If your TV provides power through the HDMI port, then all you should have to do is remove the stick, and then your Roku will be turned off. If your HDMI port does not provide power, you would have needed to connect a micro-USB cable adapter to the Roku Stick and have plugged it into a wall outlet. No matter what the case, as long as you remove the Roku Streaming Stick directly from the HDMI port, the Roku will shut off completely, learn more at: http://www. manualslib. com/manual/696105/Roku-Streaming-Stick. html.
