No it is not lamp problem. it must be light tunnel problem.
after lamp there is tunnel for light travel, made from 4 pieces of mirror.
this tunnel is glued. glue tend to break in time so the tunnel is no longer doing its purpose.
open this part of projector, there should be 2 little screws holding it. repair it by reposition mirrors and glue them from outside by little drop of temperature resistant and elastic glue. that's it !

X2 OHP mounted on ceiling fixture. Image is dark on right side


Yes it will have to come off the ceiling. It sounds like the light tunnel has collasped. This is located under the colorwheel. If you can get a new tunnel , be careful removing the colorwheel so no segments break off of it...make sure the new tunnel is pushed against the "lip" before screwing the tunnel clip back into place.

this projector does not have lcd's. it has a colorwheel and a light tunnel. the light tunnel has probably collapsed and needs to be replaced if you have distortion in the middle of the display. if it were to one side or the other or a the top or bottom it may have been adjustable. But wiith it being in the middle, I'd have to say you needed a new light tunnel.

the light tunnel has collapsed and needs to be replaced. it's pretty simple to repair. there are directions on the "tips" part of my profile. so, you can get the part from an infocus service center and do it yourself or send it in to them for repair. either way, try www.avsolutionsny.com. they're really good.

that little glass square broke off of the colorwheel, and it needs to be replaced. that yellow/gray line is from the light tunnel collapsing. both parts can be purchased and replaced by you. if you don't feel comfortable doing it, you can send it in to an authorized service center. try av solutions. they're pretty good. you can purchase infocus parts from them, too.

2 bulbs blown.


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.

1/2 the screen is viewable


You would be wrong. Lamps do not do that. They either work or they don't, they do not cast shadows or give half an image.

What is going on is the light tunnel has failed. It is a small, 4-sided mirrored tunnel that focuses the light into the optical chamber. It is directly behind the color wheel. I've seen this probelm dozens of times.
