Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Dull colors I have a Sony 57 inch widescreen Projection TV. Model number is KP-57HW40. The set is maybe 5 years old. About 4 months ago I noticed that the colors were no longer "vivid", instead they were dull. I didnt adjust anything. It just happened. I don't want to spend too much money in order to get it repaired since the price of flat screen TV's is low, yet I'm willing to spend a couple hundred bucks to get it working the way it used to. I imagine that if i get someone over the house to repair it they'll want 100 bucks before they even walk in the door. I do have some technical competence. Is this something that I should attempt to repair myself provided i have the right servicce manual?

    WOW!! Thanks alot. When I removed the back cover and inspected the lenses i knew right then and there your suggestion was spot on. The lenses were covered with dust, and I don't mean just a little bit either. I used the right tools to do the job and in 5 minutes I had my old picture back. Again, thank you!!!

Remove the back panel and the inside panel which slides out on a track so you can get to the 3 crt lenses. Clean the dust off of the lenses with a soft lint free cloth, such as a camera lens cloth. You should be able to find one at a camera store or Radio Shack. Clean with a safe glass cleaner NOT WINDEX. Be sure not to scratch the lenses.

I have a Sony Color Rear Video Projector Model KP-57HW40. Its blue color is not working anymore and noticed some burn smell by the set which controls such blue color.


It may be the CRT drive board which is attached to the bottom of the Blue CRT. I would check that Board for signs of being burnt it may need to be replaced.

Picture turns green ,usually within 10 minutes of turning it on.It will sometimes go back to normal color but generally returns to green.This happened when the set was much newer and Sony replaced all...


Green Tube maybe trying to short out or you can try adjusting screen drive to the Green Tube by turning control down a notch, Sony had a bad run on these with alot of Bad Tubes.
