Hi, Might it be the lens? The exposed portion of the lens do get covered with grime and dirt, maybe not much but when used, it gets baked because of the heat from the lamp. Cleaning it by wiping is not enough. You have to use a solvent to really clean it. One thing to remember is to clean it when it is at room temp and not after use (even a short one). The sudden change in temp is not that healthy for the lens. Since you were able to change the lamp, perhaps you can also do the inside portion of the lens. Treat it like your eyeglasses or the windshield of your car. Sometimes you really have to rub on it hard to remove the stains and smears. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

My lamp light is yellow green? what could be the cause?

hi ,
Do one thing just reset the lamp hour of your projector. For resetting the lamp hour do the following.

While simultaneously holding down the Right arrow ( >) button and Auto sync button on the projector press Power ON button and Left arrow ( button . The lamp hour will indicate zero.
If doesn't work you have to replace the lamp.
Remember on thing Lamp hour reset is recommended only after the lamp replaced. so try to replace the lamp if it work after the resetting procedure.

Infocus X2 projector shows picture in black and white only...

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.

I am having the same problem and am looking for a solution.  I do know what is causing it however.  Between the lamp and the lens system there is a small square tube made of mirrors that are glued together. One side of the mirror has come loose and is in the line of the light being projected by the lamp.  I have attempted to fix this by reglueing the mirrors, but it doesn't take long to fail again.  I am trying to find a replacement or an upgrade, maybe polished stainless.  The part is small, made of some type of plastic and cheaply made.  I am disappointed that such a seemingly insignificant part could be the root of such a problem.  Not impressed.
