A:Answer Actually if you look at the back side, lower left corner if facing the screen or lower right corner if facing the back side, I believe there is a small square button that is power on/off. It is not labeled but if you use it that is what it does. And it can be easily reached while standing in front of the TV by just reaching around with your hand and feeling for it. At least that is the case on our 65" M series Visio we have and what I hope to find on this one after my wife unwraps it for X-mas.
