I have a JVC HV-53Pro and the picture went out of alignment on the right side of the screen. When I go into the menu and check the CRT color convergence the red crosshairs are way out of line on the right side and slowly get better as you move left, however they never get perfect. Any ideas on where to start looking?

What are the Convergence IC's and how do I replace them?

STK392-XXX's, usually in JVC STK392-110's. Their 18 pin multi-amp IC's. They solder in and out. The forum has the schematic for this set.

Any idea where the schematic is in the forum? I looked through 20 or so pages and could not find it.
