Question about Toshiba 50H82 50" Rear Projection Television
If red adjusts but blue does not adjust in some direction one of the two STK-392-110 convergence chips is bad.
Both should be replaced at the same time (about 12 dollars on EBAY) AND THE set will also have a number of small resistors in front and around them (they are usually 1.8 ohm and should read like a fuse).
Repair involves getting the chips out and replacing them. They have 18 pins each and are soldered in.
If this told you something you did not know, rate this solution as very helpful as I do this here for free.
