Hello,I am Pete, and I'll be happy to assist with your question today.
When do you get the "No signal" message - is it only when you try to view TV channels?
Yes, the payment covers me to reply back and forth as often as necessary to get this problem resolved for you.
The box isn't getting a TV signal from your aerial.
Have you checked the aerial connections at the rear of the box?
Try removing and reconnecting the two aerial connections (this box has a twin tuner) and then try again.
If it still won't work, test the aerial cable with a different TV to ensure it is still working.
If you are using an outdoor aerial, check that it hasn't moved or fallen over.
Let me know what you find?
