You will need two STK 392-110 ICs. They are located in the front of the TV. remove the speaker grille and then the small access panel and you will see the convergence board it has two Black heat sinks the ICs are mounted there. You can get replacement ICs with free shipping and free instalation instructions at the following Link.

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
