My iPhone has some white/yellow/blue lines when turning on or unlocking, and some white/black faded lines across the screen with some text. Is this a screen issue, or something worse? And either way, what parts will I need to fix?
@invoxiplaygames sounds like a bad display. Post some images of what your screen shows with your question so we can see what you see. Use this guide Adding images to an existing question for that. Ultimately you do want to start of by replacing the display. Use this guide for that.
