The question is old, but this might still help someone.

I had to replace mine on the 55" model, and I went with the STK 392-150's. The cause of failure is normally overheating, and with mine they did a lousy job of applying thermal paste to the backs of the ICs. (as you can see in the pic, so I'm sure that is why they failed). Depending on where you buy them, you can probably find the 150s or 180s online for the same or lower price anyway, so go with the higher power rating since that means they will likely withstand more heat for longer. But make sure you buy a good thermal paste and apply it evenly and correctly. Mine is working great now going on 3 months, I used Tuniq TX-4 paste. BTW, I'm a lousy solderer but I removed the old and soldered-on the new chips by hand. It looked pretty rough but ended up working perfectly. Anyone can do it!

The recommendation of the manufacturer is to replace the ICs with the same part number. In this case, use hte STK 392-110. Some people "upgrade" to the STK 302-150 because it can handle more power. The added power handling will not significantly increase the time of the set at all. This is your call. Either IC will work as the pin-out is the same for both.

I'd use the original part number.

Replace the convergence ICs and resistors. You can get the JVC repair kit called the AV48WP30 - AV65wp30 convergence repair kit from which contains the ICs, Resistors, and the CD with repair instructions.

I have a jvc av48wp30 tv and need a wire diagram

Looking the convergence board from the side of the resistors (The chips will be behind the resistors), you have from de left to right:

1.5 ohms, 150ohms, 220ohms, 2.2ohms, 3.3 ohms, 220ohms, 1.8ohms, 220ohms, 150ohms, 150ohms, 1.5ohms, and dispose horizontal in relation of the other resistors (the one near to the Ic is 2.2ohms and the other is 220ohms).

Hope this helps...

JVC AV48WP30 convergence ic

I'm in the process of trying to replace both convergence IC's in my JVC also. I was able to buy both IC's (they look like black semi-rectangular components with 20 pins sticking a computer chip only much bigger) at a TV repair shop for about $15 each. They were clearly labed STK392-110 (but could be 150 or 180 if you wanted to upgrade).

There are a number of different STK type parts. You need to look on the old ones for the part numbers. May have to dissassemble the heatsink to see the number. STK is pretty good about its numbers and you should have no trouble finding them.
