You didn't say if the laser was turning on. Can you see red light emitting
from the lens? If yes then it is probably weak, if there is a pot on the
laser assy try turning it a small amount CW or CCW to get more output. Also
it may not spin up fast enough, with a CD in it should spin up too fast then
slow down as it tries to focus and read. Weak laser and slow spin motor are
common problems.

I defeated the CD door -down switch so I can see the laser moving
up/down about three times trying to focus, and the platter is
spinning.Also the laser slightly moves left then right on it's track,
then stops and displays "no disc". Track numbers always say "00". Never
detects number of tracks.
Bad laser?
I cleaned the eye.
Need input from more experienced CD audio techs.
