Cable tv hookup advise needed
I have a 2019 Thor class c with an external coax hook up for the tvs. I am trying to get the tv's to recognize the cable. I have turned off the antenna booster and am feeding the rv from a comcast cable box. When I run the set-up on the tv and do the channel scan the tv only finds one channel, number 03. I tried change the channel on the set with no luck and also changing the channel with the comcast remote controlling the box with no success.
I know the comcast box works and that the coax cable to the rv is good.
Any suggestions? Thanks
