First connection to cable and not getting anything. The antenna amplifier switch is off (when it is on I do get a descent air signal). I set the TV to cable as far as I can tell and still nothing. Plan to run the cable through the window to check signal and TV setup this weekend. If that is OK, I will begin to check cable connections. I have a 2012 NT RSDS and very happy with it. Anybody have experience with possible connection locations and access points? Thanks.
