Dust Inside lens

I see dust inside the lens of the projector. This seems to cause a blueish tinge on the hole screen which is more concentrated in some areas. This is inside the lens so not cleanable other than taking the lens assembly apart - is that even possible? Is this problem reparable?

SOURCE: blue spots on screen

Obviously this is not the first lamp you have replaced in you projector. These are great projectors however, the LCD panels expire quite quickly. You will find that the spots are related to the LCD panels needing to be replaced. This is not an inexpensive maintainence solution as the panels cost about $1500 each.

Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

my dear friend, it appears that you must have opened the 3 lcd screws that are not supposed to be touched, if so then just forget reassembling the same as the convergence would be lost & cannot be manually done
another thing are the polarisers.if excessive dust had accumulated & if you used wrong technique in cleaning then the coating would have come off & you have lost everything , just change the entire lcd block.this costs a bomb.beter to buy a new projector

Hi,

Firstly, try the focus function on the lens...

If spots are still present, then there is either:

a) foreign particles inside the lens
b) the LCD panel/s (guessing it's LCD, as you did not specify) have dead pixels
c) the colour filters are damaged


Cheers,

Projector is on comming pink screen


What type of connection do you have? If VGA, make sure it's plugged in correctly. Check for bent pins. The cable may also have a broken wire inside. Also, there maybe dust inside the lens housing or an incorrectly seated ribbon cable inside the projector. Would be good to know make and model of the projector.

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.

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.

How do you clean inside the lens


canned air. if you take the lens assembly apart to try and clean it any other way, there's a slim chance you'll get it back together properly. plus, they thread lock it. it's usually air-tight, but if it isn't, used the canned air to blow the dust out. chances are, the dust is inside the projector itself and on the back side of the lens assembly.

The left side of the screen is blueish?


The blue or yellow haze problem in this projector is because of two factors. 1) Dust buildup inside the optics and 2) Fading colour filters used in the internal optical process.

Inside the projector the white light from the lamp is split into three distinct colours of red, green and blue. Each colour illuminates their own monochrome LCD. Those LCDs are mounted on a prism that combines the separate images and displays the result you see via the lens.

The optical process to split the light up inside the projector is fairly complex and involves many light filters and mirrors to direct the light to the appropriate lcds. Those filters and lenses accumulate dust and also fade over time due to heat and other environmental factors.

I know that sharp sells replacement filters at $100 a piece. I do not know if Hitachi sells replacements.

To remove the dust and change filters you have to take apart the projector in a fairly complex way. I do not suggest that the average user do this. Good luck!
