Itv, ch4 and all bbc hd channels lost
Since Friday our youview box has been complaining the antenna is unplugged. It is not. The signal has become so poor we are limited to bbc1 or 2 or internet services. A rescan has simply ditched these other main channels. At first we wondered if it was due to snow - but that has gone now. Maybe engineering work - but there is none declared now. We probably receive from Crystal Palace or the Guildford relay. Youview does not allow manual retuning. So what else can I try?
