I have an MS9 in my Astro City that is in great shape overall with no burn, except for a dark spot left over from some tape residue that I had removed. The previous owner had left some tape on the monitor while it was in storage, and after I brought it home I scraped it off with some windex and goo gone. There is no more tape residue on the surface, but I noticed there is a dark spot on the tube where the tape was, I assume it somehow reacted with the top layer of the tube while it was in storage. Any advice for fixing this or am I out of luck? It almost looks similar to burn, but not as noticeable when the screen is on. I've attached some photos of what I'm talking about.
