    I have same problem after 1100 hrs on my bulb.

    I bet the fan is also causing my over heat condition.

    Will try cleanning lens and filters first next week.

    Will try to replace fan on my own if that doesnt work.

    Thanks for the tip.

I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit. Good luck.

I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.

It sounds like there is a fuel flow problem. There is a restriction either in the tank or fuel filter that lets enough fuel through to start the engine, but not enough to keep it running.

Did you figure out your KVM?


if you tried to connect your mouse to the keyboard port and still it doesn't work. Power cycle meaning unplug the KVM from the CPU, monitor, keyboard and mouse. Then wait for about 30seconds before reconnecting again. If you still encounter the same problem that the keyboard port won't work then it means that keyboard port is defective. Replace it.
