I have a 32G iPod Touch that is about 6 months old. Several days ago I put it into a new carrying/protection case and the brightness feature seemed to stop working. I put "Brightness" onto max and tried turning "auto brightness" on and off with no improvement. Is there something else I can do to get the background bright again. I can still use my iPod touch, but can not see it unless I have a bright light. Thanks.
