Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.
Initially, let's try check and review the basics. Proposed preliminary tries (if have not been done) check the two (2) cables connecting the Digital Media receiver to the Display unit. Of particular interest would be the pins of each plug. Ensure that all pins are present, straight and evenly spaced.
Additionally, check and ensure that the "...satellite receiver..." is set for max 1080i video output resolution.
