This seems to happen when the guns are predomantly showing all white then the screen changes to another scene that is darker. The g2 then carries back to pure white slowly. The g2 adjustment will help some to stop this but never fixes it. The g2 on these sets are really finicky. Only 1/8 turn in either direction will will either make the screen dark and muddy or shut down the set. Can't find a happy medium. Is this a weak CRT? I'd check it but can't.

I'm afraid you indeed already know the answer
. But have you done a setup on that tube? There's a procedure to set the G2, and several other critical adjustments, which really needs to be done by scoping for true peak to peak DC. In fact, if not done right, it can hotplate the CRT and weaken it fast. If you don't have the book, I might have it... It's worth doing, as that will tell you exactly where you stand on that tube. And there's still a spare KV-40XBR sitting on a flat dolly around here someplace ;-)
