iPod broken

Well my 30gb video ipod is broken. It was acting really weird for a while, I kept having to do hard resets and it would come back. Then one day it just wouldn't do anything, so I ordered a new battery off ebay. I replaced the battery and still nothing. I came across a post that said you need to put a businesses card inside to add extra pressure. To my surprise this actually worked, I couldn't believe it. It only lasted a week though, now it won't come on again. I think the logic board is going out, but have no real idea. For now it's just a paper weight that stares at me and laughs :-(
