I have Wharfedale 1710AF connected to a Sky digibox and the TV keeps blacking out and going into standby mode. I have tried connecting it via just scart or just aerial lead from the sky box but either way it keeps turning off. If I connect 2 TV's at the same time to the sky box only the Wharfedale knocks off. If I move the wharfedale to another room and connect it to a Freeview aerial it stays on. The only thing I can think is that in the original room the BT Home Hub is doing something to the TV. The wireless channel used on the home hub is 1 but if I change it to say 7 the TV keeps knocking off. I've had the same Sky digibox for years so assume that can't be the problem. Any ideas?
