I received a new XB6 in the mail, hooked it up and it was making a buzzing/humming noise. Tech support said the can came lose during shipping and to go exchange it. I exchanged it at the Comcast store for a new XB6(technicolor), hooked it up and the buzzing/humming is louder than the first one.
douglashh, I can ship you a replacement. Please send me a private message with your full name, address, and phone number tied to your residential services for help.
Not here Ken.
