KP-51HW40 Convergence Problem

Multiple images of red, green and blue and bowed in the center from top to bottom. Do I need convergence ICs and resistors? If so, can I do it or do I need to pull the board and have you do it?

    I received the parts but need instructions. I thought they would come with the parts. Do you have any?

    I have the same symptoms: Multiple images of red, green and blue and bowed in the center from top to bottom. The bowing gets smaller as the unit warms up.



    I have purchased the recommended parts or the manual yet. Usually, I purchase the manual first, troubleshoot, then get the parts to fix. Is this issue so cut and dry that replacing the two convergence ICs and the pico fuses is the only solution to this problem?

Actually your model should only need two STK392-560 Convergence ICs and six 3.5 amp pico fuses. You can get the replacement ICs and pico fuses at the following link with free installation instructions. Heres the link.

I have Sony KP-46WT500 Projection TV. For some time it appears convergence went bad. I see multiple images, especially at edges and corners. As many as 3 images Red, Blue and Green. I am an Electronics...


Hi,
It would be great to assist you in Sony convergence issue.
As you said, for some time TV shows bad convergence in picture that shows its matter of lose/ dry solder joints in D board, specially on convergence out ICs pins that need to be re-solder.
There are 2 big black ICs mounted on aluminum heat sink on D Board of TV, below image shows D Board location in TV.
Resolder pins of these 2 ICs and also check any other dry/ cold solder joints in circuit board. I do not think of IC replacement as problem occurs some time.
Let me know if you have additional question.
Thanks.

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.

Distorted image and color


sounds like the convergence ICs have failed. Will the red and blue move in all 4 directions when you try to adjust the convergence? If not the convergence ICs are bad replace both of them also check the resistors that power the ICs as they may be open as well.
