I have a Vizio VX32L that i plugged up into a friends house and apparently it had wiring problems cause it surge and electriclly blasted the tv. It still works but the hdmi, rca, component inputs the colors are all off and weird colors. The only input that works fine is the coaxial input for a cable from the wall. I wanna fix it myself and i was wondering if i should change the main board that has all the inputs connected to it?
