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.

Model indicated is a projection set with three picture tubes.

Cleaning may help your problem--two ways to do this-

with set unplugged remove rear cover and clean the three large black lens you cannot miss--if dusty the picture will be dull and darker--should be done once a year.

Peek up inside to the rear and look at the mirror--unless grimy leave it alone.

Other way is to remove entire screen unit which if you have not done that entails some danger of damage to the screeen.

Try cleaning the lens to see if improvement.

The lens is not sold separately, you must replace the whole assembly. This assumes you are talking about the headlight lens.

I bought a 800 to 1200 lens it seems to have a hazy look when I take pictures I have tryed different distances and I use a tri-pod and wired remote any tips

There are several possible reasons for this.
You may be seeing haze. With such a long lens, you're often taking pictures of things very far away. In such cases you're going to get haze (smog, smoke, fog, and other stuff in the air). A UV filter can reduce the effect somewhat. To see if this is the cause, try taking some pictures of something closer (like the opposite end of your living room) and compare.
If the sun or other bright light source is shining onto the front of the lens, that will reduce contrast and produce a hazy look. Use your hand or a piece of black cardboard or something similar to shade the lens (being careful not to get the object into the picture). Take pictures away from the sun and toward it (not directly toward it, just in its general direction) and compare.
The lens may be dirty. Clean the front and back with lens tissue or a microfiber cloth. Don't take the lens apart to clean its innards unless you have a lens collimator and other gear needed to put it back together properly.
Even with a tripod and remote, you may be getting some camera shake. If your camera has a mirror lockup or exposure delay mode, use it to damp out the mirror slap. If your camera doesn't offer either of these, try using the self-timer.
Also, make sure your tripod is sturdy enough. It's a heavy lens, and even if your tripod holds it, it may not be holding it very steady. Try putting your camera on a tabletop and shoot something at the other end of the room and compare the results.

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.

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
