Question about Hitachi 46UX24B/25K 46" Rear Projection Television
Usually there are 2 convergence IC's, labeled STK392-110. Each IC has 3 channes. Each color needs to be corrected 2 ways, vertically and horizontally, so 6 channels are needed. usually one IC does red, red and haf of green while the other IC does the other half of green, blue and blue. If the red colors are off, change the IC closest to the red jack. If the blue is off, change the IC closest to the blue jack. If the green is out, you have a 50/50 shot at replacing the correct IC. It is recommended to use the STK392-150 when replacing the IC's so it might not be a bad idea to go ahead and replace both with the newer numbers.
