Recently I got a 2700A (IR) receiver from my friend as a gift. I have a dish network connection in my home. I connected 2700 A receiver with this dish network antenna and it was working file. Next day I connected back to dish network receiver. When again I connected back to 2700A receiver it is not working. It scans all the channels but I can see any picture. It says "loading nbsp;picture (10%)" nbsp;and it goes till 500%nbsp; and again it start from 10%...........and so on..
Then I checked PANSAT site........and saw an upgrade. so I upgraded to new b75.I got a different menu selection and I thought it was working fine and It scans for all transponders . But when I select the transponder and try to scan the channels, it shows always 0% and I can't see any TV channels or radio channels, even though the quality is over 90 % ; Now what should I do? Can I uninstall the upgrade new b75 to old one.......? I live in PA. or can you send the configuration to test is the receiver is working fine..........? Please help me.
