    Have a 61" Toshiba Model TP61G90 rear projection tv with a convergence
    problem. Cannot converge red properly onto cross. Movement is only to
    the
    left. Cannot go right. Blue is OK. Little circle in lower right corner
    is perfect round circle for blue but an oval for red. Is this
    distortion?
    Does this unit incorporate STK**** series of convergence correction ICs
    as in Pioneer models? Any help would be appreciated. Thanks ahead. Ron.

    Yes, it uses two STK's I do believe for that model it would be the
    STK392-020, but check to be certain. Usually that's the only problem with
    those.

    Correct: Confirm the right STK # and replace them, also check the associated
    resistors with both output devices. Cheers
