I have a standard Sly dish with a 4 way LNB on it, however over the last few weeks, I have been getting the message tune failed on 2 of my TVs that I mostly watch. It goes from SNR 99% to tune failed in an instant, then can stay off for seconds, or even a few minutes.
Do these go faulty, is there a way to test them, and are they easy to replace (I can get to it easy enough), if so what is the best option and how...??
THanks All for any help / guidance offered.
