Solution:
You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.

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. 

>>>Solution<<<< 

You need to replace the convergence chips and convergence resistors. 

Check the site www.TvRepairKits.com.
They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

SOURCE: Sony KP-41T15 Color problem

Does this happen when you play a dvd? if so your RED, GRENN, and BLUE lenses in the tv may be out of alingment. First try pulling the power on the tv (make sure the tv is turned off first) wait about 2 min. then plug it back in. If this stil continues, then what i said earlier may be the case and sorry to say unless you have a warranty you will be better off to buy a new tv. Now days it costs more to repair a tv than to buy a new one. And it could very well be the receiver

you will need to replace the two STK392-560 ICs and also check the 4.7 ohm 1/2 watt resistors and the six 3.5 amp pico fuses.

How do i fix red and green color alignment on a sony kp-43770 tv


Model number does not sound quite correct but if a convergence problem both chips the set uses will have to be replaced and the set adjusted with the Sony remote.

Confirm actual model number and Google it with "parts" to see what it uses. Most convergence chips will have the actual STK number right on the front of them and almost all Sony sets use two chips.

The screen looks as if it is 3D. The colors are all offset.


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 photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

My sony KP3T90 has showing 2 colors on the screen,red & green


If after trying the auto focus correction you still get the colors out of alignment you will need to have the tv checked for defective convergence power amplifiers, these make the color correction and are always hard driven so they need to be cooled down by way of heavy heat dissipators. repair of the convergence board often take the two amps plus some pico fuses and depending on the experience of the tech it might be done at the house.
