Just bought a new 42" Plasma. calibrated it with the DVE DVD and I'm not sure whats going on. While watching Hi-Def programming and it goes to a night scene or anything real black the picture gets like a weird tint almost like a gray picture where it should be black. Is this a faulty plasma or is the blacks real bad on this model? Everything else looks great just any Blacks get a real funky look to it almost like a grey pixelaztion to it.
