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
