My convergence dislay shows red is aligned buth the blue green are not aligned. The blue is off on the top & bottom which May be a bad convergence IC. The green however off on the top & bottom, is this convergence also? Thanks,
Your TV most likely a convergence failure. ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Here are some photos of convergence problems.

Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This isJVC 56wp30 convergence - 0667c5f.pngroblem. 
SOLUTION
You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Turns out there is a third IC chip. A local repairman told me about it and he changed it. If you change these because they will die due to heat, search your tv and changed everyone you find. They are cheap and easy to change.
My picture now looks brand new. Thanks for your help gang. NICE JOB!

I tried to adjust the convergence on my TV. I can move the blue horizontallly and vertically but I can only move the red vertically.
Do I need to slap the TV on the side to make it move horizontally or should I take it to a service person because I don't know how to use any equipment to fix my TV. Please help!!!
I've had the same JVC issue. Red only goes up and down, blue lines up no problem. Also if I move the middles ones (3,6,9) they all move! Is there no simple way to fix this? I see the technical fix, but it sure looks complicated, and the $300 fix doesn't work for my mom living on SS and me as well being a single mom/widow on SS. Know what I mean??? Is there any other solution?? This tv is only 3 years old!
I am ordering IC's myself today and will report back. I hope to hell this fixes this 1800dollar tv. You guys are the best!
Exact same problem! The red moves only up and down, and it's impossible to line all the crosses up. I'm going to contact JVC, and see what I find out. Jag - keep me posted on your progress, I'll post back if I find anything out. I did recently switch to Direct TV - think that has anything to do with it?
Well, gang. I changed out my two IC's. The picture got a "little" better. Turns out, there is another one of these ic's in the tv. I took it to a local repairman. He was most impressed I changed both of the two chips. Had I known there was a third, I would have done that one too. Either way, I was out the door at the shop for 120bucks because he changed the third chip and adjusted the picture. Now the TV looks as good as it did when it was new. I decided to keep it after all.
So, Be on the lookout for this chip. Search inside your box and see how many of them you can count. I think it has 3 or 4 total. Change them ALL just because the heat kills them and they are cheap and easy to replace.
Hope this helps someone out there. You guys were a BIG help and saved me tons of money and I learned a thing or two along the way.
Best wishes in '09
