I believe that's an overheat problem. Check the fan if it's cooling properly. Make sure the unit is in a cool temp room.

I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

No light and some fan noise


Take the top off and verify that all of the fans are on, there are 2 behind the power supply and one behind the engine. If the unit lights up when the top is off, then the wires above the dual fan assy may be putting pressure on the fan frame while the top is on causing one to rub or not turn at all. If this is the case, unplug the power and try to route the cables thru the notch in the top of the fan assy a little better. If any fan isn't working, the unit will not light. This could be due to a main board problem or a bad fan itself. If the colorwheel is stuck, the unit will light and then shut off. Also, depending on the age of the projector, if there isn't a green wire going from the front of the main board to the bottom of the power supply ballast, the power supply will need to be replaced or upgraded by a technician.

Just replaced projector lamp, but the new lamp will not work. I noticed the fans in the projector are not running but the color wheel is. The green power light flashes. Can anyone please help ?


make sure the fans are connected. if they are, listen for a low sound like a chuuuurrr,chuuuurrr, if you hear this sound then it is highly likely that the main board is bad. Oh, and make sure nothing is keeping the fans from turning.

if you hear chirping or a loud buzzing, you have a bad colorwheel. the lamp won't turn on if the colorwheel doesn't spin as fast as it needs to. if you don't hear anything like that, you need a new power supply. the lamp striking takes a lot of power, and if the power supply can't handle it, it shuts off. you can get the part from an infocus service center and replace it yourself, or send it to them for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

I have a proxima s540 ultra lite data


From what you describe, it sounds like a fan isn't working. When you turn on a projector, it will go through a quick self test--checking that everything is operating correctly. Some of the fans send out a signal to the main board telling it that they are running. If no signal is received, the board senses this and auto-shut down occurs to protect the unit from heat damage. The errant fan could be spinning but the computer pulse might not be being generated. It will require a tech to find this out.

Only power light will power on for few seconds then flashes.


Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.
