JVC AV-56WP30 56 in. Rear Projection

The convergence is off and when I go to crrect it manually, it won't work. The green + is not cnetered (at the 5 position) and I cannot get blue or red to meet with green. Others (1,3,4,6,7 and 9) are aligned okay. Any advice? Is it worth the maintenace of $400+ or get a new TV??? Thanks!

    hi, i have the 56wp74, red was out of wack, i properly installed new ic's, and now the green is curved, the red and blue is out of wack too. i tried to manually adjust in the service screen, without luck. i tested all the resistors, and the only two that dont seem right are the 220 ohm on the r873 spot on the board, and the 150 ohm resistor on the r863 spot. both read 89ohms instead of what is on the resistor. could that be the problem, and where can i get thoes resistors?

Have a JVC AV-48WP30 rear projection tv set and the green seems to be out of place. the green image is lower than the others and is in a wave shape on top of screen and bottom.When I adjust the convergence...

Your convergence IC's are bad. If your not doing the work it will probably cost in the neighbor hood of $250.00 for a service company to do. Not a major repair.

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,

Green tint on Samsung Television

Hi sbatsch,

Not to worry - this problem is very common with projection TVs and is easily fixed:

The reason for the green shadows (and the resulting wrong colors) is that the three color tubes (red, green, and blue - the three colors of light that combine to form all the other colors) are not lined up exactly - this lining up is known as "convergence." You can fix convergence automatically or, if it doesn't work to your satisfaction, manually. Here's how:

1) Press MENU.
2) Go down to CONVERGENCE (using the up and down arrows)
3) Select it (usually with the left or right arrow)
4) Go down to AUTO and select it - the process should take about a minute.

If this doesn't work, then try manually:
2) CONVERGENCE (as above)
3) Select MANUAL
4) Using the number keys, SELECT, and the arrow keys, adjust the alignment of the different color crosses - the goal is to make them appear white (meaning that the red, blue, and green are exactly aligned on top of one another).

Here's a link to the JVC user manual that will explain the manual convergence adjustment in more detail.

I hope this helps - please let me know if I can be of any further assistance.

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.
