    I have a bad usb port on my galaxy s4 and was reseating all the connectors and noticed the brown wire that runs along the side under the ribbon cable has copper showing and what appears to be a burn mark on the frame of the housing.

    No, that's not normal. A tiny bit of copper showing (0.1mm, maybe) where a cable goes into a connector is sloppy assembly, but a burn mark means that someone pinched the wire and the insulation got punched through and the wire shorted to ground. That probably did some damage at whichever end of the cable is the voltage source on that wire, like blowing whatever was supplying the voltage.
