I will presume the actual model number is 50EX10B; this is a older set and if it has a convergence problem that will not adjust it uses three of the STK-4274 convergence IC'S. This set is a little different than the later ones: it uses one chip for red, one for green, and one for blue convergence. If only one color is way off and will not adjust you can replace the appropriate chip for that color and be back in business. Repair would involve getting the entire Chassis up so the bottom faces the back of the set and unsoldering the chip and replacing it etc. It depends on how technical you are and what skills you have at soldering etc. These chips on EBAY are less than 10 dollars each--if you get a chance take a photo and post it HERE for me to see what it looks like--a picture would tell me which is bad and we could proceed from there. Feel free to ask me questions---I am here to help. SD TECH

Hello I have a rear projection Hitachi TV from 2000/2001 approximately 48 inches. I am getting a red shadow cast all over the screen, I have tried the convergence button but it is not helping.


Hi, thank you for visit fixya.
STK IC's need be replace, and possibles resistors burn too.
We call convergence problems.
For best results, take your tv to near tv service and request help for convergence parts, or you can find at encompassparts.com , just provide model number tv and they will help you.
Any question, let me know please.
Thank you

My Hitachi TV Model #51F500 is showing shadows and double lettering (in other words a terrible picture). Please help.


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Part number for IC module Hitachi 50EX12BA?


The Hitache 50EX12BA uses 2 IC's labeled STK392-110. If you are looking in the back of the set, the convergence IC's are mounted on the large heat sink on the right side. If one of the IC's has burned out, go ahead and replace both IC's with the newer improved STK392-150 IC's. These IC's are very common and can be ordered from almost any electronics parts supplier. When installing the new IC's you will need to clean off the old heat sink compound and apply fresh compound to the back of both IC's.

Yes you can safely clean tv, just remove front speaker panel and you should see screws holding up front prot. screen. Becareful not to snap screws. You can take screen out and there is a mirror that you can clean and 3 lenses.
