During a recent gale my 80 cm analogue dish with Nokia Universal LNB became damaged. I have since acquired an older 80cm dish with LNB ( no marking on case ). I can find Astra 19.2E with an older Cambridge decoder however when I connect dish to Nokia 800 SRD Analogue decoder all prestored channels e.g. Sky News, BBC radio etc.. have disappeared. Is there some system settings which need to be reset for older LNB or do I need to tune all signals in again? Any advice would be much appreciated.
