Exclamation Black Screen, Phone On, But No Backlight

Ok so before I begin, I've read everything online and cannot figure this out. I've searched the forums for hours and still no luck.

I have the HTC One M7 with T-Mobile

I've had it since December with no issues at all, and still in mint condition. Never dropped.

I have it rooted, with boot unlocked

ViperOne ROM Installed, stock kernel.


Ok so Tuesday night I was going to bed (phone still on and working) and plugged my phone in to the charger to charge for the night as I usually do every night. Wake up in the morning and hit the power button to unlock the phone and to my surprise the display doesn't come on. As I said I've never dropped this phone in the entire 9 months I've had it, nor has it ever gotten wet.

This is NOT the first time this has happened either. I've had the phone display flicker on/off and after a couple times it will just stay on. It's also went off and I've fixed it by holding a light to the sensor in the top left and it came on. This time I'm not having any luck.

Please help! It's rooted, with custom ROM, and boot unlocked, therefore I cannot send it in for repair as warranty is voided. I've tried restoring it back to stock the best I can via mirror Android to PC program, but it's very difficult. I've restored it once before, I just don't get why it's not working again with me holding the light to the sensor. Any help and/or suggestions would be greatly aprreciated!! Thank you!
