Have you made sure that the input (sometimes referred to as source) matches the one to which you have the Roku stick connected? Please reply here with the serial number/device ID of the affected Roku device as well. It can be found at the back of the stick.
Tried a hard reset holding the reset button for 10-20 seconds. No response and no blinking light.
Factory reset via the reset button requires at least a 30 second button push. Short of that you haven't changed anything.
