iPhone XR black screen
Hey guys so my old iPhone XR is slightly bent and the screen is black. It turns on and makes the charging noise the screen is responsive and the phone vibrates when you swipe up for you to enter a passcode after a reset. I bought a new screen and hooked it up and I turned it on it made the charging noise and when I swiped up it did the vibrate so the new screen works but is still black, I did the hard reset and still nothing does anyone know what is wrong with my old phone?
