I recently installed the X1 DVR box to it via HDMI cable and noticed that during use the TV randomly powers off or changed component source (HDMI 1 to HDMI 2). I also find that the TV is powering on by itself overnight. I've disabled/turned off the Anynet HDMI-CEC function on the TV but issue still exists.
would you check your comcast labs setting for "HDMI Link" and ensure it is off? (press Xfinity button >> gear(settings) >> Comcast Labs.
