Purchased new 52" Samsung hdtv in 2007 it is getting to when watching it, the top half will go grey then black out, the bottom is still on. It is on HD cable box and screen that was once very clear now looks like red, green and blue glitter dancing in back ground, you have to be close to screen to see this.
The HDTV has a heat-related problem check your fans. Do they remove heat? the vertical chips paint the screen from top to middle and, middle to bottom so; your top to middle vertical chip is overheating as is your video chip; that is why you have "glitter" in the back ground. get rid of the heat or, bye,bye TV.
