JVC AV-56WP74 convergence board...add'l question

I am having the same problem with the red lines not aligning when doing the convergence procedure. When watching TV their is an awful red hue or shadow on the screen. This is the post that I have questions about: "Order online part # SSB-5068A. This is the ENTIRE convergence board with new IC's. Cost you about $140 (from vance but is a lot less hassle than you trying to soldering/desoldering parts. Only thing is, next to the 2 large heat sinks, there is this large silver component that you need to unscrew from your old board, and unplug and attach to your new board." 1. The baldwin link... * it has a different part number than the ssb-5068A, the link shows SSB-5068a-M2-R. Is this the same part? If not, I am not able to locate the part. 2. What does the convergence board look like behind the tv?

Re: JVC AV-56WP74 convergence board...add'l question

I just removed both of my 110 IC's and replaced them with 150's. However in the process of removing the solder from the old board, I may have damaged the pads/vias where the pins make contact. Be careful of this when removing solder. I also blew 5 resistors after plugging in the new IC's.

If the red line looks like a swoosh of red across the screen it may be the convergence Ic having an issue.

Convergence problem


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,

JVC 56 inch projection AV-56WP74 red color not aligned

I have the same tv set and about 4months ago Ihad the IC STK392-110 replaced. I was told that it was the most common problem with proj. tvs. It did solve the probem until last night when I went into the menu to change a audio setting and stupiditely accesed the convergence setting and decided to do an auto adjustment which mesed up my beutiful HD picture. Now I have the red out of alignment ad even after I did a reset and multiple manual adjustmets it is still off at the top and bottom af my screen.

Jvc 56wp74

sounds like a solder related issue on the convergence ICs. They are acessed through the front of the TV behind the speaker grille and then remove the small acess panel and you will see the convergence amp board with the two ICs on it.

Take the board out through the front inspection hole. No screws holding board. Middle large plug disconnects from chassis, not converge board. All other plugs come off converge board.

If the large plug is a problem, just hang out the front and solder.

Be careful with foil on board, crappy board.

Pacific Semi for ICs.

JVC AV 56WP74 Problem after fix

Will the colors move into alignment controlling them manually?
If you can get the colors to align but they simply won't hold it's a matter of programming. If they won't align you still have a failure in the convergence circuit. If red or blue will only move so far but not close enough to align you have an amp problem.

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 and if you're doing this at modular level send it to PTS 1-800-844-7871
Good luck!

Double vision On JVC AV-56WP74 56

You have an convergence problem, There are 2 IC's that go bad and a few resisters that can change value. If you flip the board with the Chips inspect the pins for cold solder joints. The IC's can be purchased from matelectronics
