Do you get all channels if you take the aerial out of the box and plug it into the TV?
I assume you have got the aerial (a terrestrial freeview one) plugged into the box? Hopefully a silly question!
If so go to settings, home button then up arrow and select the cog wheel, and try a factory reset which will reset the box and download the software again.
Let us know how you get on.
