Hey, found a great program (i think it was on digg?), basically just generates alot of random colors to bring your dead pixels back to life. While I have run the program to see if it works (it does), I havent had any dead pixels to test it on, let me know how it works!
EDIT: I keep getting a message saying I am not permitted to upload a file with that extension, I tried uploading the standalone file, Jscreenfix.jnlp, and then I tried putting that in a .dmg file and uploading that, no luck. This program is very small (4kb), Id be glad to forward it to someone who knows where to host it.
