JVC av56wp30 56" TV, no red convergence control



I have a customers set in the shop, that the red convergence is way off, and the on screen convergence settings will let me move the red from side to side, but the up-down controls don't work at all. I am guessing a chip or other component in the convergence circuit has popped. Anynbody seen this in this model? Thank you much...
