This happens rather easily causing the drive to not work.After running for another 4 hours the cd cut out again and I can't get it to spin anymore, I did not touch the pots which were near perfect. What strip are you referring to, did I overlook a pic in the repair thread?
I typically just remove this strip since it isn't needed.

Quote from: LowRes on 01/15/2018, 04:37 PMThere's a sticky in this section with a excellent guide on how to adjust the pots by ear on a duo. Follow the guide and hopefully you will get discs to spin again. If you marked the pots before adjusting, I'd return the pots back to your mark and start from there. Either way the guide should get you running again.Keith nailed it as expected
also I'd make sure the gears and rails are clean and lubricated
, blasted cables.I re-did the pots to match the multi-meter readings for my pce duo and slightly adjusted 101 and 103 to get it fixed fast.

, you are on to something, after fiddling around and double checking the wiring it brought it back to life, now to run it for a bit... this makes sense sicne this started after i last closed the unit.

Console Repair/Mod Center / TurboDuo CD drive no longer spins

Hi,
I recapped a TurboDuo and tweaked the pots to fix the audio track glitching, ran it for a 4 hours and when I closed her up and did a sanity check the CD no longer spins. Did the lens burn out or the motor die? I tweaked VR101, 103 and 105 slightly to fix the glitching/skipping which got it working perfectly... any thoughts?
UPDATE: after leaving it off for a bit i measured the voltage on the motor (4v) then it started working for a few minutes then stopped spinning again. Initially I could finally hear the lens try to adjust and after a few tries it spun and read audio for a few minutes until it died again.
