Can one feed from a Quad LNB go faulty?

    I have a Sky dish and Quad LNB (older type not Sky-Q modern type) and the SkyHD in the living room is working fine off its two feeds however the Freesat TV in the bedroom has lost signal.

    I tried it also with a FTA satellite box and that can't find signal either. I'm going to get some cable and extend the Sky cable from living room to bedroom TV to test just incase it might be the TV, but with FTA box and Freesat TV both not getting a signal I'm inclined to blame the LNB. Tv TV is 11 years old and a 50 inch so it isn't so mobile hence extending the cable instead of moving the tv.

    I keep thinking that wouldn't the LNB just totally give up or can one feed just die like this?

    Yes, one feed can die.

    Have you easy access to the LNB to swap the cables around there instead of running new bits of cable?

    Yes have seen this happen with a combination of water ingress on the F-Connector and it becoming loose, I redid the connection to the cable and taped up, was fine after.

    It could be the cable at fault rather than the LNB.

    I'll have a go at it over the coming days, 2 feeds going to the SkyHD box are fine, this 3rd feed to the Freesat tv is faulty and the fourth feed is ran into the attic and held in reserve and connected to nothing, hopefully I can swap them around and that will solve the problem if it is the problem.
