Just recently exchange my DSL because of the left hinge crack. It's a remanufactured unit (refurbished??), anyways, try checking the screens right after, no dead pixel was found, and when I start playing again, the top screen has a green dead pixel for a long while, I was playing bomberman land touch at that time, and then some times later when I switched games, the green dead pixel kind of start blinking and sometimes after no dead pixel is detected. Can the dead pixel be repair by itself, or like self activated by itself, or is this a dead pixel case?? Any one else has the same problem? Thanks!
