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?

  • dac43160 Apr 06, 2008

    The left upper side of the screen is streaking.

  • jponthelake Apr 08, 2008

    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.

THE VERTICAL AND HORIZONTAL COLORS DO NOT LINE UP.IT KIND OF LOOKS LIKE THE PICTURE IS IN 3D.

What you most likely have is a convergence problem. The convergence circuitry is used to align your colors. What you describe sounds like that circuit has failed. Here’s a link to a decent video that will give you an idea of what is needed to fix it: http://www.youtube.com/watch?v=esk4nYZKFcg

JVC MODEL # AV-48WP74 48 IN. BIGSCREEN TV.

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
