My Samsung TV displays black and white all the time, on any source cable, tv, etc. I tried plugging in my dvd player or any game consel same problem. Picture quality is perfect but only displays black and white. For sometime i heard what sounded like spinning disk, i dont know if these tv's are equipped with a color wheel??? Please help. Thank you.
If your TV is a rear projection DLP TV is does have a color wheel which could certainly have failed. I would check the color setting in the TV to make sure it is not all the way down which would give you black and white on all sources.
