Just encountered this issue a few weeks ago, happening sporadically. Some nights it would freak out, some nights it wouldn't. For my situation, though, the problem would be solved by simply taking the batteries out of the remote. Funny enough, when you hit the power button on the Roku remote (or in this case, the Home button because we had an older model w/o an actual power button) that would turn on our Vizio TV and go straight to the HDMI port where the stick was plugged in. Now my wife thinks our condo is haunted because the TV rando turned on the other day w/o her touching either the Roku or TV remotes. And I can use the app, instead. But I'm old and used to using remotes, not phones and apps for controlling devices, so I rarely ever went that route. However, the issue seemed solved when I turned on the TV last night and the input where the stick is plugged in said "device couldn't be found". I unplugged the little cord from the back of the stick, waited a minute, plugged back in AND.... nothing. Unplugged the cord from the socket itself, waited a min, plugged back in AND.... nothing. Pulled the stick out of the port in the TV, waited a min, plugged back in ANNNND.... well, you get the point. Safe to say that if anyone encounters this issue from here on out, it very well could be your stick telling you it's about to bite the dust. BUT I'll admit that we had the stick for 5 years and just now encountered this issue so I'd say for $30, we got our money's worth.
