    Thanks for the info..But im curious about the difference. Someone will say replace 2.2k ohms 1w and others will say just 2.2 ohms. 1w..is there a difference between 2.2k and a 2.2 ohms without a k?..Im not a electronic guro..cause i have change my 2.2 ohms to 2.2k ohms, now i have no pics and a thumping noise off my speakers:(

    THanks! Slinteriors

    Ok, I replaced two of STK392-110 ICs to STK392-150 ICs and also replaced couple of the resistors, 2.2 and 1.8 ohms. Still having convergence problem:( At this point, I think Im just going to toss this unit out. Blue or red color will not align. Please Help!..thanks

No, they are special resistors they need to be metal film 5% 1 watt resistors. Radio shack wont have them. You can get some at the following link, but they have a 10.00 minimum order so you may have to purchase a couple exrtra for spares but they do ship for free. Heres the link.

    Yes there is a big difference between the 2.2 ohm and the 2.2K the 2.2 ohm is just 2.2ohms but the 2.2K ohms is 2200 ohms. thats a big difference and your set wont work unless you go back with the 2.2ohm 1 watt resistors

    There must still be a resistor or two that is either open or has increased invalue. you may need to replace the convergence board itself as the enclosed portion of that board has the memory Ics incased in the metal box may have been compromised when the 2.2K ohm resistors were installed the convergence board for your model is available.

Replace the convergence IC's STK392-110.
AND Check the resistors 1.6ohms and 2.2 ohms.. If open replace them.

My tv is 3D.....I purchased the repair kit, but it did not come w/the right resister. I went to radio shack and they can't read the # on the olld resister, so I need to know what number should it say on...


What is the location number of resistor on the board? I assume you are replacing the STK ICs
is one resistor in that circuit? It has to be a low ohm resistor What are the Band Colors on resistor?
Example brown,red,black 1.2 ohms

HAD MY CONVERGENCE ADJUSTED BY REPLACING SOME PARTS. I NEED JUST ONE OF THE CROSSES ADJUSTED IN THE RIGHT UPPER CORNER OF THE NINE CROSSES


Ur tv still have convergence problems,if u can't reajust manually crosses or auto convergence.U must have 2 not just 1 STK convergence ICS to be replaced,all the resistors must test by the Ohm mulitimeter to the right resistance of the resistor's and replace them as require.

I had a convergence problem on my JVC AV-48WP30, and followed the instructions posted by SD Tech. I used STK-392-150 chips and I replaced 1 burned out resistor that had no bands, but was marked 1.8 ohm J...


Yes, it does not happen often but you may have installed or got a new chip that is bad--you did apply heat sink compound to the new chips?

Check all the resistors carefully when you do this and double check all the soldering you do.

Let me know if you need help.

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...

Replaced the convergence ICs


If you replaced both ICs you may have a blown resistors usually the 1.8 ohm 1 watt resistor or the other ones next to it will be blown if you still cant do alignment after repalcing ICs

Jvc av-48wp30 convergence problem


1. if the 1.5 ohm resistor was open, then you may have fried your new convergence ic's. Sorry
2. bettween a 1.5 - 1.9 ohm resistor will work
3. press sleep button, set to 30
hold down video status button and press display on remote
select convergence from the new menu and hit OK.
Do fix the convergence before you try to align the convergence or it will look horrible after you get the circuit fixed and will be harder to align.

The white button is there because the DCU (digital convergence unit) can be erased by holding that button and turning the set on.
I WOULD NOT RECOMEND THAT AT ALL!!!!!!!!!!!

Hope this Helps.
