I have a 42"inch Olaf & Ludwig plasma display i have been using for just over 3 years. I have had this problem for a while but am wondering if it is anything i should be looking at fixing. My plasma display has a snowy effect in dark areas of a picture/movie. When my son watches his cartoon channels like Cartoon Network and Nickelodeon the snow effect isn't there as these channels mainly have bright pictures, but if i put on a movie or watch a movie on DSTV then I get this snowy effect mainly in the dark areas of the picture/movie. Is this something i can fix or this something i should expect to live with.
