I'm having the same issue, and I did change the power settings and etc. It will play great for 4 days, then when I go to watch live TV or Hulu, I get the message that it can't play at the moment. I have to unplug for a few mins, plug back up then everything works fine...I shouldn't have to do that for my TV to work. Plus this is my second one, the other just stopped working after 2 years
