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 I use any LNB on my dish?
There are lots of different types of “universal LNB” and contrary to as it sounds not all LNB’s are universal with all satellite dishes.

The first thing to check on your coax cable is that you have good continuity in the center conductor from one end of the cable to the other. To test this, touch one probe from your multimeter to the center conductor on one end of the cable, and the other probe to the center conductor at the opposite end of the cable.
Does a dirty satellite dish affect reception?
Not typically. Satellite dishes are built to be outside, so they can handle a buildup of dirt, pollen and remnants of where birds may have used the dish as a perch. A clean vs. dirty dish may boost curb appeal, but it will likely have little impact on your signal quality.

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.
Why does my satellite dish have no signal?
This issue is usually a result of the satellite dish being in a slightly wrong position, damaged or malfunctioning equipment, severe weather, or something blocking the dish’s view of the sky.
