Hi
If your getting this message, then it's either:
- the dish has become unalligned from the satellite (in other words, someone / something has knocked it out of position)
- the cable between the box & the LNB ("microphone" in front of the satellite dish) has become lose / disconnected
... most likely, the dish has been moved (happens occasisonally in bad weather).
Check your cables first, to ensure they are connected properly. If they are OK, it's your dish I'm afraid (I am assuming it's the same signal for all)
If you go into the menu's under services, there is an option for checking signal streght ... check this, chances are you'll have no / next to no signal, in which case it's your dish gone off course.
Regards
