I have exactly the same issues as above. My tuner A will not pick up anything at all, but as soon as put the same cable into tuner B this finds a signal straight away.
I have just replaced a Skybox F5s which worked fine and when swapped tested back to old equipment still works no issue.
I have installed Zgemma star 2s Vix 3.2.021 sucmnsee full! Backup 02.12.2015 and set up exactly as the guide suggests. I have re-ended the cables even though know they work fine.
So my issue is any ideas for getting tuner A working set up exactly as tuner B. The only way to get the box to work is to disable tuner A but can not download the cross EPG without errors.The scan found 110 channels but no SD channels all HD.
Would appreciate any help...
How's the signal strength from your dish?
signal strength is fine because i have tried another box and abm is working on that
