Sony Projection TV KP-46WT500 Convergence Problem and Sparking

My Sony projection TV KP-46WT500 has a convergence problem.
After I install two new IC STK392-560 and changed one of my yellow Pico Fuse(5amp) on the G-Board, I plugged back all the plugs and turned the TV on and I saw sparks.I can still see the TV, but the convergence problem still continues. I turned off the TV and turned it back on and the sparks were on a different location. I need help. What is the problem with the sparks and the convergence?

Extra Info:
I bought my pico fuse on the internet and when I recieved it, it was green. Is there a difference between a Green and a Yellow Pico Fuse?

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.

Sony kp 46wt500 has 3d screen what might the problem be?


If convergence out ICs got defective then TV shows that kind of picture.
Replace IC8001 and IC8002 on D Board, both big black ICs are mounted on aluminum heat sink and number STK392-560 would be written on it.
Required ICs are available in Part Store, click that link to see an image of IC and price info.
If you are not comfortable with soldering parts in circuit board, call local tv tech to replace it.
Thanks.
