Check the resistors on the convergence board by the IC's. Chances are that 1 or two of them are open. If you can't fix it, you can remove the convergence board and send to PTS electronics and have it rebuilt.

Jvc av48wp74 horizontal convergence unadjustable after after repair


you have to lift one side of the resistor from circuit in order to measure resistance otherwise a open resistor will not read open as you will be reading the resistance from the surrounding circuit. Always lift one side of a resistor out of circuit when testing with a ohms meter.
