I have a DX and noticed today a red pixel at the bottom of the screen that only shows up in dark places. Like the settings menu and what not. If the screen is bright (like shades of white/gray) it doesn't show. Other places it's red.
My initial thought was it was a dead pixel, but searing around other users said it was stuck. That sometimes you can get it unstuck.
Is that true? Or is the only way to fix it replacing it?
