It won't bring completely dead (i.e. black) pixels back to life, but it should work if they're just stuck on a particular color. Many tools like this can be found all over the internet, but we could not find a tool with all the functions in one. Therefore, an adequate application was created, called Rizonesoft Pixel Repair.
Before we continue with what you can do with Pixel Repair, let us start with what you cannot do. First of all, you can only attempt to repair stuck pixels and it will not repair dead pixels. Secondly, it will not work every time either. No miracles here boys and girls.
You can use the 'Dead pixel locator' section on 'Pixel Repair' to look for dead or stuck pixels. You can also use this section to help you find dirty little spots and dust when you clean your screen (Because dust does not show on all colors). Now, after you've located stuck pixels, try to repair them with this tool. Set the color mode, press go and place the flashy window thingy under the stuck pixel. Sometimes this unsticks that pixel, but as stated before, not always.
