Determine if I have a Bad LNB?

[Blastineous]

Good day to all,

My Slimline 5-LNB dish and H-21-100 receiver (at the cabin) has worked flawlessly for 4 years. I installed it myself, and am comfortable with this process. Suddenly, I've lost a handful of HD channels. Up I go on the ladder with a Signal Meter to tweak the alignment, and it only needs minor adjusting, but still the handful of HD channels are missing. My gut says the LNB is bad, but before I go changing it I'd like to confirm my suspicions.

Satellites 101, 119 and 110 show normal signal levels (90's - 100)
Satellite 99(c) shows 90's.
Satellite 99(s) reads as follows: 0 66 0 70 0 70 NA-->14 0 0 82 80 0 0 90 95 0 0 NA-->END
Satellite 103(s) reads 0 89 0 95 NA-->14 0 91 0 0 0 95 0 1 0 96 NA-->END
Satellite 103(ca) reads 0 83 0 86 0 83 0 87 0 87 0 86 0 89 0 91 NA-->END
Satellite 103(cb) reads 0 92 0 90 0 89 0 88 0 89 0 88 0 91 NA-->END

I did not check every HD channel, but the following ones are confirmed MIA:
229, 231, 241, 248, 276, 277, 290, 307, 340, 365 and 535.

What can I do to get the system back to 100% functionality? Questions? Comments? Queries? Posers? Thoughts & Ramblings

Thanks in advance,

?B

Check all of the connections first. You likely have a bad cable or connection somewhere.
