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?

Convergence ICs and resistors need replacement. Very common issue. The AV48WP74 -AV65WP74 convergence repair kit from www.tvrepairworld.com has the 2 ICs and associated resistors plus the CD with repair instructions.

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


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,

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.

The convergence circuit needs repaired. I did the same job yesterday on this model. I not only replaced the convergence ICs, but, I had to replace a couple of resistors and a coil. The convergence alignment was minor after that.
