It's either something mechanical, the motor is bad or bad bearings etc on the exposure advance unit. Does it turn freely by hand?

If it is not mechanical, and you are sure the wiring is all good, the problem will be with the PM driver chip on the I/O PCB 1 J391483

I recommend you check the resistance of the wiring from the I/O PCB 1 to the connector J/P345 just to make sure everything is good. Circuit drawing is attached.
