Input: UPDATE: Our unit failed (won't power on, no lights, no sound) after just a few weeks of use. It was working fine this morning, but now will not power on at all. Before that, this was a four-star product, working great for what it is with a few design issues which would have made it a much better unit. Now it is zero stars, and I can't say I'd take the chance on it (or Vizio as a brand) ever again. Yes, I unplugged everything, and plugged it into a new outlet (which I know works because that outlet was powering my Apple TV before and after troubleshooting with no issues). Yes, I tried the original remote AND the buttons on the top. There is not even the little white LED light that comes on on the left of the sound bar when it turns on. This unit is dead. Apparently the handful of reviews on this which say it will suddenly fail are correct. I'm now looking to see if Amazon will help me get this lemon off my hands and get a more reliable unit or if I need to deal with Vizio.

STAY AWAY FROM VIZIO: Won't power on after two weeks
