I am having the same problem with my Pace D430N digibox Model 1.0.55
Version 9F0A01
O/S 1.2S4FM
EPG Ver 3.8.8
No contract bought outright despite having the Auto standby disabled, is switching off so my recordings in the night just show a blank screen & No Signal.when switched on the message says telephone connection required (I thought this was only needed for Sky+)
The box is also doing this during normal viewing
I emailed Sky and this is the part of the reply relating to my FTA problem

If you have a standard Sky Box please follow the connection check process below:
Set your box to standby by pressing the on/off button on the top of your remote control. A red light should now appear on the front of your box
Unplug your box from the power supply and there should now be no lights on the front of your box
Check all cables going into your box to make sure they are in securely. Pay particular attention to the cable that screws into the "Dish input" socket, as this is the cable from the dish that carries the signal
If all connections are securely in place, plug your box back in to the power supply. At this point the red light on the digibox should be on. Allow your box to remain like this for 2 minutes
Now press the Sky button on your remote to switch your box on. The red light should now be green and your box should now be on information channel 998
You can now check your other channels to ensure that this has rectified the problem
If this procedure has not been successful, then the problem would most likely be with either the Cabling or the Dish
If after following this procedure you are still experiencing problems, you may need to contact our Technical team for further assistance. If you require a service call and your box is in warranty, this will be free of charge. However, if your warranty has expired, the service call will be chargeable.
I hope this information has helped with your enquiry. If you require any further assistance, you can respond to my email. You can also contact our Technical team on 08442 41 14 11, where one of our advisors will be happy to help.
