My stupid mistake

Black Hole

May contain traces of nut
So sorry not to be an expert. That's the reason for me being here........
We don't expect you to be an expert, just to report accurately:
p.s. I don't know if Humax aerial power is on or off, and as I can get no image at all, I can't get to the menu
This would not have been the case. The Humax menus would have been available on the TV screen via HDMI, even without a UHF feed.
