HDMI not working, only get channels on COAX. - XFinity

#1
I finally got my channels to work today, but only with the coax hooked up. It will not stream thru the hdmi. The cable is fine, it will send a signal from my laptop to the tv. I see others have had this issue, but I am unable to see how it is fixed. Yes I do change the input to HDMI, so that isn't the issue.
