The CD System from Panasonic is "old" equipment, but was working fine yesterday. Today the CD won't play. The tuner and cassette deck both work. I troubleshooted with the manual with no luck. On the display panel the "over" mark is lighted. The CD's I played yesterday were in bad condition with lots of scratching. Could that have caused the problem? Hope someone out there has a solution-other than buying a new system.
