Did you replace the convergence resistors with the ICs? The resistors often get increased resistance when the ICs go out and if they dont get replaced you can have a next to impossible time adjusting the convergence properly, as they have to be within 5% tolerance. You can get the resistor kit for your JVC at the following link. Its Called JVC convergence resistor kit #1. Heres the link.

Color will not match up


if your talking about the sets convergence does not line up and it looks like a 3-D picture than The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!
