PS3 display is not working

I'VE ALREADY TRIED THE HOLD DOWN that "resets" the display but doesn't work

I've tried different hdmis, and different ports the controler isn't turning on all the way and there's no yellow light. Along with it is no audio. All the answers I see are the hold down the power and reset but that is not working for me. My TV is fine it displays no signal and I've tried it onto different monitors it was working fine yesterday.

Any help
