I got the parts today. I replaced the burnt 1000 ohm resistor off pin 3 of the HV regulator, and the new MOV to replace the VDR that I was hoping was causing the excessive HV. I can't tell if it made any difference. The picture looks the same, the HV is 27-28kv with the bright/cont all the way up, and still buries the needle (32+ kv) on my probe with bright/cont all the way down.
I got the HV adjustment pot to turn, and it only varies by 1kv from one end to the other with bright/cont all the way up. No change when the probe is maxed out at 32kv.
When I first powered it up, as soon as the HV came up, there was a SNAP and a flash of light from behind, but I didn't see where it came from since I was looking at the screen. I shut it off, got the camera rolling and turned it back on but it didn't do it again. Maybe something was crabby in the HV cage, the cover is still off.
So I'm stuck again.
