Okay, I've had quite the experience with 3DSes over this past year. I thought it was all over just a while ago, but life can never be that fair.
Back in March I got a Pikachu 3DS XL, which I was severely disappointed by due to a plethora of problems (severely wobbly screen, scratchy sound, got dirty inside the screen very easily). I sent it to Nintendo Repair multiple times in order to get these problems fixed, but because it was a limited edition they couldn't do anything without replacing the system. Every time I sent it in, I would transfer the data to my original 3DS so I could continue playing games in the meantime. I eventually tried some home maintenance, which ended up bricking the dang thing. So today, I got the Zelda 3DS XL, and was surprised to immediately realize it was of much higher quality - screen doesn't wobble at all, sound is always perfect quality, and the system overall feels all smooth and sleek and not like the cheap piece of plastic the Pikachu edition did. Very satisfied, I'm sure to, as I do with every device, look for dead pixels - even though I've never had one before, I'm aware of them and just want to be certain. Scrutinizing the screen very carefully, I determine there are none, and then I perform the system transfer from my old 3DS to this new one.
Now, once the transfer is completed, the first thing I want to do is see how nice games would look on it. Being a Zelda system, and because I think it's the game with the best 3D effects, I appropriately put in Ocarina of Time and try that. Everything looks great... until, while wandering Hyrule field, I notice a black pixel just above Link. No matter what I do or what changes on screen, that black pixel remains. I go to the home menu, and the dark aura surrounding the game's logo, while very black-ish itself, still noticeably has a pitch black pixel in that spot. It seems to only be visible under certain conditions, hence why I didn't notice it prior to the transfer - when the screen is bright or white, the pixel does not stand out at all. Yet, when put against other, darker colors, it's a very visible black splotch on an otherwise perfect screen.
In short, I have a dead pixel on the system. I want to fix it, but I do not want to return the system, since it has all of my data and I'm out of transfers (not to mention that even if I could transfer it, I'd have to wait a week, at which point the Zelda XLs will most definitely be sold out everywhere), and I do NOT want to send it into Nintendo because all they ever want to do is replace it. Has anybody here had a similar experience with a dead pixel they were able to fix, and if so, how? I've heard using certain GIFs that flash tons of colors and pressing down onto the area the dead pixel's in, but so far neither of these have worked (I do understand that the color one is supposed to take some time, though, and I only did it for about half-an-hour). I would like to hear from someone who has fixed this problem though, not speculation or "what you've heard." Any real help is greatly appreciated, thanks!
