TV remote does not work

TV is present in every home today. Thanks to the development of technology, today's models of TV receivers are equipped with a remote control (RC). It is this small item that greatly simplifies the use of the TV. However, often the remote control fails: the channels stop switching or some buttons do not fulfill their functions. Of course, there is no problem in acquiring a new remote control, but at the same time, you can figure out the cause of the breakdown and fix the useful accessory yourself.

Why the TV remote does not work

To understand why the TV stopped responding to the remote control, it is important to find out what is wrong - the remote control or the TV itself. To do this, you need to use a separate remote control and buttons located on the TV itself. If there is no reaction to the remote, then the reason is in it. At the same time, if during control via buttons on the blue screen errors occur in the execution of commands, you need to contact a specialist who can determine the malfunction of the TV itself.

ATTENTION! If the remote control malfunctions, you should find out: the device does not function completely or some buttons still work.

TV does not respond to the remote

If the TV receiver does not react to the remote control completely, 3 reasons are possible:

• battery failure - the most common and easily eliminated cause;
• LED malfunction;
• communication defect on the soldering circuit - this part is located inside the remote control and to fix this problem it is necessary to fix the internal board.

To begin with, it is recommended to replace the batteries. If this does not help, then you should inspect the LED. It is located at the top of the device. His job is to transmit an infrared signal to the TV. To check the LED, you should use one of the modern gadgets, for example, a mobile phone with a camera. It is necessary to point the camera at the remote control and press any button on the remote control. If the LED works properly, a strip will appear on the mobile screen; in the reverse situation, the LED may be damaged if the remote control falls.

After eliminating the first two options, you should look for another cause of the malfunction. It is recommended to disassemble the remote control and carefully consider the details. The cause of a broken remote control may be a frequent fall of the remote control, as a result of which the board could crack, or internal parts of the remote control could break. The result is a violation of the contact details of the remote control.

IMPORTANT! To consider the elements of the board, it is recommended to use a magnifying glass (magnifying glass).

Only some buttons work

In the process of checking the remote control, it may turn out that only some buttons are functioning. There can be several explanations for this:

• spraying between the most used buttons and the board is often erased;
• heavy contamination of the console;
• liquid has spilled onto the accessory;
• increased humidity in the room - because of this, condensation forms on the device, which gets inside.

With any of the above options, failure is not considered an excuse to purchase a new remote control. It is quite possible to fix it yourself.

How to repair the remote yourself

Remote control repair depends on the cause of the malfunction. First you need to replace the batteries. If the cause of the device failure is a malfunction of the LED, it should be replaced. You can purchase a new item on any radio market.

In the event of an internal failure of the remote control, it should be carefully disassembled so as not to damage the internal elements and the board.

ATTENTION! If you identify internal problems with the operation of the remote control that cannot be fixed on your own, it is recommended to contact the workshop.

Inspection of the board should be done with a magnifying device. It is better to start this procedure from the places of access to power (batteries). Further, if damage is detected in the electrical circuit, the damaged part should be replaced. If microcircuit damage is detected, it is better to replace the remote control with a new one.

On the bottom of the remote control, when it opens, there may be an oily liquid. You can remove it by wiping the surface with alcohol.

IMPORTANT! After cleaning, all elements of the remote control must be well dried.

If the coating is erased between the buttons and the board, it can be restored (purchase a set of remotes on the radio market or come up with foil linings).

Heavily contaminated remote control, of course, can be brought back to life. To do this, it must be cleaned using an alcohol solution.
