Al,
We test on bench nothing hooked to chassis, check voltages, before sliding
back into cabinet..Maybe something shorted.. We replace the caps in horiz
and yoke circuit, some times you can see slight bulge, in some of them.. If
you need C#'s i can look up and send them to you... WOW... Samsung 29V
relay closed...

> This came in with the HOT shorted. Replaced HOT with OEM and Damper diode
replaced caps in power supply. Standby voltage is correct. When power button
pushed high voltage starts to come up but stops at 5K, Regulated B+ is ok.
Now here's what I tried. I took the horizontal yoke plug off and high
voltage came right up, then shut off then right up again, then poof went the
HOT.My question is by pulling the yoke did I Change the timing for the HOT
enough for it to run without shutting down or do I have a bad yoke? Yoke
rings 17 rings GOOD. Fly rings 27 rings GOOD. I don't have another HOT so I
have to find the answer.
