A 2023 should have KeyTV. It's a module that feeds and splits all signals. It's typically located in the wet bay. Check to see if it has power. The blue light should be on. This is a common problem. If it has power then remove it and check all of the connections. If it doesn't have power there is a fuse somewhere. I'm not sure of it's location. Maybe someone here knows. It might be behind the unit. You should also remove all of the wall plates and check those connections as well.
