My Roku Premiere went completely dead this morning, alternating between a black screen and the kind of gray screen you would see if you disconnected an antenna from your TV back in the day. I hadn't gone anywhere near it so was confused. I did a little googling and found this simple fix that I was able to use with the Android phone app:
"Press the Home Button Five Times
Press the home button on your Roku remote five times.
Press the Up Arrow Once
Press the up arrow button once.
Press Rewind Twice
Press the rewind button twice.
Press Fast-Forward Twice
Press the fast-forward button twice. Then wait for a few seconds and your Roku device should restart."
It started to work even before I got to the last step. It did some kind of restart and after playing with it a little and trying the steps again it's working as normal.
Thought I would share.
