Hello all. Please help me. My LG Flatron W2486L LED LCD Monitor has recently developed a whitish patch near the lower center part of the screen. I don't know how or why this has happened nor do I know what it is. I haven't dropped the monitor or dropped anything on the monitor nor opened it up. It just appeared all of a sudden. I am attaching pics of the patch. Does anyone know what this is and if possible, how to fix it? Many thanks!
