Question about Vizio Televison & Video
I've tried doing the unplug/power button reset and also tried turning the backlight setting all the way down. I'm unsure if this would be the main board, backlighting boards, or what. Many thanks!
This is a trace line, in old days this would be a function of the flyback circuit but today it is digital. Could be a bad IC chip may be a poor solder joint. Some components are tough to work with as the controller is small with many solder joints. Sometimes a piece of debris can cause this. Check for PAL setting as this may be off, in the menu. Lastly the timing may be off from a out of spec circuit, clock circuit.
