I have sat dish set up for astra 19.2 and 28. Now all I get on screen is the station name followed by "no signal". no matter what station I want. . I cannot see any breaks in cable and connections seem ok. I have 2 seperate LNBs, 1 for uk stations (19.2) and 1 for continental etc. Any suggestions? The set up is ca. 9 years working perfectly.
