Re: Blue Dot
Well, I wouldn't call it a "dead" pixel, but it's kind of stuck. This occasionally happens to LCD monitors and displays. Sometimes, a stuck pixel will fix itself, though sometimes it will stay like that indefinitely. I don't know if bumps have any effect on the pixel or not. My advice is to ignore it - because I doubt the store would give you a new one because of a pixel, but if they will, go for it.
But I say again, it's not a dead pixel. It's simply stuck. My DSLite has one green pixel on it. My brother's DS use to have a bright blue pixel, however, it fixed itself and works fine now.
Happiness is not about being perfect.
It is about seeing beyond the imperfections.
