Just got my replacement earlier today and noticed one stuck pixel like the first device I had. I was reading Jscreen's website, and it says to run their fix early in the life of your product with an LCD screen. So since it just turned on out of the box today, I have been running it over and over at 20min intervals. That red pixel seems to be fading slowly, which to me is awesome news.
Also the other key is shutting off the screen and letting it cool down after running this. At least the website says to do so, with anything with an LCD.
