JVC model RC-X3 CD portable system

[ian field]

Is there a common stock fault that causes the CD spindle not to spin?

TIA.

Try spinning it by hand, and put a drop of oil on the shaft with a needle
oiler so that it drips down the shaft into the housing. Use a fine oil like
wd40 or LPS. If that dont work you can remove the motor, find out its
operating voltage and hook it up reverse polarity on a DC supply set at the
operating voltage. If it wont turn, help it by hand. If it does start let it
run for a while, increase the voltage a couple of volts, then remove the
supply voltage, repeat the process under the opposite polarity. Otherwise
its time for a new motor.

Maybe my question was ambiguous, the spindle is free to turn but doesn't.

Does anyone know if the likely cause is something simple like a sensor
switch or motor PCB fault, or is it likely to be something more involved
like a laser fault shutdown mode?

More often than not - a bad laser pickup. The laser / focus circuit must
achieve focus before the disc will spin.

Not been following the thread, but obviously if the lens hasn't been cleaned
yet, now is the time. Seen lots of bad JVC pickups, though...

Knowing my luck it will be the latter!
