I'Art Model # AV-48WP74

Suddenly, my I'Art large screen TVModel # AV-48WP74 starts giving me fuzzy color and picture. It seems as if the colors are all out of sync; how do I go about trouble shooting the problem?

    The left upper side of the screen is streaking.

    Unit fine when shut down. Upon repowering a few hours later, the convergence was completely out.

    Tried powering down for a few minutes - no help.
    Tried auto convergence setup - still, not even close.
    Convergence appears to be normal near center of picture, but the lines grow increasingly apart as one looks to the top or bottom of the screen.

I had a problem with my TV colors not lining up. One day I turned it on and the green was out of wack. I checked this message board and replaced the STK chips, bad soldering and all led to me just giving up on that and buying a whole new Convergence Board ($185). I just plugged this in and though now my Green lines up okay, my red is out of whack. Is there something I am doing wrong? Can anyone help me? Did i miss a step? Frustrated......Bruce
