The water sensor in the port of my phone is a light shade of pink and Apple won't replace it. It hasn't been NEAR water at all. I need to place my phone because I have a few lines of dead pixels covering up the middle of the screen. The genius bar told me it is unlikely that any water damage caused the grey bars but my warranty isn't valid because of the miniscule water damage. I swear on all that is holy that this phone has never been near water. Any ideas on how to fix it? I could really use the help before my screen goes completely grey! Thanks.
