Trays work fine, detects LD but won't spin up (LD/CD) properly.
Ribbon connecting the optical block to the motherboard needed re-seating.
Now Side B plays but not Side A.
Adjusting the Tilt for Side A didn't help.
Spindle height needed to be adjusted and Tilt for A and B adjusted as well.
Chassis also required some unbending to avoid the discs touching it (making these weird sounds).
Good job!
