I was watching a recorded programme on my Sky+HD box connected to my LG 60lb580v TV and suddenly the picture froze. This has happened before and the only way to fix it is to unplug the box then reconnect. This time when the box started to come up there was a message on the screen of input not found. I checked the connection and it was all OK. I thought there may be a problem with the hdmi cable, so I replaced it. Still no Sky. Can you help?
