Follow the instructions to remove the lamp as if you were going to replace it. Mine did the same thing today at about 1200 hours. The lamp has two screens on each side of it. Mine were dirty and there was signs of excessive heat on the front side of the lamp. I am 100% sure mine ate craps with no warning and the dirty screens are to blame.

How old is it ? Approx how many hrs have you used it? Was it set at Lo speed / low power or hi speed / max power on bulb and fan? Do you smoke in the same room? Is the unit ceiling mounted ( more concentrated hot air ). Have you had a power failure while the unit was on? The bulbs used in many projectors , although claiming 3000 or more Hrs ,are subject to early failure. If the unit or bulb is new ( less than 1 yr. old, contact the service manager at that co. and complain about short life; IThat works !

How do i find out if i need a new lamp for my infocus 4805. when i turn it on the fan blows for a cpl secs and the green light blinks a few times, but i dont get anything saying the lampis out


when you power it on, do you hear a high-pitched whir? if not, you need to replace the colorwheel. it's also the colorwheel if you hear a buzzing instead. if the colorwheel does not spin, the lamp won't come on. if the colorwheel is ok, check the lamp. is the screen on the side of the lamp clogged with dust? is the inside of the lamp bulging, spotted, or foggy? if so, replace the lamp and clean out your projector with canned air. dust blocks air flow and keeps in the heat. this shortens the life of your lamp and projector. if you do need the colorwheel replaced, you could get the part from an infocus service center and do it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Light went out


then it may not be the lamp, but make sure you have the right one (sp-lamp-021). also check to see if the colorwheel is moving. turn the projector on and listen for a high-pitched whir. if you don't hear one, the colorwheel needs replacing. and the lamp won't light without the colorwheel spinning.

Sound like either the lamp has prematurely failed or the lamp power supply ballast or igniter has failed.

Infocus 4805 blinking red light problem


My first questions is:

Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.

Let me know so I can help trouble shoot other possible problems.

Infocus 4805 projector


There is a cooling off period that your projector will do in order to make sure it does not implode or improperly destroy your lamp. It is very fragile and each time you turn on your projector it lights up almost like you would light up a candle. Each igniting of the lamp creates a decrease average of 3 hours per turning it on/ff.

also, have you tried another lamp and reset the hours, or cleaned out the filter at all?

Let me know how things go for you. I wish you well and hope that helps fixes the problem.

Projector stays on for 3 minutes then turns itself off


Hi Chipped Rice

The loud buzzing noise you heard was the colourwheel that gave in.

Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.

You will have to replace the colourwheel unfortunately as it cannot be fixed.

Thanks for using Fixya !
