Question about Sony KP-46WT510 46" Rear Projection HDTV
I got this TV from a family member the other day. I like it except for the fact that lighter colored images seem to wash out, or dull the other colors in the picture. It is particularly annoying during hockey games.
I've used the various adjustments in the menu and can't seem to get it under control.
Your TV most likely has one of two possible problems.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
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 Sony KP-46WT510 46 Some colors appear faded or was - 2c07611.pngctions your convergence chips are bad and should be replaced. This is a common problem.
