Question about Optoma HD72 Multimedia Projector
Power supply for the lamp got me an extra 600 hours... I have changed bulbs gotten 1000 or so hours from new bulb. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

you won't find schematics for them. infocus had their boards made by someone else who now no longer makes boards. it's usually the caps drying out that causes power problems.

This problem is more likely to be the Green LCD gone. The green LCD's job is to filter out the green on the picture where it isn't necessary so If the green LCD starts to fail, it will let through too much green light. I think its more in the middle because of the heat from the bulb over time.
