Check the ICPs on the "main" board (not the system board but the driver board. I've seen those blow causing motors to not function. Our guys keep a few on hand to solder in the field.

if you've tried changing all of the obvious i recommend updating the firmware. i had the same problem, changed the dev and dev tank which made no difference. my colleague went in, updated the firmware and the machine has been ok for a few months now

Probably control board, 51-4 points to the board and 0005 at l detect points to control board.

Id try the easy stuff first like making sure the dv motor turns...
