This just happened, the power goes off then comes back on.I tried it on another plug and sometimes it worked and sometimes not(?)There was power before and nothing has changed but now off and on,it's crazy.
Could you tell us how your Roku device is powered? Is it connected to the USB port of the TV or to a wall outlet? In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.
Using the included power cord and power adapter, we suggest plugging your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV. This means your Roku player will be up and running faster than it would be connected to a TV.
@Richpartist, when you say "the power goes off then comes back on" what do you mean? Does the picture go black for a few seconds and then come back or do you actually see the startup animation when it "comes back on"? If the picture is going black for a short period of time and coming back try a new HDMI cable.
