Rainbows across screen

I have a 58" wide screen projection tv. Last year we had a tech. come out because we had a rainbow going across the screen. He did a minor adjustment and fixed the problem. We have the rainbow again and the screen goes solid light green where you can't see anything. Can't I replace the part with your guidance?

    The speaker is four feet away and the rainbow lines are still there. After some time the screen goes light green. Last year the technician took the front cover of the tv off and adjusted something. He also told me the replacement part would cost around 75.00. This is a projection tv.

IF this is a projection tv of tube nature, you need the projection tubes degaussed. IF it is solid state, you have circuit board problems and that can get expensive...if not impossible when compared to the price of a new TV. BE very carefull of speaker placement near these tube if it is a projection tube type...get the speakers away from the sides of the tv, Turn it on and off several times. (it degausses itself everytime it is turned on)..and see if you see a lessening of the effect...if you do, then with time, this will go away.

Hope this Helped. -CA

I have a narrow green band across the top of the screen similar to a rainbow -also Ex: most of what appears on the screen is double vision. thankyou.karen t.v. is approximately 8 years old


Your TV needs the convergence ICs replaced .
Not something you can do, techs usually charge about $300-$400 to replace them in your house.
I may be worth fixing if you can find a reliable tech in your area.
best of luck

There are flickering, rainbow-like color bands running across the screen, especially in the component inputs, not so much using the HDMI input, but still there.


Hi,if your tv is and Lcd rear projection it will be the light engine that needs replacement.Because lcd technology uses 3 chips green,red and blue that create the image and colors.When they start to fail you will get what you are getting color discoloration and rainbows.If your tv is DLp it will be the dmd chips which basically its like the lcd chips but instead of 3 chips its only one that creates the image.Hope this works God bless you!

I have a 3 year old mitsubishi wd-52526 lcd projector tv that is starting to have some focus/image alignment issues - in general picture is a little out of focus and there are rainbows around things at the...


the differnt guns are out of alignment. Your tv has 3 lcd screens, a red, green and blue one what overlay to form the image. Sometimes they move slightly for what ever reason and that causes the rainbow and out of focus picture. Its something that a trained pro should do but is a cheap fix and won't set you back too much

Sony KP-57WS510 rainbows and arches


no the shape doesnt matter as long as the STK numbers are the same. I would make sure that the replacements are origional sanyo ICs as often the cheaper versions do not last very long.
