Color distortion for Sony KPR-46cx35

After several hours of use, a red horizontal line appears on the screen. The top half is green and the bottom half has normal color. This problem is intermittent.

    The TV is maybe 15-20 years old and the problem appeared recently. Wouldn't a cold solder joint show up earlier?

I have a Sony KDP-57WS550 TV that has a convergence problem. Based on the symptoms, I'm not sure whether to indict the convergence ICs. In the convergence mode, I can move the red (and blue) crosses,...


With your TV in setup Use a small magnet to "move" the non converged Red, Blue, or, Green color lines "crosses" (each CRT will need to be adjusted in turn) by moving the magnet close to the offending Red, Blue or,Green color CRT yoke or, tube while observing the movement of the CRT color line "cross" in a mirror ( try several places near the tube and, several strengths of magnets:) a refrigerator sheet magnet works well (you can cut these with a scissors to make a better fit or, apply less magnetic "pull." by making them smaller (you may need more than one magnet per tube to fix each CRT's convergence) When you have each CRT tube's convergence right, apply some clear silicone adhesive to the magnet and, permanently affix the magnet to the now "fixed" CRT tube exactly where you placed the magnet to obtain the best convergence on the CRT.
(Do not adjust the "Green" CRT unless you must, as it is used as the color line to adjust other lines to)
