Question about BenQ W500 Projector

1 Answer

I have a BenQ W500 with some dark spots in the image. As far as I can tell, the lenses are clean, and I took out the lamp unit to make sure there was no dust or smudging. How can I get rid of the spots? They're most easily seen when the image is dark, they're relatively small (less than 1% of the image), and they're fairly indistinct.

If you can focus the lens on them, they're on the optics somewhere. if you cannot, you may need to replace the fly-eye (diffuser) lens. they tend to fry due to excessive dust and heat.

My unit seems to work fine, except there is a dark shadow covering the right third of the projected image. Is this a sign that the bulb is going out?


this is the light tunnel needing to be adjusted or replaced because is has collasped due to the heat given off by the lamp during the life of the projector.

There is a large dark spot in the lower center portion of the projection area, I have cleaned the external lense and changed the bulb but the dark image remains.


if the spot is circular, check the lamp itself. if it has a flatter edge, chances are your light tunnel has collapsed and needs replaceing. it's not that old, so dell might repair it. but they might replace the entire optical engine, as they may not sell individual parts.

Lamp burn out 3 time in 16months


clean out your projector. if there is a lot of dust and/or no air flow, the lamp will overheat and die. it needs to cool. use canned air and blow out any and all dust from inside the projector. make sure the fans work. also, don't buy lamps from "bob's lamps". get it from a reputable benq dealer.

the light filter on the blue lcd is fried due to excessive dust and heat. clean it out with canned air and replace the filter. unfortunately, you might have to replace the entire optical engine because benq doesn't sell individual parts for it.

Bluish image appearing on screens


It sounds like the projection lamp is beginning to show its age. How many hours of use does the unit have on the bulb? The bulb are typically rated for about 800-1600 hours of use before they go bad. The bluish image on the screen image is a typical tell-tale sign that the bulb is going to need replacing.

Most of your better projection units will have an internal time counter of the bulb life from the time the unit is first used or when a bulb is replaced. Check to see if your unit has this feature, if so it will show you on the screen display what is the total number of hours on the bulb and the estimated remaining hours of life.

Be aware that the replacement bulbs are NOT cheap and usually will cost you several hundred dollars, I have seen bulbs for professional projection units used for large convention/presentations have bulbs costing as much as $500.00 USD.

One other last thing to check is to clean the lens of the unit both inside and outside. To clean the inside, you will need to remove the bulb (be sure to wear a rubber glove as the oils from your skin will cause the lamp to blow, (causes a hot spot)). Then using a cleaning wipe, just as one used for cleaning microscopes or glasses, wipe the lenses. The discoloration might also being caused by dirt and oils on the lenses.

I hope this shed some light on your church's projection problem.

Dark spot issue.


Its an acrylic condensing lens inside the light engine that has melted/warped. You have to pullout the entire light engine then disassemble the optical light tunnel to get too the lens. Then you need a lens-smith to cut a new lens because Infocus won't stand behind this design flaw. Its really a shame on Infocus!

New lamp but image is dim


This usually means that there is some contamination in the light path. Since many of the mirrors and lenses must be carefully aligned, it is not recommended to have the homeowner dis-assemble +/or clean these. This unit should be sent in for serive, requesting a complete clean and alighment. The unit will be cleaned, any filters changed and the convergence checked.
