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 laser power adjustment is designed for factory use and NEVER resolves a problem with reading the disk. There are adjustments for tracking and focus that can be done, but these units are factory set and do not have these adjustments available in the field.
If the laser is far enough away to avoid dust, can you tell me how a hair can get there? As far as cleaning the lens is concerned, dust, dirt and greasy film from whatever is in the air is a common problem with ALL lens assemblies. Even Pioneer systems that have the lens facing downward are subject to this problem.
"NEVER" is a strong word! Lasers age since they operate at a fairly high power density so if you've nothing else to try, why not?

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.
Keep us posted on your progress.
