Pretty much figured that as my next option. Trouble is, don't have that as an access option until the 23rd. Oh woe, no TV till then. The thing I find a bit puzzling is that clearly something is coming thru the LNB, because, if I disconnect it Signal Strength disappears altogether. Re-connect and it leaps to 70%. Signal Quality flutters around 0-1%. Is it just that the LNB has drifted "off channel" as has been suggested? I have tried shifting the TP freq up and down by incrememnts to no avail. ?????????
That will just be the noise that the LNB outputs along with the signal.
Is it still working at all at some times? If it is then try changing it by a MHz up and down at that time and see what the signal quality does either way. Keep going till it starts to drop off again and leave it there and see if it helps with the loss of signal.
The other option is to go and buy a STB from a place with a good return policy and take it back if it also fails on your dish.
Thanks for the input. No, not working at all at any time. You gotta believe this, too. STBs are so cheap I was gonna just buy another one and what the heck. There isn't one to be bought for miles. Everyone, literally everyone is out of stock! By the time I get this solved it'll be time to go back home. :-( I think I'll buy a satellite finder and a LNB to bring back next trip and in the meantime take this STB home and check it against our existing installation there. Looking more and more like no TV for the duration of the holiday :-(
