Yes Sky is fine... I have used the TV remote to cycle thru the various external inputs to see if I can see the picture thru any of the AV 1,2 3 etc
Sky is not directly connected to the AV receiver.. It is connected via HDMI to the TV with an optical connection to the receiver for sound...
The cable between TV and receiver I now won't be able to recheck until the morning.. Sorry
Fixed this myself... Dodgy HDMI cable.. thanks anyway..
