I art JVC 46 inche double vision

If you do not have hand soldering skills or know how to use a multimeter, I would suggest to replace the whole assembly.
If you know how to solder you can just replace 2 ICs that are mounted on the big black heatsinks and possibly 1 or more resistors.

Converge problem how to fix JVC AV56wp74

There are two of the IC's in the tv. First things first, turn the tv off and unplug it. Wait a few minutes, then open up the back by unscrewing the screws in the back panel. Now slide out the wooden panel that divides the upper and lower part of the cabinet. You'll see some cards sticking out of the plastic input panel. Find the one for DVI (it's the furthest to the right and it's at the top). Unplug all of the cables that are attached to this board. If you look closely, on the top of this board (the edge facing the top of the tv) there is a tiny little square looking hole on it. Cover this with black electrical tape or something that will not allow light in. The reason we do this is because JVC made a booby trap that erases the eeprom if you try and operate the tv with the back off. If the sensor senses light when the tv is on, it will erase the eeprom. Ok well now that that's covered, the actual convergence board (the one with the two IC's) is the board in the very front of the tv. It's long and slim and you'll immediately be able to see the two IC chips. They are big black things with lots of pins and they are pushed up against heatsinks. Those are what you would want to replace. Now I've not taken the boards out before, but from the looks of things, all of the boards are on a big black plastic tray so you can take them all out at once. I don't know if you can get just the convergence board out very easily, but at least now you know where and what it is. I would seek further instruction from someone a bit more knowledgeable about taking the boards out, but that should give you enough to do until you find more help. Hope this helped!

No. You have bad convergence output ic;s and probably at least 1 burnt resistor. This liely will have to be reconvergec in the servcie menu after the aprts are changed.
