No Sound but all clickwheel functions seem to work

jayp, this is a copy of one of my answer to a very similar question. May be it will help you. "This particular model has a problem with an IC on the logic board. You can try and see if you get sounds by applying some pressure to the right lower side of the ipod, almost between the click wheel and the bottom corner. If you should get sound by doing so, then you only have very few options. One is a new logic board for about $40 on eBay; the other one is to reflow your old logic board. Or you can try what warnergt did on http://forums.macnn.com/103/ipod-iphone-... By now I can verify that this works since I performed a reflow on three of the boards and it solved the problem. The logic board is available at ifixit as well as multiple other places. Good Luck to you and your iPod and rock on....;-)
