[SIZE=10pt]Listen to see if there's a slight beeping sound coming from it. If there is, than it's just the screen that broken, but I don't know what to do if that's the case. If it isn't beeping, then the battery could be dead. But before you change it, move the battery around a bit, sometimes its only slipped out of place. Of course if that doesn't work, go on and change them. Remember to download (reset menu and select download) after fixing it. I hope this helps!![/SIZE]
