Well... so much for working pretty well.
Since getting high voltage back, I've been watching the set for a while. I watched a movie today, and it worked very well. Tonight, I showed it to a friend, and we watched The Simpsons for an hour, and then, while it was sitting at the DVD menu screen, I noticed everything looked... fuzzy... Starting another episode, the blue screen at the beginning of the show bloomed up and got real, real fuzzy. And kept getting bigger. I shut off the set.
After letting it sit for a few hours, I powered it up again. I turned the DVD player and the TV on at the same time, and when the HV came up, the DVD player (a cheap Cyber Home) was still at it's main "loading" screen, which is blue. It bloomed and fuzzed away, and the screen went black. I shut off the set, and let it sit for a minute. Then I turned it back on. This time, it came up with a fuzzy menu screen for the DVD, which is darker, with black at the bottom, not an intense blue.
So... something is wrong. I'll have to pull the chassis again. I'm still on the original electrolytics - I should have checked to see if they were warm when the problem first arose, but they weren't warm before after long periods. The picture never quite filled the whole screen, and the linearity and color were always a little crummy, but it worked. So... back to the workbench. Don't know where to start here.
