I think I may have a dead pixel in my MBP. I've got the October 2008 model, the LED display. Today I noticed a little grey-ish speck in the display. And trust me, it is IN it, not ON it. Believe me, I wouldn't be wasting anyone's time if this was something that could simply be cleaned off. It is not visible when the display is off; when that area is dark, the spot is visible as a lighter grey as compared to the surrounding area; when that area is white/light, it appears as a darker grey color compared to the surrounding color. Having said all that, I have still cleaned the screen thoroughly several times but to no avail. It is visible from the boot screen (white screen with the apple) and as long as the screen is on, but again it disappears when I turn it off. From all this, I gather that it is likely a dead pixel. I have reset the PRAM and of course that didn't help. I called Apple and they agreed with me, so I went ahead and set up an appointment for the Genius Bar (almost an hour away ). The whole point of this is to ask if anyone out there has any ideas of other things I can try to get rid of this problem short of the Genius Bar (obviously I'm hoping it's not a hardware problem). If anyone has any suggestions as to what else the problem may be or anything else I can try to avoid going to the Genius Bar, I will be eternally grateful. Thanks in advance for any help.
