All of a sudden my samsung digital tv, well, i get a picture but there's no sound. The picture is as clear as it should be, because it looks like snow. Those little white dots on it, i can get a picture but no sound because of those little white dots and sometimes it turns black and white. The tv is only two years old! please help, what could be wrong, i'm wondering if its the cable box, i use comcast.
