Question about Sony KP-46WT510 46" Rear Projection HDTV

1 Answer

Blurry Curved Picture

My Sony KP-46WT510 tv picture is blurred with red green and blue outlines around everything. I turned it off for a while, then turned it back on again and it went away. Now the problem is back and the picture is slightly curved too. Turning the tv off and on again is no longer working. There seems to be a short or malfunction but where?

The middle of the picture is fine but the sides of the picture look like they are double with a red outline

The TV has a convergence problem, the IC’s for that circuit will need to be replaced. The cost for this repair runs around $450.00 or more.

My KP-46WT510 picture is out of alignment. There is no conversion of the red, blue and green pictures on the screen. They're off by about an inch of each other.
Some tech told me that it was the power control that was bad. I can see the picture, just very blurred.
Is he right? The tv was not move at all before this started happening.

Picture looks curved (concave curve) on my sony KP-46WT510

You may have a convergence problem. Here are some of the most common symptoms and example photos.

  • 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.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Our picture is green

This is not a user serviceable problem. Apparently the red and blue screen colour tubes/guns are inactive. Possible open green screen control. Also, if CRT type, the tube may be failing
