iPhone x does turn on but screen is totally black
I have an iphone x that previously worked like a charm. I replaced the screen to an oem oled screen 3 months ago. Yesterday the screen would go black if I lightly pressed the upper right corner. Today the screen is completely black and does not respond to touch. The phone turns on and everything works, except the screen. I even restarted the phone and restored it via itunes but that didn’t fix the problem.
Worth mentioning that I changed the housing a few days ago after which the phone worked like a charm until it suddenly didn’t.
What could be the issue here?
