Sony KP-57WS510 Convergence issue?

I have a Sony KP-57WS510. It has worked perfectly for 4 years. Just yesterday the image on the TV had a concave top & bottom, but is straight on the left and right sides. You can see the red, blue and green images separate on the top and bottom of the image. The center of the image is fine, and in focus. Any idea what the problem might be?

There should not be a need to replace the chip if the fuse below the convergence chip is blown. Check to see if there is a short in the convergence output (after the fuse). If nothing is seen then replace the fuse and see if it works.

Tripe image, blue, red and green color on image, not focus


you will need to replace the two STK392-560 ICs and also check the 4.7 ohm 1/2 watt resistors and the six 3.5 amp pico fuses.

Your set uses two STK392-560 convergence ICs they are attached to a large heat sink on the D board. You can save your self about 400 for a twenty minute repair by getting new ICs at the following link as trhey provide free instalation instructions with pics so you can do the job yourself. It only requires basic soldering skills I would order about six 4.7ohm 1/2 watt resistors as well just in case you need them asusually sonys' will burn one or two of the 4.7ohm convergence resistors when the ICs fail. Heres the link
