1.) All those coils pictured look normal---coils have what looks like a burn mark on them naturally. 2.) Before any work is done on a coil or backlight diode, you have to first make sure that the backlight filters are intact---this is the most commonly damaged component after water exposure in any iPhone. If the filters are blown, you'll never get a backlight.
