Hi @Katie1966 and @Davey791 Rebooting the puck will often resolve the technical fault message. You can either unplug the puck for a few minutes and then plug it in again and the puck will reboot. Alternatively go to Settings > System Management > Resets & Updates > Restart device.
With either method the puck will take a couple of minutes to reboot during which time you will have a blank screen until the Sky logo appears.
