I have a sky Q box with a Samsung Bu800 tv which up until today had worked fine. Having turned on the TV today the SkyQ input is completely blurry, mainly just green lines across the screen both on live tv and the menu. I've tried all resulting settings but these just changed the colour/look of the blurry tv rather than remove it. Ive also tried different HDMI cables, different HDMI ports but still doesn't work. Have also done a full factory rest on the sky q box and upgraded to the latest Q220 software to no avail. The issue is not with the Samsung tv screen as this works fine on its main screen and with other devices plugged in
