Hello,
I have a Vizio tv M550VSE and the screen is flickering between bright and noticeably dimmer. The picture never goes away, just flickers bright/dim. I took the back cover off and inspected the PCB's, no issues observed........all capacitors look perfect. I am willing to try a new PCB if I can determine which board. I see a PSU board and the LED driver PCB. Photos attached. Which PCB is most likely the culprit?
