We have this old iPad 2 which was working fine until recently. When you try to turn it on, the Apple logo will be displayed for the split second then a black screen and nothing else. This happens when it's plugged in to the charger as well. Unfortunately it's no longer covered by Applecare but I'm certain there as been no water damage and there is no cosmetic damage to it whatsoever. Any ideas what could be causing this or suggestions on how to progress?
