screen black, but phone still on

Hi,

My phone screen has been acting up for a while now, causing the screen to go black, seems to be only when i start the phone up into the OS.

By that, i mean whenever i boot into recovery, the screen works perfectly and has no issues, but when i restart the phone into the the OS, the screen goes black after the "OnePlus" logo and stays blank. sometimes it comes on for a split second.

ive tried installing another OS, with no prevail. Could it be the kernel? i have no idea.

HELP!!!
