I have a 2017 BH 3575EL with a 55" Insignia tv and have a problem. I'm at a campground that provides free cable tv but I need to hook up a cable tv digital adapter and this requires me to run a HDMI cable from the adapter to my tv and I can't get to the HDMI port on my tv without unbolting the tv from the wall. Am I missing something? There has to be a better way.
