I have a 40inch Samsung 1080p TV in my bedroom. When I am watching the TV via the built in freeview tuner and using my mobile near the TV, the picture is fine. However, I also have a sky box in the room. When i am watching TV through my Sky box and I get a call, there is interference in the signal, both sound and picture. The sky box is connected to the TV via standard scart cable. It was the same setup when I had my old Pana CRT TV. Please help, this is driving me mad now!
