Screen suddenly went black mid use?

So all I was doing at the moment was watching youtube when the screen just went black. It was still powered on, but the keyboard and the screen were dark. I can turn it off and on and it’ll do the startup sound.

I’ve already tried booting it in safe mode, NVRAM/PRAM mode, and recovery mode. I think it’s probably a hardware issue but I just don’t know enough to know.

Any help is appreciated.
