yep. power supply
if there was a short in the driver board then you would have 5V on right side and 0 on left side with the driver board connected
easiest thing to replace is the transistor on the power supply board (no soldering required)
replace it with a 2N6059 transistor.
could I the transistor at Jaycar?
also do you know the what type the capacitors are off hand?
thanks again for your help
