So, my Nintendo DSi has developed a stuck pixel in the upper-right corner of the bottom screen. This sort of thing really irks me, so I set about searching for a way to fix it. Of course, I’ve bumped into stuck/dead pixels before, and in my experience, once they appear, they’re about impossible to get rid of without replacing the screen altogether. And, manufacturers are usually not happy to do this for free for just one bad pixel, even if the device is under warranty.
