HELP! LG G2 Screen Won't Come on But Touchscreen responds topic

I've had a long journey with this phone. Only got it a week ago. I downgraded the phone to the LS980 ZVC firmware using LG Flash tools, rooted with ioroot 25 and flashed TWRP with Autorec. Then installed the Cloudy G2 2.2 Rom. USed it for a while, but then wanted a taste of lollipop. So I downloaded the latest CM12 nightly. Upgraded TWRP to 2.8.4.0 using Blasgator's bumped zip, did full wipe, flashed the CM12 Rom, flashed the ZV8 Radio and then flashed gapps. Booted into CM12 fine and used it for a while. Then, the phone randomly shut off, and wouldn't power back on and I panicked. Power button gave no feedback or sound. I decided to try download mode and plugged the phone into my PC, it was detected and flashed back to to stock firmware, still nothing on screen. The phone boots and I can here sounds, I can also hear touch tones when I touch the screen, but I have nothing on my display. Please help. It would be tragic to lose my phone after less than a week :(
