[QUOTE="Archive4, post: 918926"] OK, calling all LNB design experts! Or anyone who has had this problem before Two adjacent houses sharing a 1.8 prime, three in one house, one in another. House with one feed had stupid electrician in who managed to take down the main trip while wiring a ceiling lamp. Power surge / interruption took down the feed to their house, the other three were still working ok, so replaced the lnb for a new quad. ( about 6 months ago ) Yesterday, the air-co unit tripped the mains again ( in the house with the one feed ) and yet again took out port 1 from the quad lnb. As port 3 is not currently in use have switched over to give service. Have suggested they get a decent electrician in to check the earth bonding in both houses to see if either is without an earth connection. Cannot think of any other reason why a simple trip overload could blow the lnb. All help appreciated, conjecture or fact! [/QUOTE]
