Gamepad Screen Pixelation

Hi all,

So I just got a new Wii U, and everything works great. Only thing is, however, is that I noticed whenever I turn the gamepad off and there's a black screen, on the top left corner I can see pixelation as if the pixels are dead. When the gamepad is turned off though, that corner displays stuff just fine. Is this something to worry about???

ALSO, small thing but the very top off my gamepad screen seems to be bordered by a thin orange line. Might be just overly paranoid?

Thanks!
