Question about BenQ PB6100 Multimedia Projector

Cleaning dust and dirt from the lens (inside)

How do you safely clean the optics of a 6100. I can see dust particles on the inside of the lens (looking through the lens at an angle). I cleaned the lens on the outside with a camera lens cloth but don't know how to approach cleaning the lens on the inside. Thanks!

Hi Nutty Prof

You will have to open up the unit by unscrewing the screws at the bottom and taking off the top cover of your PB6100.

Right behind the lens is the Lightengine ( where the dust collects )

Take off the cover of the Lightengine by unscrewing the two screws at the top of it . Then blow out the inside of the light engine with Air in a can ( available from most good PC shops )
and then reassemble.

If the dust particles still show after this ( which I doubt it will ) then you will have to take it to a Service Centre to get cleaned out as you will not be able to reassemble the lens once taken apart - it is a HUGE job !

Thanks for using Fixya and Good Luck !

HOW DO YOU CLEAN THE INSIDE LENS?


You probably don't need to. I know you may see what looks like a lot of dust, but unless it's completely covered, that dust on the lens has very little effect on your projected picture. If it is really bad, you can try to open it up and clean the lens with a lint-free lens cleaning tissue (NOT FACIAL TISSUE) and a couple of drops of distilled water (or lens cleaning liquid). But you best bet, if it's really dirty is to take it to a service facility.

I replaced the lamp in my projector because the image was dull. The new lamp however has made very little difference. The projector is 3+ years old. Could the problem be dust and if so what is the best way...


check manual or call Sony

lots of optics on projectors have a coating on them that will be ruined if you use any type of cleaners on them

to be safe you could just try to blow dust off or wipe gently with a lens cleaning cloth

good luck!!

I have little spots all over the screen display, i believe to be caused by dust in the lens assembly. could that be the problem? i see a lot of dust behind the glass... how do i clean it?


Hi,

If there is dirt or other deposits on the LCD panels they are usually most visible at the extremes of focus. They will be blobby. You may also be seeing dead pixels which are clearly visible when in focus.The lens assembly itself will be sealed and is unlikely to be the problem, don't worry about flecks of dust in the lens area. You can clean the external lens with a soft cloth, much like a camera lens.

Projector internal optics are non-user servicable. If you can't live with the spots it will need to go to an approved center for cleaning / or repair. You should be able to find out where via this page

There is dust inside the lens. how do I clean the dust from inside the lens?


Your projector needs little maintenance. The only thing you need to do on a regular basis is

to keep the lens clean.

Never remove any parts of the projector except the lamp. Contact your dealer if other parts

need replacing.


Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

• Use a canister of compressed air to remove dust.

• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner

and gently wipe the lens surface.

Never rub the lens with abrasive materials.

Unplug you projector and allow the bulb to cool. Open the area where the projector bulb is located. Check the projector lens for any damage and clean it from dirt's and dust. Same as with the bulb.

Im getting spots projecting on image


Check for dust on the lens. There may also be dust inside the projector on the mirrors, lenses, or LCD. If cleaning the lens on the outside doesn't resolve your problem, I would contact a professional to get the insides cleaned out.

Good Luck!

Hi there my benq dlp projector is showing white spots on the screen when the screen is black can you help me?


This is caused by dust on the lens assembly. If you can remove the lens, clean the surfaces with a lens cloth. That should resolve the problem. It is possible that the there is dust in the optical pathway inside the unit as well. If the cleaning of the lens does not resolve the problem, the unit should be brought in for a professional cleaning. It is not suggested that anyone open up these units as there are fine adjustments that can be changed internally easily that could result in convergence problems.

DV10 optoma movie time is suddenly not recognizing DVD disks. It has been working fine for nearly two years. The projector works fine when connected to the TV box. The disk player spins but will not read...


there are dvd cleaning disks that work ok. you can get them at best buy or radio shack. they'll just lightly brush the dust off of the lens on the optical pickup. if the unit is is humid conditions, you'll need to use a lint free microfiber lens cloth and gently brush the dirt off of the lens. if there is stuff stuck to it, you'll need denatured alcohol with a scratch free fiber swab to wash off the lens (don't use a lot of alcohol). blow it dry and test it out.
