Many thanks. All channels have failed and succeeded, but the only ones showing the ‘No or bad signal’ notification on screen today are BBC1 HD and BBC HD. ITV HD worked this afternoon, but failed a couple of days ago.
I am one of the ‘older’ brigade, and not excessively knowledgeable on the technical side. Is LNB the arm in front of the dish? Other than recording, a good picture is there through all channels, except as above.
