I read the FAQ, did a number of tests to no avail. I put the repair
project aside and finally got back to it last weekend.

I thought I would post my fix - in case this info is helpful to
someone else with similar problem with a Pioneer PDM600.

There is a plastic assembly which clamps CD to motor from the bottom
side of drive assembly. On the plastic assembly a small metal ring is
affixed and clamping occurs when it is attracted to the magnet on
drive motor.

In my broken unit, the metal ring had loosen from plastic assembly and
was stuck to directly to the drive motor. Thus, the metal ring was on
top of side of the CD, the CD was never clamped in place, focus was
never achieved, and disc did not spin.

I used a small amount of model glue to reattach metal ring to plastic
assembly and unit was restored to service.

Thanks to all for responses and ideas how to fix the unit.
