without warning the roku ultra box shuts off on its own and i have to unplug it and plug it back in to restart it...no specific length of time between power off, just really random...any advice with what's wrong with the box
That is certainly unexpected behavior. I do have a question, though. You say it "shuts off." The Ultra doesn't have an "off" mode, so I'm curious if power has indeed stopped, or if the system is locking up with a black screen. That might not seem like a difference, but it is.
If it's the former, that could be the external power supply. If it's the latter, while it could still be the power supply, it could also be the device itself.
Does the situation you describe as "off" involve a truly black screen? Or is it one of those "looks black" screens? You know, almost black, very dark, but not completely black? Like when you reboot your computer, the screen goes black, but not really black? Is it like that?
