I had a power cut the other day and when power came back on the freeview had the "No signal" message on the screen.
I have reset the box, left it unpluged looked at differnt settings on line and still no luck. I have tested the freeview at another house and it worked.
I have now ended up finding a way to change the frequency from 12483 to 12488 and that gave me the TVNZ channels.
any ideas what I can do?
