I've received two screens from DealExtreme. The first screen had a huge clump of dead pixels so I got a replacement. However, upon installing and testing both screens, I noticed that the top screen is immensely darker than the bottom screen. Can anyone explain why this is happening? Any help would be appreciated, thanks. First Screen With the Dead Pixel Clump: Screen Replacement: So far, I've soldered on the speakers, they work perfectly, but the screen is still dark.
