Hello hello. So I got a 20" iMac. It is fantastic. I pop in the Matrix Reloaded DVD to see how it looked and bam, a pixel stuck green. I remembered reading about the massage and blasting techniques(videos flashing colors). Tried both to no avail. I didn't really pay attention before to know if it was like this or not, but now there is a dark area around the stuck pixel. I notice it during the white boot screen with the Apple and the stock blue background. It isn't really noticeable elsewhere. I will get a picture up as soon as possible but does anyone know what would cause this? FYI: I got this used, so I can't return it or anything. I could only try to get AppleCare to fix it. Thanks for your help.
