Stuck Pixels and dead pixels are annoying. Unfortunately, Sony doesn’t provide support to fix Stuck or Dead pixel issues. If you are frustrated with such a problem then here’s a quick solution that you can try out.
I came across a Stuck pixel fixer developed by a guy on PSP-vault. So how does it work? It continuously flashes Green, Blue & Red colors on the screen to fix any stuck pixels.http://www.dailymotion.com/video/xaaj34
Here’s what the developer has to say:
It has worked around 60% of the time. I tried it on my friends, that had 6 stuck pixels, and it fixed them all. The only real thing you can do is set the video to repeat and leave it on for a few hours. In version 2.0, I have added a white screen and a black screen, so you can periodically check to see if your pixels have been fixed. Good Luck with it to all of you.
