The gf moved into a new flat with a satellite. I hooked up her cheap dse freeview box and it worked fine for a week.

At some point it stopped working for no apparent reason. Now it just says no signal, optus d1, 12483.

I have no experience with freeview, is there anything easy I can try to fix it?

(It seems to be the satellite, but my idea was to try and borrow another freeview box before getting someone in to check the satellite..)
