How to get your Sky Box to start turning on again after a power cut

  1. Unplug your Sky box and leave it turned off for 5 minutes.
  2. Hold down the BACK UP button on the front of your Sky Box.
  3. Power on the Sky Box from the mains while still holding the BACK UP button down.
  4. You need to wait for software download screen to appear and then you can release the BACKUP button.

This method will work for some people but will not be an option if your receiver refuses to power up.

What to do if this doesn’t work

If the above method has not worked then you will likely need to perform a planner rebuild. Alternatively, we can always arrange an engineer visit for you.

A Planner Rebuild is a better option to go for to save your stored recordings and settings.

  • Firstly, press the Services button.
  • Choose option 4 – System Setup.
  • Now press the 0, 1 and Select buttons on your Sky remote control.
  • This should take you to the Installer Setup menu.
  • Now choose option 7 – Sky Planner Rebuild.
  • Select Sky Planner Rebuild and wait until the system message ‘Housekeeping please wait’ has gone and the system has restarted.

The last resort to get your Sky Box up and running

If you choose to complete a factory reset, all of your recordings, series links and reminders will be deleted in the system reset so check these things first:

  • Check if the box is in standby mode.
  • Is the box connected to the telephone line?
  • Is the box and its wiring connected and switched on at the mains?
  • Check that your Sky box software is up to date.
  • Is there sufficient signal? Are you experiencing bad weather?
  • Is the Sky viewing card fully inserted?

Again, all of your recordings, series links, and reminders will be deleted so proceed with caution.

  • Click the Services button on your remote.
  • Press 001 on your remote then select.
  • This will take you to the setup window.
  • Click across to system reset and select.
  • Finally, a ‘For your information’ box will appear and display ‘Housekeeping please wait’ the box will now reset and reboot.
  • This will now complete a planner rebuild and factory resets your box.
  • The box will be wiped like new.
