sounds like the little button the logic board stopped working. It's a easy repair, but requires a new logic board. They run around 75-150 bucks online, the price of used ipod 5G, typically. Try craigs list or ask around if anyone has an old dead 5G ipod. Make sure its a 60 or 80 gig as that board has extra ram for larger libraries. The hard drives went out on those all the time and just pop your hard drive into the broken ipod and bingo. New ipod.
