Hello
You need a universal controller positioned for direct current (usually 5 volts) and go up there to disconnect the F plug and measure between the central wire or "Core" and the metallic plug on the outer side; there is a way to measure (if the needle seems stuck to the left below zero, reverse the measuring leads). If it's a device with a digital display, there's no problem with direct reading since it's automatic polarity. Now you can also measure the output of the decoder at the bottom; it's less dangerous, but you're well advanced because if there’s power, it means the fault is elsewhere, and if there’s no voltage on the F plug at the output of the decoder, two things to check: look at the setup menu of the demodulator to see if you have correctly activated the "power the LNB" function; otherwise, there’s still no voltage, and your decoder is faulty. You’ll have to get it repaired after checking that your cable to the satellite dish is not short-circuited (a clip through the cable or poorly made F plug where the shielding wires (outer braid) touch the central wire). This is troubleshooting; anything can happen.
Good luck searching and especially good courage.

Thanks again.
But if, for example, as in my case, I have a CANALSAT HORIZONS decoder, how can I find out?
