Is the unit shutting down or does the screen go dark and HV still present. I find that most probs with this set are bad vert out IC , Bad connections on the pc board on the yokes at the tube or fluid leaks on the PCBs. hope this helps.

You hear the HV come up then unit shutsdown. I'm not familar with this chassis and dont have a service manual. Any help would be appreciated.
