Check for bad capacitors in power supply, check voltages coming out of the power supply, if voltages are good, bad main board.. Vizio's are notorious for bad main boards.

What is voltage supposed to be for P on pin on power supply?


The power on is usually 3.3vdc, but on some sets it's at 0v to turn on the set, and 5v when the set is off. Your power supply maybe ground activated. If you replaced the main board, then the power supply is your problem

Model Vizio SV420XVT1A will not power up. The Vizio logo is amber, nothing happens when you press the power button.


You will need to have the set diagnosed as there a number of things could cause this. But I would say you're looking at a power supply or main board problem. It is also possible that your key controller (side buttons) is defective. I take it the TV doesn't turn on with a remote either?

Vizio M261VP 26'' LCD TV no picture, logo does not light up


If the Vizio logo(power indicator) isn't coming on when the set is plugged in, most likely you have a issue with the power supply. Your standby power supply isn't working, and without it, you will have a dead set.
