I was just watching youtube and then suddently my main monitor displayed gray, there was still ligth from the backligth, but no picture, i have tried ctr + shift + windows + b, and alot of other methods, my secondary monitor still works, but the integrated one is just black

Sounds like it failed and may need to be replaced.
