I bought Apple TV yesterday. The extisting TV had only one HDMI connection so I swapped it with a TV from another room which had two. MySky is plugged into one HDMI port and the Apple TV is plugged into the other. Both Apple TV and Sky work fine. I have a feed to various televisions in the house which displays the channel that is being viewed on the main TV. I receive this on an Analogue channel. This is working fine also. When I tested the digital TV reception, I had lost it on all TVs in the house. I did not touch any wiring except for unplugging the Sky HDMI connection, the AV1 connection to my DVD player and another plug which has one white and one red plug that was plugged into sockets under my HDMI connection on the old TV. the DVD works fine, so it must be the red and white plug that have sent things astray. I have tried them in various sockets in the back of the new TV and have had no luck. Does anyone have any advice on how I might fix this? A picture is attached of the connections prior to me moving the old TV. Thanks!
