I have a Sony 5 disc CD recorder (RCD-W500C) and a few times the last couple of weeks it's gotten stuck while playing a CD on one of the ports on the playing (as opposed to recording) side. The time (on the display) stays the same and it keeps playing whatever's at that point. It's happened on at least a couple of discs. I'm starting to keep track of this - which port, how much time is left on the disc when it gets stuck etc. - to see if there's a pattern before I call for service. But I was wondering if something like this ever happened to anyone and/or anyone has an idea what the problem might be, how easy it would be to diagnose and fix, etc.
