Hi, I have a Humax Freesat box. Last week an electrician moved the socket on the wall (where I plug the RF cable in) a couple of meters. Since then the only channel I seem to be able to get is BBC2 HD and ITV HD (albeit slightly pixelated). The other channels display the message 'The receiver is not receiving a signal or the signal is too weak'. I have another box upstairs working fine for all channels. This box is linked to the same dish. My question is do you think it's likely that the electrician could have done something that would mean I can now only receive certain channels? Is that possible? Thanks.
