* UPDATE *
We went out today. First we tried unplugging all HDMI's and Ethernet (per Brent's suggestion), still no IR working. Unplugged for 10 minutes, still a no go. Then we replaced the IR sensor on the TV with Samsung part. Still had no IR response!!
So, set it up for IP control via URC TC system. After set up it's working fine via IP control. I'm a little worried if the Samsung loses the "token" between URC.
How's your experience with Samsung's via IP? Ever lose it's connection?
I'm still wondering if I have any other options to try and make the IR work again......
