Sony KP-46WT510 Rear Video Projector Convergence Problem

I have had this television for almost 5 years; the manufactured date was July 2003. One day, the image on the television was all screwed up:

  • There is a concave image(middle part of the picture bending in and the outer ends bending out)
  • The red-blue-green colors were separated so it looked like 3 images at once
It's all blurry with color messes everywhere. There are red and green lines at the ends. It also has the same problem with my DVD/VCR.
Convergence menu and flash-focus doesn't work - otherwise the t.v works perfectly fine.
From all the other questions, I think the problem is something about replacing convergence amps, whatever that is. But I'm not circuitry-savvy so I don't know what in the world I have to do to fix it. What items do I need, where can I get it, how much will it cost, how will I fix it and is it advisable for someone to look at it or will I be able to do it myself? (I'm handy at fixing things) Is there anyone willing to share their time? Thanks a bunch.

    Hey - I have exact same problem...picture looks concave and there are three distinct images in red, green & blue. TV is less than 5 years old and other than the 3-D looking picture, everything else works fine. Haven't gotten a quote on getting it fixed yet.

    I turned the tv on and the writing was in yellow, red and blue. The picture looks curved inward. The images in different colors are almost on top of each other. What is causing this? It worked fine a couple of hours before. ow do I get it fixed?

    Thank you.

    Hi fellas,



    I seem to have the same problem with my HDTV; I've bought it new, and have owned it for about the same amount of time as the other people reporting this issue. What do you recommand, do you have the parts/part numbers or know how to order it and how much it might cost to repair it.



    Please advise,



    Best Regards,

    Same problem and owned for 4 to 5 years.  Anyone actually got it fixed or should we just bite the bullet and buy a new set?  Scanning the web, it seems this could be a $1,000 job.

  • colombicho Dec 11, 2008

    convergence can not be auto or manual adjusted. the video is red and out of focus

  • bb_banking Dec 19, 2008

    I too have the problem. My set is about 4 years old and was informed that the problem is a convergence circuit DNR needs replaced. Live in ohio and was quoted $335-$375 to fix. Wouldn't you know that its the right in the middle of my price point to purchase another. Rest assured , Sony will not in my lifetime be another tv product that I purchase. - Jim in OHIO

Video bowed in, convergence out, PS5001

Symptoms / Customer Description
Video bowed in and convergence is out.
[Primary Symptom Code: 1436 ]

Solution

Found PS5001 on G board was open.

HQ Comments: Could be cold solder joint on one of the STK IC's on the D Board. They run hot and the solder connection might have broken down causing intermittent condition which could have opened the fuse on the
-22v line.

My sony tv model # KP-46WT510 the picture bows to the middle i tried fixing the convergence and it does nothing what else should i try


If the convergence feature did not fix the issue then you will need to install a convergence repair kit. Your model uses the Sony type 1 convergence repair kit which is available from www.tvrepairworld.com and includes the parts and the CD with instructions.

I have a Rear Video Projector model # KP-46WT510 and it started acting up. It is a double picture when we try to watch TV. Can this be easily fixed?


Unfortunately it is a job that will require an experienced TV technician,
You have 2 large 18 pin ICs called convergence amplifiers who's job is to insure beam alignment of the three picture tubes in your TV set (Red, Green & Blue). One of the 2 chips have shorted and more than likely cause damage to the 2nd one as well. This involves removing the board where the ICs are mounted then rmoving the ICs by a process called desoldering & resoldering during the replacement process. They are not a plug in Ics.
Hope this helps.
