3. Mainboard Issue

Sometimes, your television can go completely black screen, no access to the television menu, and the tv turns off when connected to pc running Windows 10. The television screen is black as long as it is connected through HDMI to the PC. 

If you unplug the HDMI from either the PC or the television, the television appears back on and you can access the menu.

This problem happens for a broken joint or loose solder on the HDMI ports. It causes a fault when the device’s microprocessor does a check on startup.

Sometimes, when connecting your PC to your 4K television via HDMI, you can face black screen flickering symptoms each time you turn the television on.

The flickering means the screen goes black for a second or two and then comes again. Each time you turn the television on it will search for an input signal. 

There is a setting called overscan in your television that causes it. The overscan setting expands the picture to fit a 16:9 aspect ratio.

It is meddling with Nvidia’s scaling characteristic which causes a strange loop where the screen continuously flashes off and on. 

Also, you can sometimes see your TV going black when connecting with a PC through HDMI input, even with the latest driver. It happens for the Nvidia control panel issue.

In the case of the overscan setting problem, firstly, disable the overscan setting. Now, switch your television off and on. Finally, you will see the black flickering is gone.
