Unplug your Sky Q box from the mains and wait 30 seconds. Unplug all cables and your viewing card. Plug it all back in and go through the boot up process. If this doesn't work you may need to call for a refresh signal. 150 if you have Sky Mobile or Talk or the number under "Need more help" on this page - Sky Help | Sky.com
