Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television

1 Answer

Convergence issue My Sony KP-46WT500 (5 1/2 yrs old) went from a perfect picture to moderate separation of colors. I'm seeing a slight bend in color in the upper left hand corner of the screen. The Flash Focus doesn't remedy the picture. Any suggestions?

You need to replace both STK392-560 convergence ICs and some of the 4.7 ohm 1/2watt resistors. You can get replacement ICs and resistors at the following link with free instalation instructions.

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.

Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.
