Lost channel/ feed in other rooms

Hope I explain this right

Telly in sitting room has all the Irish channels via saorview / external aerial .
I have a free to air box connected which gives me the uk channels / sky news etc .

2 TVs in other rooms were picking up the satellite box channel ( couldn’t change channel in the other rooms when watching , but was handy to lie in bed watching sky news etc)

Hadn’t bothered turning the other 2 TVs on lately until today and the satellite feed is gone .
2 Samsung TVs , done an auto scan on both , no sign of them picking up the satellite feed , but picking up all the Irish channels no problem .

The tv in sitting room working fine and picking up the free to air no problem .

Any idea what could be wrong ? Checked the splitter box in attic , all connected fine from what I can see .

Thanks a lot for any pointers .
