AX 1500 suddenly broke

We\'ve been using an AX 1500 for two months now driving two motors for a tank tread and today it and a second motor controller suddenly died. We still can\'t figure out how this managed to happen as all the wiring is good and no fuses blew. All that seems to have blown on the AX 1500 though is one of the shottkey diodes near the motor terminals and one of the H-bridge MOSFETs. Is it going to be possible at all for us to repair it? We don\'t have enough time to send it in to get repaired as our competition is in a week.
