Bear with me it is my first post. :Jump:
I and probably quite a few others have stuck pixels and may or may not have the means to load a homebrew application onto their DS. I had a pink dot stuck on my touch screen and it was annoying me slightly so I read a couple of guides on the internet and tried their suggestions to no avail. I just loaded up Dr Kawashima's Brain Training (Name may vary in other countries) went to daily training, loaded up my account, went to Other Options and went to Change Signature. Now if you are lucky your stuck or dead pixel will be in said box to draw your new signature if it is erase your current signature and scribble around and on the dead or stuck pixel so it is covered in black fictional ink then reaptedly scribble over roughly where you think the dead pixel is. It took me about ten seconds but after a while stop just dont erase it power down your DS and switch it back on and hopefully your Dead\Stuck pixel will be gone.
I'm not responsible for any damage caused to your console but Im sure nothing will happen.
