Hi. ( sorry My English ) I have a Samsung Plasma PS50C7000, more and less two years. At the time I made all those desirable processes in plasmas, from the Settings download up to take pictures of those colors to go with burning the pixels (I think this is the foundation). I ran all during all those hours counseling (200Hrs. not mistaken). And while I do some retention of channel logos, but nothing unusual because until then disappeared, I now notice a problem much worse and that bothers a lot. When I see an image is on film, novel, television news ... that "target" scenario the picture is dark and dull, like it's another to overlap ... well this may not be the end. The image is not Clear. This in dark images, the images with light is not perceptible. This is "normal" in plasmas? Example 1... Correct image with very light ... Not dark image: Example 2... With dark image: Thank for help and sorry My bad English.
