Hello, I no longer have a signal on my TV, I have a voltage of 12.5v at the end of the coaxial cable on the satellite dish side with 2 LNBs aimed at Astra and Hotbird. It worked well until now, except in bad weather. My question is, how can I check if the LNBs are not defective? Thank you for your help.

    Hello,

    13V vertical polarization, 18V horizontal polarization
    As Contrariness says, these voltages are sent by the demo depending on the transponder requested with its polarity.
    It will cost you more to have it tested than to replace it given the price
