I have a JVC AV-56WP74 Rear Projection HDTV Ready Television...I had a problem with the convergence with dual pictures on screen...I replaced the convergence card with 110's.....This fixed the screen...

The STK392-110 are the stock ICs for your JVC. Chances are one or more of the feed resistors are bad. JVC TVs will usually have at least one bad resistor when the original ICs fail

Blue shadow across my screen

Go into the convergence function from the menu and see if it works. If it does not then the convergence board has a problem. JVC still sells the part.
