Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Picture on sony proj. kp57wv600 has been looking "hazy" lately.

Is it possible to clean a) lens or b) mirrors. I remember when they sold
me the set - that a service call would include cleaning of the mirrors.
Never had a service call but remembered the statement.

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.

The picture seems to be getting less and less bright. can I clean the mirror on the inside of the cabinet or something

the mirror is usually not the problem----this set has 3 lens that if dirty will make the picture darker and somewhat dull. most of these sets you can unplug and remove the back cover and see the 3 black lens----clean them with a lens cloth or with a paper towel(spray on the towel first with glass cleaner)

Mitsu #WD52327 DLP replaced bulb but hazy picture

Did you clean the small mirror. Dust will cover this mirror and give you a very hay picture. This is easy job and takes 15 minutes at the most. Someone posted detailed destructions on how to do this already if you look for it under WD52525 hazy picture.

Sony kf-60we610 washed picture

if everything including sony menu is unclear, yeah cleaning may help. dirt can get inside the engine too. look at a white screen, this is your answer (or a black in some cases). any dirt on mirror or lense will be uncolored distortions. colored distortions are inside the light engine.

Enhancing picture quality

You might try taking the screen panel off, taking care to look for attached connectors. Make sure unit is unplugged before attempting this. Use a good glass cleaner to clean off all three projection lens assemblies. Do not attempt to adjust these lens, just clean them. Also clean the reflecting mirror at rear and inside surface of the screen. This should improve brightness and focus if they were soiled with dust
