Gah!! My tv in our living room just developed a horizontal black line directly in the center of the screen. So lame!
Try tapping the screen. If that doesn't work, burn this iso and play it on dvd repeat through the night with your television on. http://www.eaprogramming.com/ (click downloads, then left hand side... iso) This is basically what's on the dvd http://www.youtube.com/watch?v=6GwrHzjgFtw bunch of colors used to stop image retention (at slower transitions than the YT video) This is I used to break in my plasma. It can help in fixing pixels, too, because it works to reheat pixels.... sort of like how 16:9 black bar areas on tvs can get dead pixels from not being used.
