Samsung TV Turns Off And Turns On Spontaneously

The life of most people without a TV is simply unthinkable. Therefore, if any problems arise with him, the person immediately tries to solve them. One of the most common problems is the situation when the TV spontaneously turns on or off. Naturally, to eliminate this problem, you must first find out the cause of its occurrence.

Incidents

There are a number of reasons why the TV itself can turn on or off. But they cannot be called breakdowns. Such situations include incorrect device setup. There are many different models that, in the absence of impact directly on the TV or on the remote control, can automatically turn off. Also, there may be a randomly set program, according to which the TV turns on at a certain time. Therefore, if the TV itself turns off or turns on, you must immediately check these functions.

Often when these problems occur, the reasons are not on the TV at all. Cases are common when the reason lies in the unreliability of the outlet or in problems with the network (power surges, etc.). Poor wiring contact can cause malfunctions. This problem can be calculated using a special indicator that will help measure the voltage in the outlet.

Serious problems

I highlight the following really serious problems that lead to turning the TV off (off):

  • dust accumulation;
  • problems with the power circuit;
  • power surges.

The simplest reason why the TV itself turns on or off is the incandescent dust on the board. Dust can not be called a strong electrical conductor, but sometimes this parameter is enough to provoke a short circuit of the contact pads on the printed circuit board. An excellent solution to this problem is to use a conventional vacuum cleaner, which must be walked around the device with the rear panel of the case removed.

The next reason for spontaneous shutdown of equipment may be problems with the power supply circuit of the inverter. The cause of such problems is the formation of small cracks on the board, resulting from frequent voltage drops, heat, or exposure to high humidity over a long period of operation. Also, power circuits can fail due to breakdown of capacitors or places of connection of terminals of elements with pads of a printed circuit board.

The malfunction described above is a big problem, the elimination of which will require the involvement of a professional and the use of a specialized tool. You can detect the presence of this problem yourself. First, turn off the power by removing the back cover. Next, you can proceed to the visual inspection of the board using a special magnifying glass. Also, you need to take care of the good lighting in the room. The inspection procedure must be done as carefully as possible, since even the smallest cracks can cause the TV to turn on and off periodically independently.

The real misfortune of almost all modern electrification networks is constant power surges. This phenomenon very often leads to breakdowns of household appliances and its unstable operation when the appliance turns on (off) on its own. Voltage drops in the network lead to the burning of certain diodes, capacitors and other very important devices. After heating these parts, they begin to issue a breakdown, which is a signal for the fuse responsible for powering the device.

If the implementation of the above recommendations has not yielded results, and the TV still turns off itself, then to establish and subsequently eliminate the breakdown, you need to attract a professional from a special repair company. Simple shabashnikov cannot be involved in such tasks.
