Hi, I hve had my Pace sky+ box for just over a week now and it is making a rather irritating high pitch 'chirping' noise. The noise happens irrespective of whether the unit is switched on or on standby, so I dont think it is the hard drive. It is not a loud noise (in fact it is only just audible from the viewing position), but if you are watching a quiet program (snooker) or are in the room when not watching TV you can hear and is becoming annoying. Interestingly, if you take out the signal feed to input 1 the noise changes so it cound be related to the digital tuner. Is this normal, or should I send the box back? If it is normal, are there any suggestions as to quieten the thing as I dont think I want to live with this noise long term. Thanks in advance.
