I have Projection monitor Mitsubishi 50P-GHS91B that has no video. It is in a Confidential Mission Deluxe. Video feed wiring checks out OK, and have checked voltages on main/HV pcbs, and they check good. Necks on CRTs glowing. It acts like my projection TV at home when I have no video input. So I am guessing the video/sync. section/pcb is bad(I have done wiggle tests), any ideas? Anybody have a manual for this monitor?
Thanks for any info
 
Have you tried cranking up the "screen" controls to see if you get any raster or anything on the screen? I think this is the same model that's on my Top Skater, but fortunately I haven't had to work on it. Otherwise, have you made sure the impedance and video level switches are correct (if they're there), or any of the user controls (I don't remember if there's buttons on the front, or if you have to use a remote control). It sounds like it can't be too far off though.

Hi,
The only controls I can find are screen and focus(for flybacks). I did try adjusting, but got nothing, no raster lines, no change on screen. I believe all controls are done with a remote, which of course is missing. Like I said tube necks glowing, voltages check out, at least what test points I can find, but no picture.
Thanks
Aaron
