It's perhaps either a combo Saorview and Free Sat box, or the home have a centralised distribution system. Connections on the back would confirm. Do you have a make/model of the box?
Did it only stop working recently?
Assuming all channels are accessed the same way via that box, then you can rule out the TV as the issue. So it's either a problem with the box, the signal being received by the box, or a distribution system if one is in place.
Any other residents with the same setup and same issue?
