I got a new Bush 21" CRT TV and for some reason when watching a DVD through RGB scart or even RF, when bright white lights appear on the screen or even a bright white image, the TV seems to react to it, almost following it with a wave of dark contrast. Similiarly, when you watch it, in general it's ok, but when watching a show, as the camera angles change from a well lit shot, to a slightly less well lit shot, the contrast appears to visibly change. I am wondering if this is a damaged model and should I bring it back?. I remember a topic like this coming up before where people had trouble with white light or images on their screens but, if I remember correctly, it was with older sets, this one is brand new and i'm sure it should'nt be like this. Any comments?.
