Q: I have a 3rd Generation 20GB iPod that is almost full. I have recently started having some screen issues: when I first turn the iPod on, the screen is jumbled.
Usually the problem goes away after a minute or two. Is this caused by the processor having problems reading the song catalog? Or does it sound like the iPod is defective?
A: The easiest way to test for catalog corruption would be to wipe your iPod’s hard disk (using Apple’s Software Updater) and then use iTunes to replace all of the songs.
This has worked for some people, including us, when an iPod starts to act up. If this doesn’t make things better, your iPod probably needs to be serviced.
