Possible your tripler control is going out .This part splits the high voltage from flyback transformer into 3 high voltage leads to feed to the three picture tubes .The side for the red is likely to go out causing red picture tube to overdrive in red retrace lines..That or RED CRT BOARD is bad

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.
