[Q] [SCREEN PERMANENT DAMAGE AFTER 5 REBOOTS][Looking for a fix) topic

Hi XDA, i´m new in the forum, and i just want something of help, i have my G2 D800 for 6 months, always Stock, until i got bored and installed VANIR AOSP Rom, i was watchin' some videos and the Galery app started to Fail, the only solution was reboot, failed and failed again so i reboot 5 times, then the cellphone frezzed with a screen like the TWRP recovery back but without the letters (im givin just an example) then rebooted with some lines on the right side of the screen and never dissapeared ( i left the phone 30 min OFF thinking that was a warming problem), now the problem is that i live in Bolivia, so i'm not Able to get a Warranty Repair, the only thing i can do is identify the problem (with yours help) buy the parts on Ebay/Amazon and repair with a unautorized repair guy here......

Waiting for a soon answer, Grettings to all!
