The convergance amp has failed and should be replaced there are two of them and also some resistors in the same circuit may have opened. if you tried making adjustments in the service mode you might have set the data too far out of the tolerances of the amp current draw and it may fail again. unfortunatly there is no way to reset this to factory reset to undo what you have done in the service mode. I hope you didn't write the data that is your only saving grace. the convergance amps are the stk392-560 sony part # 8-749-019-08. if you are not a tech it would be difficult for you to replace these have a tech do it or at least assit you.

Sony kp51hw40 has green shadows and on edges in pictures and blue flickers on and off, tried all adjustments including screen, focus, and menu??? no luck


The CRTs in this model of TV had a problem with internal leakage. The blue was usually the first to show the symptom (flicker). Because all 3 CRTs are connected to the same high voltage source, when 1 acts up, the other 2 suffer as well. You need to replace the Blue CRT. However, this TV has some age on it... 1 tube will lead to 2 tubes, and 2 tubes to 3... They only last about 7 years. If you love the TV, replace all 3 (about $200 each). I recommend replacing the Red and Blue first, adjusting the geometry and convergence to the original Green. Then replace the Green, adjusting the geometry and convergence to the new Blue and Red.

My big screen tv looks 3d and red green blue are off


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
