Try pointing your soldering iron at a different target.  I had a similar problem
with our club's 1040.  Turned out the problem was a bad solder job on the PS'
circuit board.  Try resoldering the points where the leads from the transformer
connect to the board.  Based on what I saw with this unit, I would likely 
re-solder all PSs I come in contact with...  To be sure, check the 12V to the 
drive; you may find that it is either low or non-existant.

Good luck.
