I have a panasonic SA-HT 680 and have a confusing problem. My buddy pressed "disk check" and all the disk slots (5) came out of the system and on the display it said please wait. That's it, they all stayed out, won't go back in, and i can't change modes or use the system in any way except to change the volume or change the sound modes and other things that do me no good if it's not working. Anybody have any ideas? I really didn't think that this system would come with a self destruct button built in. I hope somebody can offer me some insight.
