    I have the same convergence problem (second time in 4 years) I would like to get the step by step and necessary replacement part numbers if possible.

    I have the same thing going on for the second time!! They replaced two 1c's part number 392-150 last time. It is doing the same thing it was before ,however, I called JVC last week and they said the number they have is 392-110. They did offer to replace the parts for free since I just replaced them last year. I had to throw a fit , but I have had it with this TV!! The authorized repair center wants 400 bucks to put the free part in though!My hubby is going to try to put this one in but he would like to know what the difference is in these two numbers and could it be something else even though it's doing the same thing?

    Red on right, green on left, cannot correct with adjustment.Occasionally the entire picture will shift out of whack, though just the outside edges. I'd like the part numbers and instructions if possible. Thanks.

If you remove the lower front panel where the speakers are then the small access panel you will see the convergence module right there in the front. It will have the two Convergence ICs attached to that heat sink. They are probably STK392-110. Then if you would like let me know and I will post a link where you can get the parts along with step by step instructions on how to do the repair.

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.
