I don't think there is anything wrong with Nintendo's qc, I believe there is a certain rate of tolerance for these parts and a stuck pixel or two out of a thousand or two is considered acceptable in the terms of quality control, now I'm not saying you should live with it as a user, take it back if you're not happy, but from a technical standpoint, I bet you there is a certain failure rate considered acceptable and these units ship with the stuck pixels. My two cents anyway.
