Alright Regardless of what I have said I now think it is an HV problem.
Using a fluorescent bulb in the dark I put it near the heavily insulated Hv lines. That go to the suction looking cups on the CRTs. When you flick power on the bulb glows momentarily. I could also see some HV leakage arcing.(Should this happen at all) Then it stops glowing. Once again when you power it off, the bulb glows momentarily.
Also when you power off the projector the CRT's often give there only sign of life at that point with a quick flash. Much like the bulb did when turning it off. This leads me to believe HV failure.
I have a few questions about the HV wires. Do these wires slowly loose there ability to insulate?
Do these wires change resistance like spark plug wires?
Or should I be more focused on the HV transformer area and horizontal deflection sections of this projector?
Any one had a similar problem with solid state?
Thanks for your time
