FIXED!!!

I spent $32 on a new power supply board from Shop Jimmy and it worked! And while I'd love to know which specific component on that board failed , I'm pretty stoked. I got this TV free from a friend who didn't want it when it quit working. Vizio didn't want to pay to fix it so they just refunded him his money.

WOO HOO!!!

Hi! I have a symptom in Vizio E3D420VX TV
1. Press power button, power white light on and Vizio V logo is on the screen
2. Logo goes off, power white light blink one time.
3. Power goes off by itself and doesn't come up
4. Same symptom in every time when I press power button.

Is it an exactly same symptom as you?
Can it be solved by replacing the power board?

Or, do I have to replace the main board???

My problem was different. For me, only the white power LED blinked for a few seconds and then turned off. The screen never showed anything.

Hey everyone, I replaced the power supply board as suggested, but that didn't fix my issue. What should I do next?

This sounds like my issue. So far, a new power board hasn't solved the problem.
