Infocus X2 (by 3 users)

I can almost guarantee that your bulb is out. We probably have 20-30 projectors of this model in the school and bulb life averages a little over 100 hours even though they advertise 3000 hours. Infocus has been known most for their poor cooling system to the bulb over the years and most owners won't get the life expectancy of the bulb. If you remove the bulb you will find a small restrictive vent screen on the bulb and commonly it will be filled with collected dust. This model really doesn't have any removable/cleanable filtering system installed - again a cheap and poorer design then many other brands. We have decided not to purchase infocus projectors anymore in the district. They were a seller at one time because they were cheap, but because they don't last they weren't really a deal after all. Sometimes though a ballast for a projector will go out and it will be unable to power up a good bulb. I wouldn't consider fixing it because of their overall poorer reliability.  If your looking for a cheap but more reliable brand of projectors I'd steer towards Epson projectors. They tend to have lower costing projectors and bulbs then most and I have seen in person that they last well above their advertised lamp hours in different models. Their are many good brands out there but InFocus is not really one of them - they have under built projectors and poor phone support. 
Hope this helps a little. - Scott
