    Default hitachi convergence ic chip is there a way to test ic chips



    Hi, I have a Hitachi 50ux26b manufacture date 1998, I am having issue with 1 of the 3 chips there is a blue line on magic focus out of wack indicating that I have a bad IC chip, I have found that the chip is available to replace. Part #: 2003191 INTEGRATED CIRCUIT CHIP STK4274 I have taken cover off rear of tv and located all 3 chips assuming there is (1 red, 1 blue, 1 green) I would like to figure out which chip out of the 3 are bad is there a way to test and find out which one to replace I don't want to replace all of them. are they labeled red blue green on each chip/board or do I have to remove all of them and use a meter to find the bad one, and how do I test each ic to eliminate the faulty one.

    For the price of those convergence IC's wouldn't it just be easier to change both of them.

    Yep Fernbay lol .If you have to give warranty you change both chips or it may bite you on the bum in a month or two.
