I am running into a small problem when displaying 1080P sources on the 8500 Marquee. Any idea why the projector occasionally shuts down it's High Voltage to the tubes when displaying this resolution? It almost seems like a thermal issue. It works for a while initially (say 20min) and then starts to shut down and cycle back on. If I display 1080i this never happens. I have both a HTPC and a Pioneer BDP-94HD Bluray player run through a HD Fury and both do the same thing a 1080P. When the picture goes away, I can switch to another source at 1080i and the picture will come back and stay on. When I do this I hear the HV turn on to the tubes (crackles). From what I have heard this PJ should be able to support this resolution, and when the picture does work it is excellent. The Marquee has had mods done to it to support anamorphic width and also has HD145 lenses. The picture size is maximized on the tube face and most other settings are at nominal/mid levels for phase, brightness, contrast, focus, ... any ideas?
