Screen back light works, device will reboot and sound comes out but there is no image displayed.
Is it possible that a connector came loose? Or more likely hardware failure?
What happened to the iPad prior to this issue; was it dropped, damaged, repaired or came into contact with water? If the iPad was dropped or damaged, then you probably have an LCD issue. If the iPad came into contact with water, then it’s probably a logic board issue. Of course, it could be either one of those regardless of the triggering issue. At some point, this device will have to be opened and the LCD tested to help figure out the issue.
