    Could any one tell me how to converge a Hitachi 50UX22BA tv. The blue
    is out of whack and the auto converge does not help.
  2. The answer to your question is not simple. You need to get a copy of the
    Hitachi service manual and the convergence adjustment guide. IF the
    convergence is very far out, you need to resolve the service issue before
    converging the set. If you have never dealt with these sets before I
    suggest you contact a servicer who has or you will likely waste a lot of
    time and perhaps make the problem worse.

    You need to troubleshoot and repair the fault in the blue convergence
    circuit first.
    Then follow the procedure in the service manual to fine adjust the blue back
    into sepcification.

    You will need the service manual, a full understanding of the convergence
    circuit system used, and o'scope, and good signal tracing capabilities to
    track down the problem and effect a safe and proper repair.
