Swapped our sky box, was working fine on old box, plugged in new box, same exact connections.
Now neither box is getting listings or showing live TV. Red signal light on front of box and under setup, signal test, it shows all <41DBUV and 0DB under quality for all 4 tuners.
Cables seem right and well connected.
I also have a Sky RF box with 35 in LED on it (Might be for sky to show in our kitchen. Tried resetting it.
Output is via HDMI and I can see the Sky Box on the TV, so that part is right. Seems aerial or back.
