Do not use any solutions. Use a dry, dust free cloth. If there is something on the lens that is sticky, you can use a drop of Alcohol free cleaner and you must put it on the cloth first. Do not let it run.

Message says airfow blocked, turns on for about a minute then shuts off


1. Remove the air intake filters on your DLP projector. As explained by InFocus, a manufacturer of LCD and DLP projectors, each DLP model will house the air filters in a different location. However, for most DLP projector products, the filters are accessible by unclipping a simple plastic latch.

2. Wipe the air filters with a small cloth dipped in rubbing alcohol.

3. Blow compressed air into the unit's vents. This will force some internal dust out of the DLP projector, but you may still need to open up the unit for additional dust removal.

4. Unsnap the main cover from your DLP projector. Because DLP projectors need periodic lamp replacement, the main cover is rarely secured with screws or bolts. However, if the DLP projector's cover does not snap off, then you'll want to inspect the unit for possible screws or an alternate release latch.

5. Reach in and remove visible dust globs with a paper towel. Be careful to avoid touching the lens, as fingerprint smudges can diminish DLP projector image quality. If you accidentally smudge the lens while picking out dust blobs, wipe the lens with a dry, lint-free microfiber cloth.

6. Spray compressed air into your DLP projector to remove any lingering dust particles.

7. Close up the projector and reattach the filters.

Just wanting to know how to remove the front screen to clean the dust of the projectors


You can do that but an easier way is to remove rear cover (set unplugged)and clean the lens with a lens cloth or paper towel with glass cleaner sprayed on it.

It is fairly easy to damage screen when removing it/replacing it.

Let me know what you find.

Mitsubishi wd 62527 has very dark picture changed


Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

How can I remove the back cover on a SAMSUNG HCR5245W, I need access to clean the mirror and projectors. Already removed all screws. The back cover appears to be made of two parts but I cannot split. From...


Hi my name is Roety,
I can help you with your issue ,
Leave the top rear half bolted on.
Remove the rear edge screws to remove the front half, then remove the front lower section by taking out the few rear screws holding it, then there is another piece just below the screen that pulls off revealing the last few screws holding the top front screen section in the front lower edge.  Take the front off, cleaning the mirror and lens will help, but I'll bet the fluid is dirty inside the blue and green tubes, look into the tubes with the TV on to check.
best of luck

Mitsubishi WD-62527 replacement lamp install and brightness low


as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

How to take cover off


First, my disclaimer:

I have a much older projector, but the way they are constructed hasn't changed a lot to my knowledge.

An excess of dust can shorten the life of electronics, it's a given. But the majority of these sets are allowed to collect dust for many years of operation before any problem occurs.
I sense that you may instead be asking about cleaning the lenses and mirror. Actually, the mirror, since it faces somewhat at a downward angle in these sets tends to stay clean. the lenses however, face upwards, and do get quite dusty, causing a blurry picture, with ghostly images on the screen at their worst.
To clean the lenses on most RCA sets I've seen, the screen must be removed. Allow the set to cool and voltages to dissipate for 30 minutes before beginning this process. There should be a removable panel beneath the screen, usually retained by screws on the backside at each end. REmoving the panel will expose the screws that keep the screen in place at the bottom. With the screen removed, the lenses (there are three) will be quite obvious. I clean mine with typical glass cleaner and SOFT paper towels. PAY ATTENTION not to allow any liquid to drip into the projector below or you may disable the projector unit possibly causing damage that must be repaired. If you are successful at the lens cleaning you will have restored the picture quality to like new.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!
