Sky Q issues

[Paul483]

Turned the box on to be greeted with a heavily pixelated screen. Box is working behind the pixelated screen. Tried restarting the box and get the same result. Mini box upstairs works perfectly. 

 An ideas or help would be much appreciated. 
Thanks

hi @Paul483 

probably longshots but worth trying:

A full power down of your TV (i.e. unplug / switch off at mains)

Disconnect your HDMI at both ends & re-seat or try a different HDMI cable
