Dead iPad3. Recovered it in iTunes, but still the display is dead and it will not work.

Question

My ipad3 will simply not work. It froze and the display went black.
I've tried to recover it by putting it in recover-mode and connect it to itunes on my computer (Windows 7).
Itunes found the ipad and the recovery worked out fine (according to iTunes info the ipad battery is charged 57%).
However, the ipad still will not switch itself on? I have tried the on/off and home button trick as well as the recover in itunes.
Any other tips?
