Hi, My sky+ box been perfect for 3 years and today, noticed my Sky+ box won't come out of standby. Tried pulling out the power cable and putting it back in but no luck. The box responds to the sky remote as the remote green light comes on when i press a button. I've left it with the power cable out now and see what happens in the morning. Any other ideas? When i power it on, the fans spin up, i can hear the HDD access slightly and sounds healthy. What could be wrong?
