We just switched out or boxes. Connected the living room box (the bigger of the two) and it works fine. Switched the master bedroom box and no matter what I do, I get the RDK-03036 error in the bottom right corner of the screen. I've re-tightened the cables and re-started the both the bedroom and living room boxes. Living room works fine ... bedroom box always ends up with the RDK-03036 error.
Any clues on how to resolve this?
