons

Repair of remote controls, if the buttons are often damaged, their lower contact surface has been worn off, should be carried out at home. Why do you need these materials:

  • foil, which has a paper base on the fold - this is not necessary for clear gluing; similar packaging from a cigarette pack is better suited for this;
  • garnium glue type "Moment"» Or with a fluorescent base on silicone.

Some retailers have special glue for such needs, but they cost more for the remote control itself, which in our situation is unprofitable for repairs.

The repair method is simple.

  1. We disassemble the remote control and extract the humic part.
  2. On the bottom surface of the buttons, without needing to do so, we glue circles or squares of foil.

You can find it in stores special sets, there are buttons with gun-resistant filings and metallic glue for their fastening. Such a kit can be useful for repairs to update your remote control.

If the remote control for the TV is broken because someone stepped on it, then repairing it will cost you much more than getting a new one. At the market, you need to select an exact copy of your remote control, if you don’t need any adjustments, insert the batteries and tinker with it. Until the purchase is completed, you can get by with manual controls: it’s easy to finish, and the axle is more foldable.

The experts say that any repair of any TV remote control can be done without any need of repair: replacing the components or gluing new spare parts from the repair kit is possible and without much knowledge. In case of any breakdowns, you should contact the service department, since repairs will be more expensive than the remote control itself, then it’s easier to get a new one.

Home masters are encouraged to watch this video, which shows the exact indications for repairing the MPC:

Today's TVs, regardless of brand, model, size or design, are controlled using a remote control. Often there are problems that do not allow clicking channels, entering/vimikating TV receivers. To clarify them, it is first necessary to identify what the TV remote control does not do.

The main reasons for the malfunction of the remote control

There are a number of reasons for the prevalence of vomiting. Here you can store the following:

  • Battery life has expired. As soon as the robot remote control was damaged, the device completely stopped responding to the pressure of the buttons, the reason lies in the vitality of the day.
  • Output from the infrared sensor on the TV. In other cases, this can be achieved through a switch between the red light on the equipment panel and the remote control.
  • Failure of infrared signal transmission. To check whether there is a malfunction, you can test your camera or mobile phone. If I look through the lens for an hour and press the buttons for an hour, the LED flashes, the cause of the breakdown is different.
  • Problems with the robot PZ. Today's TVs often have problems with software. They can be eliminated by restarting the equipment. If this does not help, please update the software to the latest version.
  • The damage from the side of the forces. If at the time of checking on other TVs it was discovered that the remote control is working, it is necessary to adjust the rest.
  • Wearing the gum-conducting gum. This failure is characterized by the functioning of certain buttons and the presence of noise when pressed on others.

Chi Varto repair remote control?

Remote control - dosit tenditna rich. Fall, inaccurate conduct, penetrating vologi, brood and saw - factors that flow into the fruitfulness of pristosuvannya. The control element, which is in good condition, is impossible to repair in most cases or is invisible from an economical point of view. The repair rate is high, and the service life, after disassembly, is minimal. The most urgent is the purchase of a new device. You can choose either an individual model, created specifically for TVs of the same brand and model, or a universal one. The rest may need to be set up in advance to communicate with the previous TV.

Often the reason for the lack of response from the TV receiver when pressing the keys on the remote control is the accumulation of saws and tools. This problem occurs in devices that are installed in the kitchen. The problem can be corrected by disassembling the remote control and carefully cleaning any foreign parts from accumulated parts. For this purpose, use a cotton stick, soaked in alcohol and a tinker.

Singingly, many readers have been concerned about repairing the TV remote control.

Dosit often on the remote control or frequently press the buttons. This malfunction can be caused by a variety of reasons: bad batteries, clogged contacts or breakdown of other elements.

In case of any problem, it is better not to rush to disable it, but to try to repair it yourself. Moreover, you can often find a clear remote control of the original model, for example, a Samsung smart TV, on sale.

Classmates

See the breakdowns

It is often necessary to repair the remote control depending on the type of breakdown, or more precisely, the level of severity of the malfunction. Even if there was no problem, anyone could end up with a lot of problems.

If you know the types of damage, they can be easily removed with clammy hands.

Most often there are a number of types of breakdowns of the remote control:

  • parts of the fall that could lead to the out of harmony of quartz and important elements; There may be a daily reaction to the song keys, and when pressing on others, there is no such thing to be afraid of; There is a lot of work at the buttons that are often pressed; Sometimes, in order for the buttons to work, you have to press hard on them; The remote control is working, but only close.

Varto means: Not always the lack of reaction when pressing the buttons may result in the device going wrong. It is possible that the batteries are simply dead, which can be easily replaced.

If the reasons are identified, then half the problem is solved; you need to know the repair procedure. Please take a look at the report on the troubleshooting procedure. It is difficult for repairs to occur due to the type of breakdown.

Breakdowns after a fall

Parts of the equipment may cause serious damage or repair of any other equipment. This means that the connection in the solder joints on the circuit is often broken.

Since the batteries are all right, the remote control can be checked with an additional camera or phone. The fragments are installed in the new infrared viprominyuvach, the building will reveal any guidance.

