10HE Portacolor problem

Finally I noticed the high voltage adjustment pot was laying down on the chassis, so gently stood it back up, powered on once more and it actually came back to life! Must have bumped into the pot while checking voltages earlier in the year. I've been running it for about 3 hours, and it's settling down nicely!

I'm glad to hear your good news. My PortaColor has almost the identical problem. What are the reference designators of the capacitors you replaced? Did you have to replace anything else, or was the cure just those caps?
