Screen black and when pluged in phone won't stop viberating
I recently changed the screen on my 5S when I plugged it in the screen stayed black and the phone would vibrate every 5 seconds and wouldn't stop. It shows up in iTunes. Can any one tell me what is broken? I don't think it's the digitizer because we tried to switch it back to the old screen and the same issue occurred. We also put it into DFU mode and did a factory reset.
