Well, you could wait for the battery to die or try forcing a shutdown. You can force shutdown by holding the power button for 15~30 seconds. I've had the screen "black out" a few times and a restart like this seemed to do the trick, although I didn't have any sound, so there's always the slight chance of an issue with your screen.