This procedure may follow the following scheme:

  1. First of all, we turn on the camera on our smartphone.
  2. We force the remote control onto the camera. We bring the camera close and press the remote control button.
  3. When you press a signal on the remote control, a red dot may appear on the phone screen.

There may be another signal. For this type of device, you need to remove and remove the board. Further, this fee will need to be carefully examined and necessary repairs carried out.

It is necessary to select the accessories with special care - it is important not to damage the body of the device. Before you do, you need to remove the batteries and clean the area around the bookmark. As there are screws, the stink gets twisted.

If the device has a clamp installed, it can be opened with a screw or a thin screw or a plastic card. To do this, you need to insert a screw or a card into the hole, moving it between the upper and lower parts.

Restore respect: In order to be able to take a closer look at the board, you should be very careful. With this help, you can clearly see the device and avoid any possible malfunction.

Repairs can be done by someone who knows how to use a soldering iron. If frequent failures occur, the LED may fall off, the battery contacts may come out, or the quartz resonator may be damaged.

In the same way, you need to shake the plate and listen. If you are careful not to play around, it can cause damage to the quartz resonator.

Next you need to remove this element (as seen in the small box). Then a new one is changed. You can get it at any radio equipment store, as well as in an online radio parts store.

Vibirkov robot buttons

Sometimes a breakdown can occur due to severe obstruction, damaging the saw in the middle. Don’t forget that problems can occur through spilling tea, water, or other items.

In these situations, the oil condensate is at fault. These types of breakdowns can be resolved independently.

The repair procedure must follow the following scheme:

  1. The remote control becomes understandable. The board is wiped with a cotton swab soaked in alcohol. For the shell of this toll, the sludge is cleaned.
  2. It is also necessary to wipe the contact pads of the keys on the gum part. You can clean the case. You should not rub too hard, otherwise you may damage important contacts.
  3. Okremo Varto clean the spring contact. If the contamination of the element is too strong, to clean the traces, quickly scrub and wipe with a sponge with a harsh base.
  4. After cleaning and drying, all parts must be collected at once.



Take note: There are a lot of complaints about those who, after cleaning the remote control with alcohol, stop working, especially often with Chinese analogues of the Samsung remote control and other models.

Thus, Chinese models may become damaged after much processing. Therefore, in order to remove these inheritances, prepare household goods and water.

Then a sponge is placed there and all the clogged parts are wiped off. After this, all parts are cleaned with great care with cold water, wiped with a paper cleaner and left until completely dry. Finally, the remote control is assembled.

What's so tiring if you don't press the buttons so often?

Sometimes the buttons on old devices wear out due to wear and tear. The buttons themselves are erased, and the conductive filing in the remote control does not react when the button is pressed.

In these situations, you can easily set up a remote control with your own hands. Required items for repair:

  • foil, paper base on one side;
  • silicone-based glue and “Moment” glue. There are also adhesive things behind the base that need to be carried out.

How to fix the problem yourself:

    1. We first disassemble the attachment and extract the humic part.
    2. A foil paper is glued to the back of the buttons. Foil is perfect for cigarettes or chocolates.

  • Also, for gluing, there is a special conductive glue, but its ability to do so is high.
  • We sell kits with glue and buttons with sawing. These kits can be easily used for self-repair of the remote control. In the area where there were old buttons that were damaged, you just need to glue new ones.

    • If the remote control is still damaged and if attempts to repair it with bare hands did not lead to a satisfactory result, you will have to replace it with a new one. Moreover, you can find similar products on sale, so you don’t need to specially adjust them for your TV. Are you experiencing inaccuracies, inaccuracies or incorrect information? Do you know how to earn a statue by stealing?

    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 oscillograph 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 light 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

    Check the condition of the batteries. If the supply voltage is less than 2.5 V, the batteries must be replaced. With a voltage greater than 2.5, check the short circuit circuit with a multimeter. For reference elements, it is necessary to add 1...3 A. Yakshto Ikz
    Then they open the remote control. This operation will require good skills and accuracy. The main precaution here is not to remove any ripples on the body of the PDK and not to loosen the clamps. To open the remote control, use a basic twister with a thin tip (currently on sale are special twisters with a tip 10...20 mm wide and 0.5 mm thick with a short handle).

    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


    the voltage of the microcircuits;
    malfunction of the quartz resonator;
    presence of two or more pairs of closed contacts on the other board;
    breakage of conductors between the microcircuit and the contacts of the other board;
    microcircuit malfunction.

    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

    Possible causes of malfunction:
    the amount of stress in the life of a person;
    malfunction of power supply elements;
    LED malfunction.

    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

    Possible reasons:
    breakdown of one of the power supply transistors;
    presence of two or more pairs of closed contacts on the keyboard;
    microcircuit malfunction.

    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

    Possible causes of malfunction:
    Changed insulation support between the microcircuits and contacts of the other board;
    changing the insulation support between the graphite jumper and the other conductor to pass under it;
    microcircuit malfunction.

    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. The chips are supplied from the board separately. If you follow this command from the MDC, you can proceed 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

    Possible causes of malfunction:
    increased support for short-circuit contacts on the keyboard;
    cracks on the board.

    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.

    M.Kireev

    After a number of accidents, the functioning of remote control panels for televisions 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),


    They are the ones 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 troin. further, 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.
