XG1v4-A

There have been no error messages or warnings. The screen shifts to snow with a band of color bars across the bottom and right side.  This lasts for about 15 seconds and then there is a complete loss of signal.  Power off and then on resets the box and all is well for a few days. I have not used the troubleshooting as the methods seem to address normal issues

Okay, in that case I would like to take a closer look at your equipment on our end and see if there are any changes we can make remotely to help out. Firstly, can you please send us a direct message with your full name and complete service address?

Here's the detailed steps to direct message us:
• Click "Sign In" if necessary
• Click the "Peer to peer chat" icon (upper right corner of this page)
• Click the "New message" (pencil and paper) icon
• Type "Xfinity Support" in the to line and select "Xfinity Support" from the drop-down list
• Type your message in the text area near the bottom of the window
• Press Enter to send your message. 
 

Thanks.  I waited until the unit failed again this evening and then contacted Xfinity support.  A new unit is being shipped to me.  I will follow-up once I have the new box in service.  Below is the screen.

Good evening and we wish you well! Out team wanted to connect with you and see if you had received anything in the mail? 

I have received the replacement unit and installed it.  This morning it exhibited the identical failure mode.  Clearly, there is something else causing the periodic failure of this model of converter box.  The previous models did not have a similar issue.
