If the equipment turns off almost immediately after switching on, then the matter may be in the button.

The indicator turns green and then turns red again
Such color switching indicates that the CPU generated a signal to turn on the device, and it was sent to all modules for its execution. If any module is out of order, it cannot execute the command. For example, a failure in the power supply does not allow it to go into the desired mode. In this case, the processor, not receiving confirmation from the power supply unit about normal operation, gives a signal to cancel the inclusion of the TV receiver and returns it to sleep mode.

It should be remembered that it is not recommended to leave the television receiver in this mode for a long period of time, since when the unit appears to be disconnected, all the power supply circuits remain energized. If a voltage surge occurs in the power supply network, then all primary circuits will burn out, after which the TV receiver will refuse to turn on. Therefore, the unit should be turned off with a button located on its panel in order to reduce the risk of burnout of the electronics.
Particular attention should be paid to the screen: even microcracks barely discernible by the eye can affect the quality of the picture. This can also include broken pixels. To diagnose the latter, special tests are provided in the firmware that reveal dark or light points on the screen.
The dead pixel test looks like solid pictures of different colors
Indicator blinks randomly
This behavior of the indicator indicates that a failure has occurred in the TV set, and it does not carry any more useful information. Full diagnostics of the electronics will be required, starting with the “ringing” of the power supply and ending with the converters on the system board.
Inadvertently, some specific TV functions could be activated. For example, child protection, which blocks the inclusion of equipment without a remote control. It is worth carefully examining the settings for the running functionality of such a plan. An extreme case. factory reset.

When the help of the master is not required
Very often, the owners of TV sets panic and start calling the master at the slightest problem with their device. But if you calm down and take a sober look at the situation, then there may not be a breakdown in equipment. It is required to check the behavior of the TV receiver for some symptoms.
