Got a problem with my zgemma box, it keeps losing sat signal but I know due to plugging another box in that the signal is definitely there, I've brought up the signal finder and it says 0% signal on both tuners, it done it the other day I left it off for a while then turned it back on a hey presto it was back! Has anyone else had this problem and how to fix it cos the box will be going out the window very soon!!!lol
