AppleCD SC Not Working

[Zhinü]

Got an AppleCD SD that doesn’t seem to work. I took it apart to find that it didn’t have the usual leaky caps, however it also doesn’t seem to read CDs. Put in my Apple Legacy CD (the 7.6.1 variant) that I burned to find that it flashes the orange light up front twice before slowly spinning the CD backwards. If I put in an audio CD, it does the same thing but stops the CD after the two flashes. I tried cleaning the lens with rubbing alcohol to no avail.

Any fixes for the units that don’t have bad caps?

Any pot you can adjust on the laser lens? Also check belts

I believe there are a couple adjustment pots but I do want to wait till I get more advice before I start tweaking those. AFAIK these are old enough to not use belts.
