2.2GHz 15 inch mid 2007 Macbook Pro. I seem to have some image burn in the top right corner of my LCD. It looks like a blurry Spotlight icon, the "PM" from my clock, and so on for about 2 inches. It's not that bad, I can only notice it when there is a bright solid colour in the top corner of my screen (when the menu bar isn't visible.) Anybody experienced this before? My laptop is on a fair bit, but my screen saver is set to go on after 15 minutes. There have been a few times when I have run my laptop overnight without allowing it to go to the screensaver or sleep, and I've simply turned off the backlight until the following morning. Could this have been a cause? I wouldn't have expected it from a modern LCD which is generally treated very well.
