The TV stops responding to the remote control

What to do if the TV does not respond to the infrared remote control?

To find out why the TV does not respond to the remote control, follow these steps:

Press the button/joystick on the back of the TV to see if the TV responds. Does the TV respond to the button(s) on the TV itself?

Yes. Go to step 2 to check the functionality of the remote control.

No. Go to step 3 to see if the TV can be restored to its original functionality.

Batteries have run out of life

It is the batteries that you need to check first. There are clear indicators that they are exhausted or close to it:

Even new batteries can fail quickly. Now there are many variants on the market, the quality of which is beyond any criticism. You should buy from famous producers. Such batteries should last for years.

How to check the batteries in your TV remote control if it does not work

Repairing the buttons

You have two choices, either you can buy the same buttons and solder them on the board, it is desirable to replace them all, because it is not always possible to find out which of them behave hooliganically because of the instability of this failure.

Or disassemble buttons and put them in order. it is not always possible and depends on the button type. But in my case it was possible and not difficult. If you have such buttons as on the photo below you can easily cope.

It is not difficult to disassemble this button, you just need to pick up the metal part with a sharp tool and “unbuckle” it from the plastic part, making sure that the button insides did not fall out or get lost. The disassembled button looks like this.

But to restore them it is not even necessary to unsolder them from the board. See below.

Take everything apart and clean. For this we use cotton swabs and alcohol. You can use an eraser. You can use a carburetor cleaner or WD40, but you don’t have to spray it on the board. Below you can see that some of the pins are cleaned and some are not yet. Copper heels can also be rubbed with honey with the fingers of your hand. Since you’ve gotten this far

Everything is cleaned up. Pack it up! Pay attention to the correct installation of the copper heels. dome upwards. Serviceable and not worn heels should spring when you press them. After you have snapped the metal staples by hand, it is necessary to put them in their place by pressing them by the edge of the tool.

Most of the time these steps are enough and we can put everything back together.

For the savvy

For those who are more familiar with the repair of radio equipment and has some knowledge and skills. Information on.

In my case, the buttons were divided into two groups KEY 1 and KEY2, each with its own wire with a voltage of 3.3 volts. There are three wires on the button wire terminal, one is ground and two are for buttons. When the glitch started, the voltage in one of the wires dropped to 1.8 volts and that’s without pressing any buttons. I did not immediately believe that the leakage is caused by the buttons. Since there are ceramic capacitors in the circuit, the suspicion at first fell on them, this happens with them keep in mind.

But a careful check showed that in this case the cause is a leaky button. The button can behave quite normally, short out when you press it and do not test it with a tester if you do not press it. But as soon as it has been under voltage for a while, there is a current flow to the ground. You can tell by the voltage drop in one of the circuits when 3.3 volts goes down, starts the TV glitches. Sometimes it would stop responding to the remote control completely until the button board was disconnected from the circuit.

Well, I hope this information will be useful to those who have faced similar problems.

TV receiver malfunctions

If checking the remote control confirmed its functionality, then the cause of the breakdown is probably the TV itself. Usually no reaction on the remote control.
