Hello, we splashed out on an Oyster 5 to get TV abroad expecting it to be foolproof (we are totally non technical). We are in Spain near Gandia using a Carthago Alphatronics tv. The dish seems to lock on to Astra 2 (pressed the tick when it comes up as told) but tv seems to be totally scrambled - one of us has messed it up, not saying who! Just into a 9 week holiday so would like to sort it. Any ideas please?
