Help! My brand new Xfinity X1 bo makes a whirring sound all the time, even when the TV is off. Is this normal, or do I need to trade it in? If so, how do I do that?
I have same issue with new TV box I picked up yesterday. I can hear it 30 feet away in another room.
I also lost Internet connection during setup. It doesn’t seem to me it would be related to the box, however it’s a hellava coincidence.
bad hard drive or cooling fan bearing. swap it out.
