Hi, I have a Vizio TV E3D420VX and it has symptom as below:
1. When I press power button, backlight on, 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??
