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,

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.

A repair facility will charge 400 to 600.00 for the repair. Or you can repair it yourself if you can solder. As both convergence ICs need to be replaced. They are STK392-110 you can get replacement ICs at the following link with free instalation instructions with pictures so you can do the repair yourself. Heres the link.

JVC AV-56WP74 self check question


Each picture tube (red,green,blue) has a magnifying lens assy that sits on top. On each lens assy is a manual focus adjustment with a wing nut that tightens it. The image bounces onto the mirror and shoots it onto the front screen. If you're not a technician then I don't advise you to do this adjustment. You could touch something in the high voltage by accident.

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
