I've recently bought a os mini single sat tuner for a spare room. in another room I have two feeds going into living room & two upstairs (4 feeds from LNB). in the upstairs room with the 2 feeds. i have taken one cable and taken over to the spare room, I had to buy a RG6 Satellite cable extension to reach (came already fitted with the F connecter and joining barrel).

the issue I get on the os mini is tuner lock, aslo on the other box upstairs (vu zero) if the os mini is switched on, the channels break up (plays for second and goes to black screen with no picture). if I switch the os mini off the other box (vu zero) works fine. but no picture on the OS mini.

I know it not a single issues. am missing something. do I need to swop the cables around? I hope not, as I 've pinned the cable to wall.
