Sony 65 Inch Projection TV Color Red Green Separation

Left half of the TV screen (facing the TV) shows green and red colors separated; in other words I see two pictures - one in red and the other greenish. The right half of the screen shows normal colors. Is there any setting that I can adjust or do I have to pay Sony? For sure this is the last Sony product I will ever buy.

Re: Sony 65 Inch Projection TV Color Red Green Separation

Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.

Re: Toshiba 65 in Cinema Series - 12 years old. Color Separation. Green bow at top center of screen, red and blue double images tilting upwards toward sides. Sometimes clears unassisted after set has...

projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.



Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

When the display is dark i get red and green arcs on the screen


Color arching is an easy fix. You need a screw driver and some patience removing the front panel. You will be looking for a box with 3 screws on it. This is the color gun. THe scews are Red, Green and Blue color only, however, they usually don't indicate the color on them. Turn the screw (Slighlty) till the arching is no longer there. You have to do this with the tv on.. LOL

Double Image Red and Green

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 email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

My T.V. has a funny color .. more of double viewing with purple and green what can I do to fix this?

Your set has a problem with its convergence circuitry. In many cases this can be simply failure of solder connections to the output integrated circuits due to the heat they generate, and resoldering them fixes the trouble. This is a repair you might be able to try for yourself if you have experience with electronic soldering. Or there might be component failure which would require the equipment to isolate and replace the bad parts, which is a repair level best left to professionals. In some cases where the set has digital convergence, the failure might be in the computer control portion. This means the repair might range from only a very few dollars in parts to quite a lot of dollars, plus whatever labor rate the servicer charges. If you aren't looking for an excuse to replace the set, getting an estimate on a professional repair would be the best suggestion.

Degaussing is deliberately applying a magnetic field to the face of a picture tube. This is done to neutralize the effect of other magnetic fields that can cause color distortion. Degaussing isn't done in projection sets because they have separate tubes for each color.

Convergence not lining up

Sounds like the green is out of focus. If the focus control for the green does not control it enough to make the width the same as the red, then, the lens on top of the green can be adjusted to focus that tube. On the lens, there is a wing nut on a screw to loosen it and move the lens left or right a bit to help with the focus. Hope this helps.
