I've repaired a number of their changers over the
years. A common
fault (and not limited to just this brand) has been the leaf contact
switches that detect the open/close positions of the tray and disc
positions. If the changer thinks the tray is open, it's not going to
spin up the disc.
Not the problem. It does other things that it wouldn't do without
being at least prepared to spin up the disc; it lifts the reader
mechanism into place and seeks the laser/lens assembly vertically (ie,
parallel to the disc spin axis). It's possible that the laser and/or
light sensor (phototransistor?) is what's dead, and it's not spinning
the motor because it thinks there's no disc present.
Any chance your particular changer uses an indexed
contact system to
detect which disc is present at the reader mechanism?
No. The tray has holes next to each disc's tray position, in a pattern
fairly obviously related to the position number. This also means that
the tray position sensor inherently senses the actual tray position,
regardless of whether it was reinstalled rotated from how it was when
it was removed.
If you do have a bad motor, replacements are fairly
easy to come by
(email me if you have trouble finding one if it does need replacing).
Thank you; I'm not yet sure it's the motor, but if I am and have
trouble, I'll drop you a line.
