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.
exact same problem

Hi,

The diagnosis you have made is correct. The Convergence amps are not working up to their optimum power causing the image to come in a concave shape. These amps are necessary for positioning the image in x&y co-ordinates accordingly. If you are not a circuit savvy then, I would recomend you to take it to the technician or a service centre.

Thanks

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.

Sony KP-46WT510 Rear Video Projector Convergence Problem


Subject

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.
