Convergence problems on AV-48WP30

Mark Venable Posted Apr 10, 2005

Can't adjust the red horizontally

Convergenge went out suddenly about a week ago. I can adjust the blue horizontally and vertically. The red will only adjust vertically. However, the horizontal is way out of whack. Any ideas? Thanks

    I have a HV-53 with the same convergence problem. I would highly appreciate if someone could send me schematics, guide and info on the "IC's" that have been mentioned throughout this thread. Thanks in advance!

    Is this issued being fixed? I haven't heard to many success stories. I have a JVC AV-56WP74 and am having the same problem. Is this something that a person with no tv repair knowledge can fix? If so please help me!! Otherwise does anyone know the average cost this would be?

    I'm having convergence problems on the model JVC AV-48wp74 but it is the green lines. The red, blue works fine but the green won't line up it looks like it is sagging down from the top of the screen. Please help, send a repair manual, or schematics. thank you. can you send a copy to this email address too? khen874066@aol.com

    I'm assuming I've got a convergence issue with mine simply because when I bought the TV, it had been repaired for a convergence problem. The green is fine on the outsides, but goes "skinny" in the middle. It's making a concave shape would probably be a better way to describe it. The green is also shifted somewhat but the main problem is the way green is being displayed. While I'm here, I'm also wondering if anyone's found a way to use the DVI port with a computer. My video card has the HDCP circuitry built-in but for som reason this TV was designed not to accept a computers video signal. This is not that big of a deal, just asking the question. Getting my TV fixed is more important. Thanks, in advance, for whatever help I can get.
