Have you tried rebooting? Pulling the battery?

Can you get to recovery? Usually a series of button pushes from powered down does this. Try holding both volume buttons + power... Or Volume up + home + power...

If you can get to recovery, factory reset. You loose your data, but hopefully you have some cloud backup and your device may work again.
