Channels breaking up - new LNB?

[tony_i]

I noticed last night that I have having troubling with (I think) some particular transponders - mainly SSports but my local BBC1 is also poor.

This is through a Zgemma but it's also the same using the satellite tuner inside my TV upstairs.

It has to be something to do with the dish side of things.

I'm thinking of replacing the LNB. Is it likely to be the problem? Are they known to fail?

I would guess the dish has moved a fraction......what signal rate are you getting ?

[tony_i]

0% on some, 90% on others. I've just ordered a sat finder.

If I find out that the dish is okay then it's definitely the LNB, and I'm sure the signal finder will come in handy again at some point.

All sorted, courtesy of a ?10 signal finder from Amazon. Lowest signal strength is high-60s now.
