Any ideas on how to actually fix this? The system gets no hotter than
it normally does...

Hello,

One other thought that others have not mentioned. I've seen a failure
of the clock circuit being fed to the mechanism fail and cause the laser
sled to go flying to the outside if the disc and the sled drive will
keep going. If left in this condition, it will actually grind the rack
on the laser to bits.

Wasn't the KSS-240A also susceptible to oscillation problems and
wasn't there a kit that fixed this?
