while watching some videos, the projector would suddenly cut image, then come back from blurry and dim to sharp and bright. then one last time it did that same trick, and from then on has had no image at all. I am getting nothing that looks like an error light from the system. have power to the fans, can turn the unit on and off, and when on, I get the full complement of fans.
Am I likely looking at a HV PS? or another board somewhere?
with "reasonable" digitals well under 1K.... this may be my final push
those are certainly the symptoms of a dying HVPS. Considering used ones sell for $250. I'm not sure I would invest that into an 8000. Not unless the tubes are good, it's a newer late-model 1994/95 version, and you already have and HDMI converter (moome card or Fury) .
If it's an ancient 8000 with the fixed rear heat sink that doesn't hinge down and your running some kind of line doubler or momitsu player I would not fix it.
BEfore you write off the HVPS, reset the H deflection board, the one between the G and B tubes. The HVPS can be changed out with the set on the ceiling.
it's a keeper, there will be some 8500 parts in there for sure. Also be aware that a $1K digital will not be the perfect new display your hoping for. The really good ones like the JVC DILA's are still $4K + if you can find last years model on close-out.

Still not sure if Imm going to repair it. Don't you have to drop the projector from the ceiling to replace the HVPS?
maybe send your old one to the same person if they can test it. Tim can for sure
try and find a newer V3 (version 3)
