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

The Lamp won't strike


if the inside of the lamp has bulges, black spots or fogging, replace the lamp. otherwise, if you have a dlp projector, it may be the colorwheel or the ballast. if you have an lcd projector, it may be the ballast.

InFocus Won't turn off, no powering down, and no projection


The 4805 does not have a power button it has a power switch next to the mains power connector but that switch has no lights near it.
If you meant the power light on the top of the projector right next to the menu button is yellow that is bad. it indicates that the main board is not working which would explain the projector always being on. also the led being orange means that both the green and red led's are on at the same time (this is BAD)
This is not a valid function for the led's. Another indicator that the main board is wacked. By the way if you received the projector less than 30 days ago you can file a claim with the eBay resolution center that the projector is not as advertised/Described in the listing. And you might be surprised when you get your money back! the "NO RETURNS"is null and void if there was any gross misrepresentation or deception in the listing!! i.e. Not as described...

My InFocus 4805 SP projector is showing just black and white


If you have any video at all and it's only Black and white there is a 99.99% chance that your Color Wheel has lost all of it's glass color filters.
You can confirm this by removing the lamp. then look straight into the projector where the lamp was and you should see the color wheel of colored glass segments (Red, Green and blue) I believe you won't see them because they came off of the wheel.
Also if you lift up the projector and turn it around in various angles and you will hear the small pieces of broken glass from the color wheel.
Unfortunately you will need to take it to an authorized service center for repair. Be prepared to spend upwards of $300 for the repair.

Cheers

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.

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.

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 !
