I have an old Sky dish on the side of my house that i feed into the bedroom TV.  It's been going fine for the past 4 years but over the past month I notice that there is digital noise in the form of  breakup bars on the screen every second of so.  I've check the wiring at both ends and it's OK.  Turned  of the STB for a day   to see it it is a thermal problem bit it's still there when powered on.
Would I be correct and assume that the LNB is on it's way out??
PS.  The dish hasn't moved .

That's what I was getting ... got worse and worse over time.   Fitted new LNB all is perfect again.

Might pay to double check this if you can, as even a few mm of movement can destroy your signal. High wind, or the ground settling (particularly Canterbury) can do this without it being obvious. Having said that. the most probable cause is failing LNB
