How to determine the malfunction in a Samsung TV
Pay attention to the following points in the operation of the TV. Let’s start with the simplest non-technical things.
As recommended by Samsung, unplug the TV, wait at least a minute, or better 2-3 minutes. Turn on the TV, sometimes, but very rarely, the TV will start working normally.
Disconnect all HDMI cables and check how the TV works. If this is difficult, turn off Anynet+ in the TV menu. This is a standard for interaction and control between different devices over HDMI. One of the features is to control all devices at the same time. For example, if you turn on a game console, the TV turns on automatically by receiving a command from the game console. Sometimes one of the devices is in standby mode, reacts to the inclusion of the TV and gives the command to turn off.

This can be the reason for turning on and off the TV, poor interaction between devices of different manufacturers or devices made with a big difference in time.

When the TV turns off the screen becomes black, after a while the image appears. The TV makes a restart, the logo appears as when you first turn on.
If the image disappears and then appears without restarting the operating system. This is an electronics malfunction. You should look at the secondary signs, if the image is gone but there is a sound, in 90% of cases the screen matrix is faulty.
If the image is lost along with the sound, the main board is faulty.
If the TV reboots (the logo appears every time), this means the TV cannot get into working mode. In most cases this means the power supply is broken, or other electronic components, main board, WiFi module, screen matrix are broken. One possible problem, the power supply is not working normally. At a certain moment the TV goes into emergency mode, the TV turns off and then on again.
