Hello John!
To use the Vodafone TV remote to power on and off your TV you first need to pair it following the instructions in the welcome guide that came with the box. In summary, the instructions are:
Pair your remote control with your TV by pressing and hold the Yellow + OK button. After the Power button blinked green twice, press and hold the Power button until your TV turns OFF. Release the button immediately. The Power button will start blinking green until your remote control is paired. This can take a few seconds up to 5 min. Afterwards your Vodafone remote controls volume, power and input source on your TV.
Hope this helps.
