Screen will not function no matter what
Hello, I have an iP;hone 4s that suddenly had the screen black out while being used, the vibrate still functions so I know the device still powers on. I have tried everything I have found so far, disconnect the battery for a harder reset, doing a Power + Home reset, and reconnecting the screen connectors. Nothing has worked. I even put a different screen on the phone and that did not work either. The connectors appear to be fine, no damage. Does anyone have any idea what might be wrong?
