Scott; all standby voltages have to be working properly for the 5 volt
line to work, do you have
a solid 11-12 volts on pin 16 of U4101? 15 volt line at CR4118`s
cathode? Approx. 165 volts
on the collector of the chopper transistor? Approx. 140 volts (cold
ground) on the cathode of
CR4116? Give us more info and we`ll be able to help you more, Larry E
