You can go to menu, convergence adjustment. If you can not move the red or Blue hair cross. It is surely your TV Convergence chip(s) bad.

Try using the MENU button on your remote control to go into the TV picture settings menu. Change the mode to NATURAL, You can also try to manually adjust the color in the COLOR SETTINGS mode.

If that doesn't work, check out the handy troubleshooting chart in TV color problems and see if another solution will work. I hope this helps!

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.

Hi,I have sony projection tv KP-57WS510 every subject apears threeple with colorful reflection.What to do? Thanks,Kris


You will have to install a convergence repair kit which will consist of both convergence ICs and the 8 associated pico fuses and the 4.7 ohm resistors will also need to be checked. Your model uses the Sony type 1 convergence kit. If you want to know where you get one they are available from www.tvrepairworld.com they do include the parts and the CD with repair instructions.

Hello i have a sony KP-46WT510 model 45" TV, and


Below are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

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 Projection TV sets and a fairly simple DIY fix.

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 - 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.

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 solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.

This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from TvRepairKits.com

Their kits include a step by step instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection 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 video.

Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

Set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

Color issues


This is a convergence problem that can be as simple as poor solder connections at the convergence ICs to defective ICs. Can you solder? If so, let me know and I'll provide additional instructions.
