I got a Game Boy Micro just recently, and it works great, but there's what appears to be a yellow "glare" spot in the center of the screen. It's only seriously visible when the colors are darker (when the screen goes black, or when opening the start menu in Metroid Zero Mission, for example), other than that, I barely notice it. Any suggestions? I can live with it, but if it's an easy fix (such as dust behind the screen), I'd like to take care of it. One of the screws on the Micro is missing, and another is loose-ish, so it does make sense to me that the previous owner opened it at some point to change the battery or something, and dust got into it. What do you guys think?
