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)
Thanks for the info, on average you know what that job would cost from a repair shop to do (time, looked up parts seems to be relatively cheap). Any more info appreciated, bought the TV for my sons apartment, but dont have the time between work and other time occupations to do the repair myself as its been a while sence ive needed to soldier anything (did a video card volt mod a while back, but other than that im sol with a soldiering gun (coming from a welder heh.))
I have the same problem with my Samsung 47" Rear Projection LCD HDTV (HCN4727WX/XAA). I also tried to adjust the convergence with both red and blue. The red adjusted, but the blue didn't even move. The perfect focus only reached 4%. How was this problem resolved and how much did it cost????
Thanks,
