What do I do to get new cable box??

derelict Thank you for reaching out to us here with your questions! If your existing X1 box is not 4K then you can definitely exchange the X1 box you have for a 4K box at your nearest Xfinity store. I am sorry to hear the Xfinity store you used to go to has closed, you can find the closest Xfinity store to you by going to the following link https://www.xfinity.com/local/store-offers. If you would like us to send the new box out by mail (there may be a shipping charge) I would be happy to help, just send us a Modmail message, so we can get the process started!
