About 2 years ago, I was transporting my computer over to a little lan event and I took a corner a little too hard. As a result, my 19" Sony CPD-G420S took a dive off the seat of my van and wedged itself between the seat and the door. After quietly muttering a few explicit words, I stopped and put the monitor back in place. Ever since then, my screen is blurry in the upper-left corner whenever the brightness goes up (i.e. dynamic display mode) - any ideas on how to fix this? It's not so blurry as to be unuseable, but it's annoying because my screen use to be ultra-sharp no matter what it was displaying.
