I have it plugged into an extension cord with the included usb charger. I have no reason to suspect there's anything wrong with the extension cord power currently. For convenience, I have tried unplugging both it and the tv for a minute yesterday night. I am not sure if it worked today or not so cannot say if that solved it or not yet. I will know tomorrow I suspect.
By "stops working" I mean it did show the black HDCP error detected page once, but usually it doesn't. It usually just shows no picture but does have sound. We are using Sling and Discovery+ with it, we have no tried netflix or other services that use it. I have not tried unplugging both ends of the HDMI cable as yet, I guess I will attempt that one tonight. I have unplugged them both from power sources yesterday, but the problem persisted today.
Unplugging the roku and plugging it back in instantly solves the issue for the day.
Can you please provide us the following information:
-Roku device model
(these can all be found in Settings > System > About)
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel (this can be found be selecting the channel on the Home screen and pressing the * button)
-tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times)
-steps to reproduce the issue you are seeing
Once we have this information we will be able to pass it along to the appropriate team to investigate further.
My Roku Express received a new software update yesterday. It did not affect the HDCP problem though. It would be nice if there were a message attached to an update or a web page where one could find out what issues or features an update was intended to address...or is there?
