When I first bought my DSlite about a month ago, it was just fine. No stuck or dead pixels, it was perfect. But just last night, one showed up on the top screen of my DSlite! I'm pretty sure I remember hearing about some piece of homebrew that will clear up any stuck pixels but I'm not sure what to even look for! Can anyone help me out here? On another note, what causes stuck pixels? Any way I could avoid more in the future? Thanks for any help.
