Need to Clean The lense


If this is a projection TV (DLP or LCD), dust could be on the lens or the mirror assembly. Moving a set can dislodge dust and dirt that's accumulated inside and deposit it onto the lense or mirror. A worst-case scenario would be dust on the LCD chips. Unless you're experienced and/or comfortable opening up the set, I'd recommend contacting a local TV serviceman.

Remove tv screen from hitachi projection tv


The entire screen unit can be removed but first remove rear cover and look at the lens--clean with a lens cloth etc----peek up inside and look at the mirror--if not dirty or smudged just clean the lens.

removing the screen with its frame can be tricky--easy to damage the screens etc. Removal usually requires front speaker grill to be removed first---most just pull off but a few are secured from rear by some screws.

With it off look to see if at bottom of screen there are a row of screws--if the entire front unit can be removed it will pull out at bottom and be snapped in place.

A better suggestion is look at rear of set above back cover--if the upper part is plastic--it with the back removed can also be removed--careful as mirror is bolted into it---that way you can clean the mirror and get at the lens for the tubes without trying to remove screen unit--some of the smaller sets this is the ONLY way to get at the mirror.

Yes a number of screws but if plastic upper rear comes out with mirror much easier and safer way.

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.

The tv looks too dim. you have to stand right in front of it to see the picture but it still looks dim.


Other than a circuit problem it may be dirt or dust on the lens. The model indicated has 3 picture tubes.

If you unplug set and remove back cover you should be able to see and reach the large black lens dead center and above the circuit boards. If the lens are very dirty the picture will be dark and dull looking.

There is also at inside top back of set a mirror--if it is dusty or has grime on it, same thing--not as easy to get at but with back off you can use a small mirror to examine it.

Clean the lens with a lens cloth or a paper towel with glass cleaner sprayed on the towel.

With back off, 2 minute job and if picture now much brighter, you are in business. Lens, depending on how much dust etc in your area should be cleaned one time a year or more-----do it yourself job and easy.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

Need to clean the bulb to make picture clearer is this possible?


Because of age of use, dust covers the PRT lens (Red, Green and Blue) and Mirror as well. You can clean them with a soft cloth, with care. It is easier if you can remove the Screen (front side) but it is kind of complicated. The easier option in most of the Rear Projection TVs is to remove the lower cover and check if you have access to Lens and Mirror. Avoid excessive pressure in lens and specially with the mirror while cleaning is made. This process can make the picture clearer, specially if dust is excessive.

Picture fuzzy on dark scenes


Well I finally had the TV picked up by a Toshiba recommended repair place and they are saying that it is a bad Optical Block, also known as the Light Engine. Total for pick up, parts and repairs is $827.00. This seems ridiculous to me when brand new TVs are so much cheaper now. I don't think I will pay that much to have this one fixed.

Mirror


There is black insulating foam that surrounds the projector and it may be displaced to one side.This leaves about an 1 inch opening around the projector lens and that could be the source of the problem,dust being blown into the compartment with the mirrors.
Cleaned the mirrors really well and used double stick tape to reattach the foam to the plastic frame and this will closed off the opening that maybe letting the dust into the mirrored area of the TV.
