I have a Vizio tv that the logo light is flashing
My house was hit by a power surge and my Vizio tv turned off. All it will do now is the logo light is flashing and will not power up. I replaced the power circuit board thinking that was the problem, what could it be?

3) After approximately 1 minute, the VIZIO logo should stop flashing.
4) Press Power Button - TV should power on.
This procedure resets the OS program execution (power spike corrupted the sequence).
