So apparently a line of dead pixels falls under the category of physical damage and is not covered by warranty according to Nintendo. They wanted me to pay $80 for the repair, which is ridiculous considering the console is not even three weeks old and is in pristine physical condition. The CS service insisted that the console had to have been dropped for the black line to show up, but like I said, the console is in pristine condition and was never dropped/hit or anything like that. It hasn't even been played 10 times yet. After a bit of back and forth with CS, I was able to get the fee dropped for the repair. "But we can only do it this one time", like I am the one at fault here and they are doing me some kind of big favor.....hahaha. Definitely a frustrating experience, but the right thing was done in the end.
