iPod Video No Sound at All

@newtonian first you should tell us if it syncs properly and if you can access your files with music while the iPod is in diskmode. After that you want to place your iPod into diagnostic mode and see if you get any errors (you may get a FW error). If none of that shows any issues, you may have problems with the audio IC. In the case of your iPod I am leaning more toward this problem. 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, 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 of course available at ifixit as well."
