My Sony HST-V202 hifi system has a dual cassette deck and a few months ago, I accidently left slot A on rewind after having to answer the door. When I remembered it and went back to it, it had blown the fuse. I recently decided to try to get it working again and I replaced the fuse and tried it, the radio, CD etc all work but the tape player did not. Suspecting I had burnt the motor out, I spend 2 hours dismantling the entire system and removing about 50 screws just to get the motor out, only to find it works perfectly when I connected it across my bench power supply.

Anyone have any suggestions as to what else could be wrong, it seems to be an electrical not mechanical fualt as the motor did not turn at all when in the tape deck. I think it could be a power transistor that has overheated and blown as the motor is quite powerful so it would need something like that to drive it. Slight probelm though is that I can't extract the PCB that the motor wiring goes to, but I should be able to get around that.
