of the ic01 on its pin75 the pin that corrects the ew
check that r540 is not open on the side
of the micro.
you have the kia4558 it has to have 28 v on pin 8 and this component is an amplifier of the error of the pincushion effect and its most deteriorating components are capacitor c408 c308 transistor q303 q302, the q302 goes to the heatsink and works with a high voltage maybe leaks or the diode d302 are also components associated with this component kia
