Re: JVC projection tv

Mike, convergence adjustments are in your menu, usually under "video" settings. You have to adjust red & blue onto the green, when you`ve done it correctly the "cross" will be pure white, if you cannot move either of the colors left, right, & up, down then the convergence IC`s have failed and will have to be replaced, hope this answers your question, BMW Rider

Try adjusting the convergence. If it won't move see below- (or hitting Magic Focus for some Hitachi’s) JVC usually have a sperate smaller board for convergence

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

I have jvc-56wp30 the color convergience is way off like a 3d picture. it will not converge.

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 projection 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 can see some more examples and find a fix using this link on Fixya

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,

Remote LOST - need info on what button to press...JVC AV-48WP30

There might be some features that the universal remotes aren't able to do. To perform the convergence alignment you should have the original remote.
Do you have the user manual or service manual?
The service manual will explain this process better.
