temporary loss of video and sound when change channels - XFinity

#1
I recently installed a Cisco RNG150N HDMI cable box, connecting to a new Samsung smart TV. When I change channels, the new channel displays for just a couple of seconds and then both the video and audio go dark for 10 to 15 seconds before resuming. How do I fix this?
