Since it seems like a handshake issue, it’s going to be one of 3 things
Bad HDMI port on the box, swap it out
Bad HDMI cord, swap it out

Hi lolalarson, the information that (ComcastAndrew) provided is correct. Try using another HDMI cable if you have one present and let me know if this resolves your issue. A bad port on the box is likely as well but 90% of the time replacing the HDMI cable will do the trick. Please reach back out to me here if you need any additional assistance.

We did not have an intermittent problem once we had a good picture. Our TV would bluescreen from the time we turned it on until we reseated the cable and/or repowered the X1 box.

 

So, not sure if you have the same problem, but this is what fixed it for us:
