[QUOTE="Old Fred, post: 26336"] But the "Panafix filter" thing supplied by a certain mail-order company connects next to the tuner and as far as I can tell it has no effect on the DC supplies. Against my better judgement, I volunteered to fit one for a neighbour who can't solder. I checked with my ancient oscilloscope and it seemed to be damping down an oscillation in the LNB cable, which was displayed as pulses around 1kHz in frequency! The power supply outputs were "clean" in this one. Anyway, it's easy to tell if it's the classic Panasonic fault. When the "no satellite signal.." appears, carefully disconnect the LNB connection at the back of the receiver for just a moment then reconnect it. If the picture appears (takes about 15 seconds so give it time) then this filter thing should fix the fault. If you prefer to climb ladders, rather than solder 3 wires, then a different LNB might cure the symptom, if not the cause. Fred [/QUOTE]
