Very strange, I've had the SKY+ box for may be a month now. Installed by Sky it's worked very well until I came home to find it locked to a channel. The remote will still work the TV but has no effect on the Sky box. I tried pressing the power button on the front of the box too and nothing. In the end I had to unplug the power from the back and it seems to sort itself out after a while. Took a while to find the channels again. I tend to leave the box switched on most of the time, incase other family members have marked something to be recorded. The fans seem quite noisy too, coming on every hour or so even though it's not doing anything. Is any of this normal behaviour??? Thanks.
