I have ariza 700. I am getting no signal. I have done factory flash, loaded bin 2.81 then 2.91 then 2.93 but none worked, it still shows 28% level and 0% quality & when I scan , it fails. I have tried another box and it worked fine, so I believe cables and dish are ok. Could it be a hardware problem or software ? P.S: If I shake coax cable a little bit, level goes upto 45% but quality still 0% and scan still fails. please any suggestions ?
