I have a magnavox cdb-650 player that is acting funny. Sometimes it works fine and then sometimes I get this:.... after inserting cd and closing, the display will read error. When I eject the cd, the door opens with the cd spinning at full speed. Do these syptoms clue anyone to where the problem may lie? I was hoping someone familiar with the magnavox (philips) cdb 650 might shed some light in this problem. Thank you.
