I just turned on my brand-new and long-awaited Mac Mini and 20" Cinema display to find a big black dead pixel square in the middle of the screen (like, opening a Finder window in the default position has it between the first two icons. I'm so bummed I just turned the whole thing off and am typing this on my old G3 iBook. (There's another dead pixel lower on the screen, but for some reason it doesn't stand out as much). I did a quick google and found what appears to be an oft-cited Think Secret claim: Is this true? Has anyone had success in a similar situation? I bought my setup from the online store because I had a BTO Mini; can I deal with a retail store on this issue or must it be taken up by phone? Any tips on how to get the best resolution to this problem? I really don't mind dead pixels in general -- I understand why they happen -- but this one is truly unacceptable (a word that came to mind even before I found the TS article!). EDIT: see below for how this turned out. Last night I took it to the retail Store (was going to the Plaza anyway), and it turns out that it was either A) A clump of 5 or 6 contiguous pixels, all bad, which the head genius said was the biggest defect he'd ever seen, or B) A piece of debris from the manufacturing process that got stuck between the two pieces of glass. Either way, they were nicer than nice about it and swapped it out for a new one for no charge and an apologized, too. The best part? I got home a hooked up the new one, and there are zero dead pixels. I am, quite possibly, in heaven.
