Have you checked with the manufacturer regarding a firm ware upgrade? There was an issue with this at one point. Make sure to contact them directly. They can either mail you a cd version, direct you to where it might be on their website, otherwise email it to you.
They are able to fix that problem which my sister and my other sister/brother in law also owned this same pj had to do the same thing.

your light tunnel has collapsed and needs replacing. you can get the part and do it yourself, or you'll have to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.
the light tunnel is collapsing and needs replacement. the part itself is relatively inexpensive, but you have to be careful if you want to replace it yourself. it's under the colorwheel, which is delicate. when you remove the top, front, and rear panels, remove the colorwheel (which is between the lens and the lamp) and carefully set it aside. there are 2 screws holding the light tunnel bracket in place. remove them and the bracket. pull out the pieces of the tunnel (little rectangles of mirror) and replace with a new one. reverse the steps to put it back together. by the way, you can get the part from any infocus authorized service center (check the infocus website for the one closest to you). part # 306-0095-01
check the wireing in the new bulb . My new one had the wires in the wrong holes like if there are 4 slots in the connector then my orignal was in slots 1 and 4 the new one was in slots 1 and 3 so I took the wire out and put it in the #4 slot and put it in and unpluged the machine and did a reset and restart and it came on green. Hope this helps.
I generally fix this by re-seating the bulb housing. Take it out and put it back in. Look for cracking at the base of the bulb on the mirrored surface. It could be a barely functioning bulb that isn't busted, but can't initialize. I would take it to a shop that has the same bub type in a housing and make a quick switch.
To be honest, most people who experience short lamp life on the Infocus X2 is on the genuine infocus lamps. If you read the user opinions here, you'll know what I mean. Me personally think that the X2 lamp filter some how manage to block the vents with dust which results in inefficient cooling in effect reducing the life of the lamp. The best thing to do is vacuum the lamp filters regularly and stick to cheap lamps as the oem ones on the Infocus X2 are also no good. Or better still, just replaace the bulb on it's own from here and save a lot of money.
