Question about Sony Grand WEGA KF42WE610 42" Rear Projection HDTV-Ready Television

Open Question

Sony 42 inch LCD projection TV

I have a blue and yellow picture. When I go into the color slides, the green hue will not slide. But when I run a DVD movie through the TV, the color is fine. It seems to be just the adjustment slide for the green hue. It isn't filled in solid like the other slide controls.

SOURCE: Sony KP-51WS500 Rear Projection TV colors are distorted.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

You can write or call Sony. We had a little battle with this about a year or so ago and it took a little bit of on pour part to get them to help out but in the end they fixed it labor and all. Around a grand to fix. Good luck.
Go to that website has a lot of information that might be very helpful.

most likely, buy you a lamp and install it yourself, the owners manual tells you how to do this.

SOURCE: projection sony tv is yellow

Most likely it is the Optical Block. It has been a issue for most of the Sony LCD Rear Projections manufactured over the last 6 plus years. Your Model may still Qualify as a factory recall. What you need to do is to get in touch with Sony's Customer Service at 1800-222-SONY and see if it does Qualify.
If not, it is a expensive repair costing 1200.00 to a 1500.00.
I hope it still does Qualify for a recall,

The problem is the optical block and nothing else but. Contact the dealer from which you purchased the set to see if you qualify for Sony's extended warranty on this very, very expensive part, which may be covered by a class action lawsuit Check here The lawsuit covers all the KDS models. It seems that Sony continued making these rear projections even though it knew the optical block failed prematurely. When you get it fixed, go to setup and make sure the cooling fan is on HIGH and power saving is ON. Both of those features will extend your TV's life, including the optical block and the projection lamp. Further, bring a portable compressed air tank to the TV and, with a narrow nozzle, empty it into every opening in the set's back. At least once per month, check for dust settling on the rear of the stand behind the TV -- when it gets thick, get the air tank.

Both the picture and sound work when the TV is turned on, yet the picture is distorted like a double picture and has a yellow hue to it.

Sounds like you have a convergence problem. If you go into the setup menu of your TV, there should be some settings to adjust the red, green and blue hues and re-position them so each color matches up. If this does not work or if you don't have a menu, your TV *might* have a circuit board with several plastic screws on it. These adjust the picture and it's a very tedious task to re-align each hue correctly.

My projection TV is an older model from 1995, which is probably why it has this circuit board in place of a convergence menu built into the TV.

If adjusting the convergence still doesn't work, you might need to purchase a new convergence chip.

Sony 60" HDTV Plasma WEGA....Picture Problem

My guess is that you're not missing the color it just appears muted... That problem is a common one in both the 50 and 60 inch models. And if you change video mode with nothing hooked up you'll see a faint color where none should be...
That's simply dust in the optical block on one of either the red, blue or green lcd panel. Wipe it down with a non-linting cloth and a "light" amount of windex and you're back in business...
But check it out by switchin through the video modes with nothing hooked up.. The faint color you see if the lcd panel that's having the most problem and the one that's muting your green.

Dont know what color to stick where

X-box can be hooked up to component video. This is for better picture quality. Not all tvs have this option. Most newer tvs do. It uses green, red, blue. Those will give you the video. Then a red and a white give you the audio. Just match up the colors.

Check you HD inputs or source. Sounds like the red stream is missing; maybe a loose cable.

Color convergance

The green hue (I had it too) is a result of the optical block failing.
