Thanks to all, they are going to ring Faults again tomorrow. They are quite happy atm as they have one of my Samsung boxes that works perfectly but I can imagine they would be really unhappy if they had just been sat looking at a blank screen all weekend

Does anyone know of what the difference is between the Samsung and Pace as to why one will work and not the other ??
I know the levels are right because I took all the readings myself (just what I wanted to do after a days slog as well

) in my house and theirs
