Live TV not working (but everything else is) XRE-10007 error

[cjtif]

Recently switched to an new X1 Router and TV box. Everything worked fine... at first. Then the main TV box stopped connecting to live TV about a week ago. I can still record and watch recordings. I can access On Demand and apps (Netflix, etc.). Guide and voice command work. But when I go to a channel I get an XRE-10007 error.  Our 2nd wireless TV box works (will throw up the XRE-10007 error, but I can still get the channel). 

I've checked cables. I've refreshed the system, restarted the box, resarted the router. Multiple times. I have to restart the box from the TV itself--I am unable to connect to restart the box through the website. If I don't get an answer to this question, I will try to call provided a) I can manage to locate Comcast's customer service number, and b) I can find several hours of time to waste.

Hi there, @cjtif, thank you for taking the time to post on our forums. I am sorry to hear the reason for reaching out is due to service issues with your cable services! I appreciate the self-service troubleshooting you have gone through already. Please rest assured, you have come to the right place! I can definitely take a closer look into what is going on with the services or cable box itself. So we can go into a bit more detail, can you send us a private message with your full name and service address.
