In my old house, the aerial went to the living room, the satellite also to the living room, then a coax from living room to loft, a booster in loft, and down to each bedroom.
So we could watch in the bedroom what ever we were watching in the living room, this worked OK in the days of 14" TV's in the bedroom, but as we started to use 28" TV's it was simply not good enough, and we moved to skyQ and the wireless system they offer.
So it may be that the wall outlets have not been used for years. The booster/splitter may be missing, or the power supply to any mast head amplifier missing, or simply you are trying to use a terrestrial TV to view satellite signals.
To get satellite in each room, will need an LNB on the satellite dish with multi-outlets, and not all LNB's are the same, I have a hybrid, so two outputs are for SkyQ and four go to free-to-view (not freeveiw) set bottom boxes.
Our main living room TV should work with satellite, however it will only show half the channels it should, I would assume the TV is outputting the wrong voltage, the LNB switches between vertical and horizontal polarisation depending on voltage, so will guess TV is not switching the LNB as it should.
But of all our TV's only one can receive satellite, all the others need a set bottom box, have you ever used the TV's on satellite before? Some of our boxes will show signal strength to help aim the dish, and my son-in-law has his dish aimed at a Turkish satellite, so is the dish facing the same direction as others in the street?
