I had a toshiba sd-3109u DVD player come in that would not play.

hear the laser trying to focus, but NO platter motor spin.
Took the laser sled out (79070415). If i put 3 to 5 volts on the
motor,
i could get it to spin if i helped it start by hand. But even then it
was drawing over 2 amps so something does not seem to be right.
the numbers on the platter motor are CL903T C9316A.
It seems to have a hall sensor on it too. Anyone know where
to get just the platter motor?

Ignore those other gues. Sure, throwing it in the trash may be what
eventuall happens, but there's a lot that can be checked out first.

If it's a normal permanent magnet DC motor, try a quick spray of
degreaser through the holes in the back to clear the crud off the
commutator.

These motors are _really_ cheap crap. Having said that, yes it's often
possible to clean the crud out of the brushes. It requires a knowledge of
how these motors are constructed, so that you would know where to spray the
cleaner in through the slits on the bottom of the motor, a compressor is
handy to help blow out the crud and any excess cleaner / lubricant. It's
often necessary to repeat the process numerous times before the short is
cleared.
