Fetch TV issue

Hey Guys,

Hoping for some help here.

I decided to replace my old Strong PVR and grabbed a still sealed Fetch TV box off fleabay (1st mistake??)

Anyway i just wanted a better UI and a new toy for watching FTA programmes only - nothing else.

So i did a straight swap with the cables and now im not getting any signal on any channel although I get the station info bar at the bottom of the screen.

When i use the Fetch remote, nothing changes on the screen when i press "menu" etc.

Have i missed something here as i was hoping it was a straight swap to watch terrestrial TV.

Hoping for some input from those in the know.

Thanks Tom
