On the 48WP30, you get to the convergence board through the front. Around the back edge of the speaker grille are four screws. You remove these screws. Then you remove the two other screws at the top of the speaker grille near the center panel underneath the front av input door.

THen after you get the speaker grille off, you take the four screws out of the wood panel door and take it off:

Those two big black heat sinks on the front there are your SK chips...on the convergence board of course. pop it up from those four tabs, and that will let you carefully move the convergence board so that you can reach in better, and unhook the three plugs on the right side (looking at it from the heat-sink side) behind the heatsinks (one for red, green, and blue each) and then on the other side of the board, you disconnect the other two plugs, but there's one that you actually have to trace back into the inside of the TV and unplug from a vertical standing board, since the socket is not on the convergence board itself. let me draw up a little graphic real quick.



Hope that helps.

When convergence output ICs got failed, tv shows double image or 3D like picture. Replace convergence output ICs in tv to fix the issue. Local tv repair shop will replace it for you.

My jvc 56" proj. tv pops several times when i turn it on but the screen stays blank


Ok, I suspect one of the two convergence chips is shorted, this is usually the most common reason the light (blue?) just blinks.

I can tell you in a easy way how to prove this without replacing any part--

What kind of skill do you have?

This entails removing the front grill under the screen and disconnecting the Convergence board behind the inspection plate.

Red convergence will not line up on my jvc 56 inch i art projection tv model # AV-56WP74. PLEASE TELL ME WHERE CAN I BUY THE KIT SO I CAN FIX IT MYSELF!!!


You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

Convergence problem


Hello,

Did you lock the adjustment into the TV's memory? This step is the most often missed. Please follow the directions on the Users manual or on the service manual on how to set your memory to hold the configuration.

Find the menu item on setting the convergence adjustment into memory (the menu should have an informational screen on this topic)

I hope this helps

Thank you,

Tv comes on then goes black power light blinks on and off modle # JVC AV-56WP74 56


Check the coils on the main board. Coils mean round ferrite donuts (1 inch or less) with copper wires on it. I have seen this come out.
if not check convergence amp ic's
