Pls check if the lamp is not so old that is giving the same problem. If lamp is almost new, then you can have a check with the Ballast unit card and then the loose connection in the Power supply or may be overheating and tripping.

SOURCE: color problems
i don't know if this will work but..... I have an Optoma h27 and we were having problems with the color and ours is mounted on the ceiling in inverted also; and after two years we started having color problems, come to find out that on the menu there is a option for high altitude and that had been turned to the "off" position (probably by our kids resetting all the options and not turning this one back on)..... after taking it to a tech that cleaned it for $97.00 and said there was no problems he could find, we played around with the remote/menu and came across this high altitude option and when we saw it was on the "off" position, we put it to the "on" position and another fan inside the projector came on and that helps to keep the inside of the projector cool at all time and helps from the color becoming weird..... Try this on yours and hopefully that will solve your problem.

1 - Hold the clear tv buttom until all 4 light flash red
2- Press the red tv buttom
3- Press the amount of time needed on the up cursor ( around select buttom) until your tv shut down
4-When the tv goes off press the search buttom ( at the end on the right side )
Then u can use the red tv buttom to control ur tv and u can control the volume on satelitte mode without going back to tv mode , if u press too much time while searching the code and the tv wont light back , do the same thing but instead pressing the up cursor press the down one to go back on the code it will be faster .

It's not a short, the blub is near the end of it's life ~ the optoma is designed to detect when the blub is about to blow and shuts itself down. Turning the projector upside down or right side up usually only gives you a brief reprieve (some have reported a modest amount of extra time gained) on the blub ~ but in the end it's on it's way out and the projector will shut down again.

i'd say power supply issue, but the led is blinking green. this means that it thinks it's in warmup/standby mode. but if nothing's running, the main board might be bad and needs to be replaced.
