I suppose it is possible but it's a new one on me! I've never seen one with a spindle motor failure.

Are they sure? Or just spinning you a line!

Just because the CD doesn't spin it is not neccessarily the motor that has failed.

The CD will not spin until laser focus is  found.

It is so uncommon that I would ask them to check the motor again.

I agree.

I've heard the diagnose before but it was always the laser current and/or focus that was off.
If the laser don't see the CD, the spindle motor won't start.
Some decks give a tiny jerk with the CD if they don't get a reflection at the first beam of the laser
in an attempt to rotate the CD away from an eventual dark spot and then shoot a second beam.

This can happen,but rarely,and only with the later '9500 direct drive dc spindle motor.There are fusible resistors to protect the motor supply in case of motor siezure/burnt commutator etc.If they blow,then obviously there is no motor supply.

I've never had any problems with the earlier induction type spindle motor,fitted to the first generation of '9500.

It seems you could benefit from a second opinion
