It depends on the game. The missing pixels are barely noticeable in something like Mario’s Tennis where they line up with the black background, but they can always bee seen in something like Wario Land.

It must have been damaged in transit because the system is otherwise like new. It even came with the original receipt. I haven’t noticed any of the symptoms of wear like uneven screen brightness.

Does this apply to my problem? I haven’t been about to find any pictures that look like my missing pixels; they all look like graphical glitches.
