I just repaired a CD-Rom2 with a new gear, and can confirm it moves correctly. When I place a disc on, the laser tries to read but just continuously makes a clicking sound.
It seemed the disc was constantly scratching so I tried prying the spindle up a mm or so, and I get
mostly the same issue. No spinning, just an attempt to read the disc but no movement, and continuously clicking with out engaging.
I'm thinking of moving on to caps, but wanted to see if anyone knows the proper laser height. Is the spindle hub supposed to be flush with the white metal CD cover that protects the laser? Thanks
