    Same problem. Purchased Sony KP-46WT510 in Feb 04. Problem occurred on 5/29/08. Picture looks curved. Upper left corner and lower corners appear reddish/pink. Green lines /Ghosting appears on screen. Double lettering. Is this something that we can fix ourselves? We have done the Flash Focus and manual Convergence adjusting with no change in picture. Thanks,

    Hello,



    I also have a KP-46WT510 (Sony) where the edges are curved especially very noticable when there are words on the screen. And the colors are out of whack with orange and green, etc.



    Please let me know if this is something that I can fix. Also, if a professional is needed, how much should this repair cost?


    Thanks for your help!!

    Our extended warranty ran out in April on our KP46WT510 Sony rear projection TV. This past week we turned on the TV and found that our picture was concaved, with color separation at the top left and bottom right of the picture. We had someone from QService come out and told us that our D Board was out and that we could have it sent to Sony for refurbish for $460 and the TV would be out for 3 weeks while this was being repaired. I wonder if Sony has thought of building a surplus of these, since it seems that this is happening to many of these TVs that are 3 to 4 years old. There has been some talk in these forums about replacing something called an "ic". Is this what Sony would do to refurbish the unit?

    Same problem. Purchased Sony KP-46WT510 in Feb 04. Problem occurred in September, 2008. Picture looks curved. Upper left corner and lower corners have color separation. The letters are doubled. Flash Focus and manual Convergence adjusting do not work.

    same problem....in a short time.... If this is a common problem with SONY, I wonder if they have built a fix-it your own type of kit....

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 www.TvRepairKits.com. 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.

Three curved lines have appeared approx. 6" up from the bottom of the screen. Is this a simple fix .... maybe as simple as replacing a bulb?


Are you saying that the whole picture is gone and all you see on the screen are 3 curved lines near the bottom, or is the picture there but 3 curved lines are over the picture, or is the picture there but the bottom of the picture has curved upeards?
