Red line convergence problem on KP-57WS510

Today when I turned on my TV, I now have red ghost images and red lines that streak across the screen. This is true no matter what the source of the signal. At the bottom of the screen any lettering that scrolls across the screen actually shows up also as red letters which curve up instead of travel side to side. I assume I need a service call. What's wrong? I have heard replacing 2 convergence ICs will solve the problem. Is it worth to try?

Ghosting and bad color, sound is fine.


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...
