You need to remove the dome and set the dip switches for DirecTV. You then need to go into the receiver setup menu and select 18" round and multiswitch. Once you have everything right you should be able to power it up and watch TV.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
