Hi guys, I have a problem with a iPad 2. I bought this thinking it just needed a new digitiser as it was advertised on eBay. When it arrived it was working. Replaced digitiser (that came with it new) plugged into charger and it started going into a loop. Charge battery sign then Apple logo the the cog then blank. Now after playing around with it I can get the charge sign and the apple logo but then goes blank and does nothing. Not reconised in I tunes. Help me pls.
