Most of the time, Nintendo is spot-on with their hardware fixes. Send your system in for repair and they take great care of you and the system itself. Unfortunately, that wasn't the case with one gamer's Wii U GamePad. He sent it in for a dead pixel and dust in the screen, but got it back like this.
Some bleeding edge issues that get worse with more color, plus screw hole covers weren't really given much love. It's clear that whoever took this GamePad apart to fix it ended up making things worse!
