I am new to HD and i just bought a 32 inch HD tube. I love it except for one thing, when the screen is 90% black, i get these red and blue dots. If i freeze the screen they stay put, so i dont think its static. When things are playing with a decent amount of color, the dots go away... it really only happens during certain times, and it happens with any of the inputs. If there is no input, it says "no input" and there is no fuz.

any ideas?
