Recently purchased a Philips 7072 digital satellite receiver/decoder. Using it with an Attisat (square) satellite dish. Signalstrength is good, have activated my subscription to CanalDigital and receive all channels. Problem is that after a variable length of time, sometimes seconds, sometimes minutes, the picture dissappears and the receiver shuts itself down and then goes into standby mode. Upon switching on the receiver, the same happens... channels are ok for some seconds or minutes and the receiver switches of again. If I remove the RF/Coax cable, the receiver does not switch itself off. Purchased the receiver in Holland, Purchased the satellite dish in Norway and am viewing in Norway. Anyone have any suggestions as to why the receiver may be switching itself off ???
