Why does the TV turn on and off itself

It's hard to imagine our daily life without such a household item as a TV. Now literally everyone has this unit, and its purpose is also different. It can be used as a monitor for your personal computer, as a music and video player, as a screen for a game console and, naturally, for watching cable or satellite TV. However, like all household appliances, the TV can fail. Breakdowns are of a different nature, simple and complex. Those that you can fix yourself and those that cannot be fixed without the help of a master. One of these breakdowns is the problem when the TV spontaneously turns on and off. We will describe the reason why the TV turns on and off itself in this article.

What you need to know

So, let's start with the fact that in this article we will describe the problem associated with more modern TVs. Old tubular TVs do not fall into this category, as few people now take up repairing such old equipment. Therefore, it is recommended that if you do not have certain knowledge in electrical engineering and microcircuitry, do not proceed with the repair yourself, as this can lead to an aggravation of the problem. Although the cause of the breakdown is not always mechanical, the software can be configured independently.

Non-mechanical breakdowns and their elimination

This type of malfunction can be divided into two categories:

• when the equipment was incorrectly configured and put into operation. Most modern TVs have an automatic disconnections power supply, if the system detects problems with the signal or does not correspond to the commands from the control panel;
• a program was randomly installed - a regulating timer, which is responsible for turning off the power and entering the TV into sleep mode.

It is quite easy to fix these problems, for this you need:

• using the remote control or control panel on the TV case, enter the functional menu and check the settings, if any discrepancies are found, adjust for yourself;
• in the second case, just turn off the timer program or customize it for yourself.

Also, do not forget that all modern TVs have protection against power surges. That is, it is necessary to check your power supply system of household appliances so as not to aggravate the condition and not to burn the electronics.

Other malfunctions and their elimination

The first reason for your TV to turn on or off spontaneously is a malfunctioning power supply. It is quite simple to check its performance: if the indicator on the TV case is on or blinking, but the device itself does not respond to the power-on signal, then the problem lies in the power supply. It is impossible to repair it yourself, so the TV must be sent for diagnostics to a service center.If the indicator is still on, but nothing appears on the screen, try calling the menu on the control panel, which is located on the TV case. When it appears, it is worth checking the network cable coming from the antenna or making sure that the antenna itself is intact. If, when you turn on the network, the indicator does not light up and the TV does not show any signs of life, then in this case we can safely talk about a malfunction of the power supply.

There are times when the TV turns itself off and immediately turns on, and this happens quite often and in a short period of time. If you briefly explain why this happens, then we can say the following: the operation of the TV depends on the frequency at which the signal was received. Sometimes when one channel is activated, the shutdown may not happen, but when switching to another channel, the technique works for a couple of minutes and turns off. Let's highlight the following reasons why the TV turns off in this case:

• there is dust on the board microcircuit, which prevents the signal from reaching its destination, blocking the tracks;
• as mentioned above, there may be voltage drops;
• the power supply circuit of the inverter may be faulty;
• the software crashed.

The first case is the most common, when dust is on the motherboard, it can serve as a microcircuit. Therefore, in order to avoid equipment malfunctions, it is necessary to wipe and blow the household appliance as often as possible.

The inventory can also fail due to a large amount of dust on the board. Microcracks will damage this part of your TV. But there are a couple more reasons why the inventor breaks down:

• power surges;
• overheating of equipment;
• high humidity in the room;
• swelling of the motherboard capacitors.

The last reason is especially dangerous, since in order to fix it, it is necessary to completely replace the capacitors, or the board itself, which in itself is not cheap.

Output

So, in order to independently find out the cause of the breakdown, it is worth disassembling the TV and carefully inspecting all the above details. However, this requires certain knowledge and experience. Therefore, we recommend contacting a service technician or a master.

We hope this article helped you figure out the reason why the TV turns on and off itself.
