Program information missing on one TV

How is the TV Receiver that is not properly displaying the guide information connected to the U-verse Gateway?  Coax, Ethernet or Wireless?

Both of the slave DVR's are on wireless.  One is working and one is not.

There's some terminology problems here that may be adding to the confusion (at least to me).   There is only one dvr wired to the gateway.  The wireless boxes are just wireless receivers.  So @skeeterintexas question remains; have you rebooted the dvr, (pulled plug for 15 secs.) not the wireless receivers?  From your original post you appear to be referring to the wireless receivers as "slave dvrs" (no such thing but that's your terminology) which you said you rebooted.  You have said nothing about rebooting the actual dvr.  Usually rebooting the dvr fixes these kind of grid display problems which is why it was initially suggested.

Yes I have rebooted the DVR for the TV that is not showing the information, and nothing changed.

Thanks, that did the trick.  I have been rebooting the DVR that is attached to the TV that did not have the program information, and nothing changed, but I followed your suggestion and rebooted the DVR attached to the gateway with Ethernet, and that fixed the problem. 

You have one DVR.  The other 'boxes' are called Set Top Boxes (STBs).  Those can be wireless.  The DVR is wired directly to the modem or Residential Gateway (RG).
