The display does not light up but itunes detects the ipad. I disconnected the battery and it seemed to work, but after some use it is no longer accessible (itunes, however, detects it). Some advice? Thank you
Sounds like maybe the LCD flex cable is coming loose. I’ve actually seen a guy smack the opposite side of an iPad 2 and correct a loose cable. Not sure if the 4 flex would react the same. It is a different connector altogether. You may try putting it on its right side vertically, then bump it down into your palm or lightly onto something kind of soft like rubber. Then soft reset. Hopefully your LCD isn’t going out and this helps. Otherwise you gotta open it up to investigate.
