Also I was looking at the Servo/Control Board for this VCR in the Sam's and it seems that it does indeed control the take-up and supply reel motors as well besides the capstan and drum motors.
So again I think I might take a look at that board for some bad capacitors with my ESR meter. |
You can measure the junctions of the transistor in the diode test mode of a multimeter. I don't know if this model is supposed to run the supply and/or take-up reel motor when you turn it on as we didn't have a PV-1730 equivalent model here in Europe. Does the front loading mechanism accept tapes?
