Ahhh - tonight I made a discovery - and I think my CD5500 is toast! I noticed the heatsink was extremely hot. It's the MC7805 +5v Regulator - it's cooking! I disconnect the laser controller board. The regulator is still cooking! I measure the input: +8.75v - the output: +0.7v!! I remove the regulator and test it - it's fine with 5v out from

Hi martin Sorry for getting your ID mixed up! Thanks so much again for your advice - can I make a donation for your help? I would dearly love to get my CD5500 working again - it's been too long since I heard it running :-( OK - I removed and measured both resistors - both are measuring 10 ohms. I replace resistors. I checked voltages when play is

Die - thank you for your reply :-) I must have the later version as the drive motor connector only has two wires - black and grey. However I measured the output after pressing play and the output (pin 2) is a mere 0.56 volts. Pin 4 (not connected) measures 9.2 volts. I will try to get the scematics as this seems to be deeper than I thought :-( Any further

Sorry to bump this thread back up! I seem to have a similar problem :-((( My CD5500 is powering up - and the tray mechanism is working fine. However when I insert a CD and attempt to play it - The Track light illuminates but the CD motor just twitches around - say a tenth of a turn and stops.... You can give it a gentle helping hand and it will spin
