Thanks for stopping by. We have two Freeview boxes in our flat; one in the sitting room and one in the bedroom. I don't know much about aerial cables and wiring (which you probably will understand), but there is a socket marked "SAT" in the sitting room from which there is a coaxial cable with a two-way splitter, one end going straight into another socket marked "TV" and the other end going via an RF cable to the Freeview box. This is how our landlord had installed it. In the bedroom there is another socket marked "TV", into which we've put an RF cable leading to the second Freeview box. This has worked fine for about a month. Now all of sudden when we turn on the "main" Freeview box (the one in the sitting room) that particular channel AND any other channel on that frequency won't work on the other box. The instant we change channels on the main Freeview box the channel reappears on the other box but then the current channel on the main box won't work on the second box. We must have done something wrong with the wiring, but I don't really understand why it's worked fine until now. Has this happened to anyone else here, or does anyone know what to do? Thanks in advance for any help.
