I have a nice 2465B that I bought as being fully restored and recapped (I’ve not opened it up yet but have no reason to doubt) that only has about 460 hours on it. I bought it back at the end of the summer but have only put maybe an hour and a half on it since; I turned it on a couple of days ago and it had a perfect display then suddenly everything disappeared to a diffuse glow off the right side of the screen (UL to photo album "2465B screen issue") After about 5 minutes it snapped back to being correct and stayed that way for another 30 minutes until I turned it off. I turned it on yesterday and it worked perfectly for about 15 minutes then went back to the fuzzies and has not returned to normal yet. Note there is no gradual transition between states, it is as far as I could tell instantaneous. When the display was working it had a perfect, sharp image and passed all self-tests. The problem is obviously (???) in the CRT/display circuitry, but I have not opened it up yet to check anything – I was hoping to find someone that might be more familiar with these units prior to starting.
Any hints and advice are very much welcome.
