Remote not working - XFinity

Got a new box for my basement TV in order to receive HD, not working at all.

"All power" light flashes when hitting buttons showing it is powered. Does not do a thing, won't change channels/volume, nothing.
Box itself set up nicely, has a channel coming in but obviously it is stuck on that.

Any suggestions before I trudge back to comcast for an exchange ?

Attached are pics of the remote and box
