Only to turn off and on. Previously it might take 3or4 tries for picture to turn on before it worked. Now there is no picture or sound.
Not 'too far gone' yet but the nature of the failure points to the modular switched mode power supply,
Look for a block assembly with larger components and several connectors that is bolted onto a larger panel.
These are purchased from other sources, not made by Vizio.
Look into the guts of this assembly for cylindrical components with plastic foil and an aluminum top, mostly mounted vertical to the board.
Examine the tops of these for any dome-like appearance; this is a sign of failure since these should be flat.
They are inexpensive (one reason they fail) and this failure can be prevented by spending another dollar or two in the manufacture of them.
The Vizio 1080P HDTV offers a variety
of features and input jacks that make it a true multimedia centerpiece.
Occasionally, however, there are a few scenarios in which the screen
blacks out.

After testing what I was able to and could find nothing wrong, I put tv back together and it worked until moved back in place, then it started acting the same way. I believe there is a faulty connector or component.
