If you have experience soldering on solid state printed circuit boards and know how to take out the old IC, install thermal paste, resolder in a new IC and re-convergenge the TV set, yes it can be done by the owner. If you are not experienced soldering, my best advice would be to call in a tech to assist you in this repair. Good luck

Hi,
This is symptom of convergence output chips failure in rear projection tv, replace convergence ouput ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can solder parts in circuit board then check 2 big black ICs mounted with aluminum heat sink on D board of tv, replace them with same numbers and if you feel uncomfortable working with tv circuit boards, local tech will help you.
Thanks.

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.
