TV guide works on main box but not on other two smaller boxes.

Try rebooting your boxes

That is a common message. The guide should finally fill in within a few hours. Don't worry about it.

It's been like that for days not hours. 

[pgm1961]

already did that.

It does smell like a software issue.   Maybe temporarily swap a small box with the big box and see if the problem moves or changes?    Tighten all the connections leading to the small boxes?   Any degradation noticeable with picture on the small boxes?

We have been having the same issue for days. We only have 1 set top box non X1 service and have rebooted the box. We also randomly get the message “your set top box is not authorized for service” with a blue screen of death which then rights itself within a few minutes.

I heard it was a signal strength issue with everyone stuck at home.   Sounds reasonable.  Ours has come back but it took days not hours.  We'll see how long it lasts.  Our audio cuts in and out sometimes as well.
