Why does the TV turn on and off?

Our daily life is hard to imagine without a household item like a television. 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 player of music and video, a screen for a game console, and of course for watching cable or satellite television. However, like all home appliances, a TV can fail. Breakdowns are of a different nature, simple and complex. Those that you can repair yourself and those that can not be fixed without the help of a wizard. One of these breakdowns is the problem when the TV spontaneously turns on and off. The reason why the TV itself turns on and off we describe in this article.

What you need to know

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

Non-mechanical failures and their repair

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 function to turn off the power supply if the system detects a problem with the signal or if the commands from the control panel do not correspond;
• was randomly installed a program - a regulating timer, which is responsible for turning off the power and entering the TV in sleep mode.

Fixing these problems is easy enough; to do this, you need:

• use the remote control or control panel on the TV case to enter the function menu and check the settings; if you find inconsistencies, customize it;
• in the second case, simply disable the timer program or customize it for yourself.

Also, do not forget that all modern TVs have protection against voltage drops in the power grid. That is, you need 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 spontaneous turning on or off of your TV is improper operation of the power supply. It is quite simple to check its operation: if the indicator on the TV case is on or blinking, but the device itself does not respond to the turn-on signal, then the problem lies precisely in the power supply. It’s impossible to repair it yourself, so the TV needs to be sent for maintenance diagnostics. If the indicator is still lit, and 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 from the antenna or to verify the integrity of the antenna itself. If, when turned on, the indicator does not light up and the TV shows no signs of life, then in this case we can safely talk about a power supply failure.

There are cases when the TV turns itself off and immediately turns on, at what happens quite often and in a short period of time. If we 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 activating one channel, the shutdown may not occur, but when switching to another channel, the technician works for a couple of minutes and turns off. Let us single out such reasons why the TV is turned off in this case:

• has dust on the board's microchip, which does not give a signal to get to its destination by blocking tracks;
• as mentioned above, there may be voltage drops;
• possibly faulty supply circuit of the inventory;
• software crashed.

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

Inventor can also fail due to the large amount of dust on the board. The presence of microcracks leads to the failure of this part of your TV.But there are a couple of reasons for which the Inventor breaks down:

• voltage surges;
• equipment overheating;
• high humidity indoors;
• bloating capacitors of the motherboard.

The last reason is especially dangerous, since in order to fix it it is necessary to make a complete replacement of the capacitors, or the board itself, which is not cheap in itself.

Conclusion of

So, in order to find out the cause of the breakdown yourself, it is worthwhile to disassemble the TV and carefully examine all the details mentioned above. However, this requires some knowledge and experience. Therefore, we recommend that you contact the service or the master.

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