Hello, I had the same issue with my Samsung TV. This is what I did to fix it and for the las 2 month it’s been working ok. 1 replaced the provided Comcast cable with HDMI cable 2.0 / HDCP 2.2 compatible from Amazon or Bestbuy. 2 route the HDMI cable from the XG1v4 box direct to the TV HDMI port #1, if you route it via a sound bar then to the tv it may not work. You can then use another cable from the ARC tv port to the sound system. 3 Allow the box to update at night, I believe Xfinity has been rolling out firmware fixes for individual TV models. This fixed my problem, I no longer have to reboot the box, but this issue is a TV / Topbox hand shake issue it works for some units but not for others. Give it a try and let me know.
