I have recently got the 42" Panny 6, and have got a slight problem with the display of blacks and some other dark colours. There appear to be small moving white dots in the black areas. This is noticable from my watching distance (about 12 feet), when large areas of black are displayed, but only from close distances when the areas are smaller. This happens both on DVD connected via component, and Freeview connected by SCART. Has anyone else experienced this?
