What causes LNB to fail?

A fault in the voltage switching either in the Sky Digibox or (more commonly) the LNB can cause some Sky channels to fail with a “no satellite signal is being received” message. Intermittent faults can also occur, which can cause picture freezing, pixelation or signal break up on one polarization or the other.

Can LNB work without a dish?

The LNBH works without the dish. The function of the dish is to collect and direct a low signal into a strong signal and the LNBH helps as part of the dish to deliver a watchable signal to your receiver . All the parts of the dish work on their own in its own way.

How long should an LNB last?

Yes it is, though you’re assuming the LNB is in use 24/7. If you were to use a figure of 14 hours of use per day (0900 – 2300) it’s a lifetime of just over 714 days, or a bit less than two years.
