As I understand the operation of this animal, it sound like you have either a failure of the oscillator IC (PD1003) or one of the motor IC's, specifically the IC PA2005. You need to check the output at pin 15 of the PA2005 IC. It should give you 10V. If you don't see that you either have a bad IC or bad component feeding into that IC. If the output for PA2005 is good, you need to look at the oscillator IC. Pick up a copy of the service manual. All of the above is outlined.
Thanks for reply. I measure voltage. Check all components near PA2005. Nothing abnormal. I've done little adjustment of speed trimmers to obtain perfect picture on oscilloscope. After assembling unit problem never back again.
