Double vision On JVC AV-56WP74 56

I have a JCV television. Model# AV-56WP74. The red color is to the left of everything. All figures and letters look like double vision. The converge will not merge the red with the other colors and the manual does not work either. I have only had it about 2 yrs. Thanks for any help.

You have an convergence problem, There are 2 IC's that go bad and a few resisters that can change value. If you flip the board with the Chips inspect the pins for cold solder joints. The IC's can be purchased from matelectronics

Resolder the cold joints if you can see small
rings around the pins of the IC, this corrects this problem without need of a service technician.

sounds like a solder related issue on the convergence ICs. They are acessed through the front of the TV behind the speaker grille and then remove the small acess panel and you will see the convergence amp board with the two ICs on it.
