JVC AV-56WP30 56 in. Green Convergence off

I have tried correct the convergence manualy, but I cannot get the blue and red to line up with the green, which appears to be off center. Any suggestions? Can I replace the board..or must I suffer the $400 repair cost??

    Thanks T.



    I am planning to have someone look at the set this week to determine what it will take to fix. Your advice on paying a few hundred vice a new TV makes sense, especially if you think a fix can last 5 yrs or so.



    thanks again!

Remove front grill cover---look just inside--If your model has the
convergence board up front,then you might change the board
instead of re-building it.Depends on price and availibilty.....

If you want to pursue repair,let me know......T.

    The convergence PCB has 2 large STK IC's on large heatsink...T.

  • Vista Electronics Nov 05, 2007

    Make sure IC's are first quality, OEM or better. For instance,

    Jvc original STK392-110 can upgrade to STK394-160E. I use

    Hitachi brand with excellent results. Note: hardware may need

    to be replaced due to thickness of new IC = # 3 metric X four

    plus washer & lock washer.



    Be sure to specify to repairman---do not use generic IC's !

    Get proof of replacement quality = package they came in &

    look at what is mounted on heatsinks.......T.

Convergence on jvc av-56wp30


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
