Black or red spots appear on the screen. A PDP TV uses a PDP panel consisting of 123million (SD Grade) ~ 315million (HD Grade) pixels. Although a PDP panel is a product that requires high technologies to integrate a few million pixels, a bright or dark pixel may exist on the panel, this does not affect the performance of the product. � Displaying a still picture on the screen may permanently damage the PDP panel. � A boundary may appear due to the difference in the transparency of the panel when watching the picture in the 4:3 aspect ratio for a long time and the picture in the left, right and center screens is a still image. � A boundary may appear when watching a still picture from a DVD player or a video game console on the screen for a long time. Due to the nature of PDP TVs, partial after-images may appear if a still picture is displayed for a certain period of time after connecting a video game console or a computer. This is caused by brightness deterioration due to the storage effect of the panel, and to prevent this from happening, we recommend you reduce 'brightness' and 'contrast'.
