My iPod Touch 2G screen is black. I know that it's on because when I try plugging it into the wall charger, it makes the little noise that it usually makes, and when I try plugging it into my computer, it gets recognized by iTunes and syncs my music and whatnot. I have no idea what is going on. It's not jailbroken or anything, just on the normal 2.2.1 firmware, or whatever the latest one is. Is there anything else I can do to fix this before having to restore it?
