Sony PVM-1220
I'm having a problem with the pin circuit. I replaced some bad caps with no change. I'm suspecting the pin driver (PNP signal type) or output (SG613, horrors). I have no schematic. Nice pin waveform on the base of the driver horizontal only at collector, emitter and gate of the output. I have swapped the driver yet or measured all the discreets out of circuit as I just got a new desk and had to tear down the computer system but I'm back up and running now and don't feel like it's all going to end up in me lap. So, what should I look for or replace? Or does anybody have a print for this or similar? Thanks!
