    I have 2 sat boxes connected to quad lnb
    When I disconnect the cable from the upstairs box the signal disappears on the downstairs box.
    Any ideas?

    (1) Faulty LNB

    (2) If 'Outer ' of satellite co-ax cable to downstairs box is a poor connection somewhere: Note The Co-ax, as well as signal carries DC current from box to power the LNB. (inner positive, outer negative) . Despite a bad 'outer' connection the DC circuit is being indirectly completed somehow to downstairs (terrestrial aerial cable from a common point to both TV locations probably)

    LNB power turned off in the downstairs box,

    I'm pretty sure cables are ok
    Lnb power set to polarisation

    If the downstairs box lnb power was off, it wouldn't have been receiving a signal, no matter about the upstairs one.

    The 4 lnb outputs are powered independently, or should be anyway. Must be some kind of electrical fault, like Antenna mentioned.
