We just changed comcast into my name to get a better deal and we did the 600mb internet deal and the 125 plus channel deals and i tried different cords no luck and return boxes with no luck because one tv works very fine one tv 1/2 works but freezes every onces in awhile and you can watch it again then feezes and does it over and over again when watching and the third tv can't get past the welcome screen after doing the self install it says restart and please try again later and plus all the cords are tight and we restarted the boxes from the app and on the website with no luck and we think it make be a cable cord that's messing it up
I have escalated your issue to the Comcast Team available to these forums. Check back often for a reply in this thread from a Comcast Official Employee.
Welcome to the Xfinity Forums. I'm glad you reached out to us here for help with your cable boxes. Freezing is typically due to signaling issues so I'd love to take a closer look and work with you to get those TV's working again. Please send me a private message with your first and last name, as well as your service address so I can assist.
