SOURCE: convergence problem with my jvc tv

Its actually a easy repair but its recommended that the convergence resistors need replacement as well. You can get the parts at the following link and they provide free detailed instructions with pictures. You need two STK392-110 Convergence ICs and you would need the JVC convergence Resistor kit #1 also. Heres the link.

SOURCE: red convergence will not line up on my jvc 56 inch

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)

SOURCE: I just replaced the convergence board on my JVC

you also need to check and replace low value resistors in that circiut.they are all 1 watt,usually they get discolored when stressed.R842 2.2 ohm,R854 and R846 1.5 ohm,R850 2.2 ohm,R858 3.3 ohm,R862 1.8 ohm.they must be the exact value available in MD from surburban electronics.please note stk392-110 upgrade to stk392-150 for future referance.ONCE AGAIN CHECK ALL LOW VALUE RESISTORS

SOURCE: JVC AV56wp74 convergence. Resistor before ICs?

It's recommended to replace all the defective parts first because if you only replace the defective resistor, it might burnt again if the convergence IC is shorted internally. I would also suggest to measure the other low value resistors with multimeter.

Check all of the large resistors on the convergence board. Usually at least one will be fried. Most likely, the 2.2 ohm if I remember correctly. Of course, make sure all the plugs are correct and plugged in.

I have a JVC AV-56WP74 Rear Projection HDTV Ready Television...I had a problem with the convergence with dual pictures on screen...I replaced the convergence card with 110's.....This fixed the screen...


The STK392-110 are the stock ICs for your JVC. Chances are one or more of the feed resistors are bad. JVC TVs will usually have at least one bad resistor when the original ICs fail

Red Wavy lines running across the screen...


Yes - - that indicates one of your convergence amps have failed. That unit takes two STK392-110 Sanyo amps which I personally would replace with STK392-150's for greater reliability. Also check all of the return resistors in that circuit 1.5 ohm 2w and feed resistors 3.3 ohm 1w all are flameproof. You'll likely find that one or more of the return resistors are bad, with suspecting the red is the failed amp check in particular R846 for change in value or open.

JVC AV-56WP74 56 in


You don't have to replace the board, just the amps. This set uses two stk392-110 Sanyo built amps. You will also need to test and possibly replace one or more of the 1.5 ohm feed resistors in that circuit.
If you're doing this at component level try Acme in Florida for amps and resistors: 1-800-575-9833 http://www.acme-sales.net/index.shtml and if you're doing this at modular level send it to PTS http://www.ptscorp.com/ 1-800-844-7871
Good luck!
