CD player won't play
CD part turns on and door opens but won't play CD. Can this repaired?
So the CD spins? And after a few seconds the display says No Disk or something similar? Probably a laser problem. Unfortunately in my experience it’s rarely a dirty lens as it’s tucked away out of the way of dust, but certainly check for any stray hairs on or around the lens. But take EXTREME CARE in cleaning the lens as it’s suspended on very fine wires which are easily broken.
If you can gain access to the optical assembly you should find a laser power adjustment somewhere on it. You could try turning it clockwise by just a very small amount, but this is kill or cure - you probably need test equipment worth thousands to set it properly.
You could try putting a search on eBay for one with a different fault offered as "for spares or repair”.
The answer is yes, but whether or not it is economically feasible is another question. If you can gain access to the laser lens, try gently cleaning it using a cotton swab and alcohol. Sometimes a buildup of dirt/dust can interfere with the laser and prevent the unit from reading the CD properly. If that fails, the next thing would be to replace the optics which may not be available as a separate part. These units were not designed to be repairable.
