Hello @Mike20066 

Sorry to hear that you are having problems ... I would like to help you.

In the simplest case the internal display cable behind the screen is no longer seated correctly. It has come loose slightly or screen backlight is defective.

Recommendation and solution

In your case: Service is required !
- The computer should be disassembled and checked.
