For anyone who has this issue I wish you luck. I have tried a total of 4 different hdmi cables, 1 media streamer, 4 bluray players and 2 dvd players and all have the same issue. The tv knows the player thru the hdmi, shows the very first screen identifying the manufacturer, then refuses to handshake with the setup screen. I tried using rca cables on the dvd player and I do get the screens but when you play the dvd with hdmi all I get is a pink screen and can hear the audio. I bought a Roku unit and it works with rca cables but not hdmi. I'm getting peeved. The picture is excellent otherwise.
One thing I am absolutely positive about is this is the LG tv and has nothing to do with any of these players.
