in order for the lamp to strike and stay on, the fans and the colorwheel must be spinning and up to speed. if you remove the lamp and start it up, see if the 2 fans are spinning. and look inside to see if the colorwheel (a colored glass disk) is spinning. you'll also be able to hear a high-pitched squeal coming from it. unfortunately, you'll need to take it in to a repair center to have them replaced.

Have you tried another lamp? Sometimes thats your problem, but I've seen a several occasions that the a defective power supply causes this symptom. Do you see an image flicker before the projector shutsdown? I do have some spare parts for this projector.
I'm on Ebay - gtitubro if you want to contact me through there.

if you don't hear a high-pitched whir, your colorwheel needs replacing. you can remove the lamp and see the colorwheel inside (colored glass wheel). if you turn it on without the lamp, the colorwheel should still spin. if it does, you have a ballast problem. if not, the colorwheel. you'd still need to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.

Testimonial: "i understand what the expert is saying and this information is very helpful"
clean the dust out of it with canned air. the dust keeps in the heat that the projector is trying to expell. it also shortens the life of the lamp.

the light tunnel is collapsing and need to be replaced. you could get the part from an infocus service center and do it yourself or send it in to one and have them repair it. speaking from experience, it's a quite involved repair. you have to basically take the whole thing apart to get to it, and make adjustment to it really close to the power supply while it's on. kinda risky. either way, try av solutions in ny. they're really good. www.avsolutionsny.com
