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?

    I also have the KP-46WT510 46 inch rear projection and mine started doing the very same thing you described. Less than a week ago, it went to the 'blurry screen' with Red/Green/Blue accents, turned it off, waited a bit, turned it back on and it worked for a couple hours and then went 'blurry' again and has stayed that way. Has anyone else experienced this? If so, what is the fix and what was the cost?

    Sony KP-46WT510 is less than four years old. The picture shows double images. The color red is especially falling in the lower right-hand corner. Sony gave us phone numbers to repair shops that will not travel to us. Estimates between $400-$800, with no guarantee after a year of repair of a proposed convergence problem. I don't want to spend that much more money and have it happen again.



    Sony should be ashamed to place their name on this television. What can I do with the monster?

    I have the Sony KP-46WT510 (4-1/2 years old) with the same convergence problem. A nicely curved picture with green and red highlights everywhere. The Flash Focus shows the three colors never converging. I would like to replace the two STK ICs on the D board and think that I have located them as being on the two large heat sinks on the D board at the rear of the TV. Is that correct?

    I am having the same problem, curved picture almost looks like a bow tie.

    I've seen comments about heat sink and IC's..what are they are where are they located?

    Thanks

Sony 51" Rear Projection TV is blurry with colored ghost images


Thats caused by a convergence failure. The Sony type 1 convergence repair kit from www.tvrepairworld.com will usually correct that issue the kit contains the components and the CD with repair instructions so you can repair yourself.

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.

CONVERGENCE IC ADJUSTMENT


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 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.
