XG1v4 4k DVR no signal to TV blue screen

Works fine until I switch HDMI input to other source like Xbox or Blu-ray then when I switch back to XG1v4 the TV displays a blue screen. I have to manually disconnect the HDMI cable from the back of the XG1v4 and plug it back in to watch my TV shows. I believe this is being caused by a failed HDCP "handshake" between the XG1v4 and my Samsung KS8500. Since this started happening only after upgrading from the old X1 DVR to the new XG1v4, I have to blame the newest component. I read another post on blue screen issues and laughed when the "service expert" suggested a short with the TV. Please don't insult me like that. And yes, I've already disconnected power and coaxial cable and waited 5 minutes and reconnected and It still does it. I swapped HDMI cords to a high quality cable, and tried different HDMI inputs on the TV. I don't think I should have to "trick" the XG1v4 to re-establish signal with my TV by pulling the HDMI cable every time it blue screens.

What's the solution?

I just went to Expert Settings on my Samsung TV and turned off CEC. I’ll monitor to see if there is a reoccurrence of the Blue Screen and report back. 

Great thread by the way.
