I recently purchased a samsung lcd tv and have noticed an issue with "screen tear". Every now and then, about 3 inches from the bottom of the screen, the screen will get a line that flickers across the screen (screen tear). Ive dealt with this issue before with playing xbox 360 games, however those were because of the game, not the tv I was using (a toshiba hd tube). This "tear" always appears in the same spot and happens in movies and other misc. programs. Is this something common with lcd tv's or might I have an defective tv? I also noticed last night while watching Disneys Dinosaurs on dvd through my xbox 360 an occasional, extremly quick "flash" where the entire screen had a slight tint of green. This has only happend while I was watching dinosaurs. Any Ideas?
