Your tv is one that uses 3 small tv tubes to generate and project the image on the screen. Because the tubes are a little apart the image that they project would be off for each color so to make it clear they have to distort it using a special board called the convergence board. To move the images of the each tube requires a lot of power so circuits used to do that are subjected to great stresses and fail on a regular basis - in your case the circuit responsible for the blue tube.
Actually it the case of your tv the failure is such a common occurrence that specialized companies have made repair kits just for them - you buy one of the kits, you open the tv and replace the components with the ones from the kit. The kit is quite cheap - $70 - but it should be installed by someone who has done such delicate solderings before.

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)

Im seeing duble words,how can i fix it?


Hi,
There should be a convergence adjustment on this set. It will have a "cross hair" type pattern
You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White.
Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double
images should be greatly reduced or eliminated..
Hope I've helped you,
Best Regards,
Mark

Toshiba 65H81 convergence issue


Does the blue and red crosses move at all ... eather vertically or horizontally. if they move at all then it may not be the chips.. could be a resistor. if the crosses dont move then it probally the ic. these chips run about 7 to 45 dollars apeace depending on type. at our shop we charge around 125 to put in.

PT 47 convergence IC's? box? both?


Always suspect the IC's first, digital convergence prblems are actually pretty rare IC's go everyday. I'd check partsore .com Generics usually work fine, they are probably STK392-110's but check to make sure.
