Come home last night after being away and no lights on Sky Q Box, not even red light to say turned off. Unplugged everything over night and tried again this morning, but not working. Red light is on and the blue Q in centre keeps fading on and off. I can't get the box to turn on at all. I've turned all other devices off and just tried Sky, but still not turning on, changed hdmi leads, but still not turning on.
