32 GB ipod touch can't get rid of white screen. Tried all of the suggested reset options I can find including the button reset procedure and connecting to itunes. Button reset only yields white screen again as does the itunes reset. Some troubleshooting sites I've found say that the slider and touch buttons still work - not in this case. In itunes i've upgraded to the latest firmware and can transfer files to/from the ipod. It does make the typical noise when connecting/disconnecting from the computer. Replaced the LCD and primary screen to rule out those components but still have the same issue. Logic board?
