CDM-4/36 in a NSM Performer Grand jukebox

[MarkInAz]

So my CD jukebox is sick.  For awhile it has been giving me trouble with some 800MB music CDs.  It used to play everything just fine.  But lately (2 years) it would only play the first half of some, not all, disks. Eventually it stopped playing any disc, resulting in an error code 61, no disc detected.  I read about common issues so I replaced all the aging electrolytic capacitors on the servo and decoder boards and  performed the laser current and focus adjustments using my voltmeter. Success! It was working again, but only for a few months. Again it started acting up, presenting similar symptoms.  However, this time the current and focus adjustment did not help. The present symptoms are this: only the first 10 seconds of any disc, or any track, will play. After about 10 seconds the audio output gets scratchy and the disc stops.  No errors, no faults.
