Hello. I just got xfinity service a few weeks ago. My main room tv, wireless xfi box, has a light on that is continuously flashing. Also, the "Welcome.." screen is frozen on the tv and has been for a few hours now. I have other tv's that work perfectly fine, along with my Wifi. The remote won't let me turn any channel or anything, just turn off the tv. I have unplugged everything, restarted all the systems with no luck. Any help would be appreciated.
