WOW..... you guys sound smart
The TV is a Samsung I took out of one of our spare bedrooms, maybe 3-5 years old.
The DVD player we purchased last year, a LG cheaper model.
The sound bar came factory installed with the trailer, a Furrion.
I am guessing it is also a receiver since it pays music station as well.
The DVD player is attached to the TV via HDMI and plays as it should.
I have 2 HDMI ports on the TV, and another one similar, but not the same mate.
The sound bar-receiver has a HDMI port on the front of it, nothing is attached to it, nor do I have a HDMI cable running into the cabinet with the 3 RCA cables.
Maybe I can post pictures of it, would that help?
I have a schematic wiring diagram that came with all the other paperwork, but I cannot vouch for is that is the way its hooked up in the rear as its mounted inside a cabinet with no access, other than I guess I would have to remove the front face, or....????
I know I have power, I have radio, I have speaker location ( inside/outside ) so I am guessing they got it right, the issue is I don't know what I'm doing
edit: Also, it has a dome/receiver/directional antenna and 5G something that you can upgrade to. There is a small panel with 2 coaxial outlet connections and an on/off switch that lights up a light when turned on. None of that is attached to the TV, or any other stuff from that location.
