Does the pattern move, or does your "dice" stay in one place?
Also, are you seeing the pixelization on every input, or just the television input?
Do you have a cable/sat box that you could expiriment to see if the issue is fixed by swapping boxes?
Keep me posted.
I have had my Samsung for about 3-4 months now. Recently especially watching hockey games, I'm noticing a blotches on the screen in a pattern similar to a 5 on a dice and then once they are there its on every channel. I have had my tv calibrated as well and it still doesn't help. In addition, now even on low setting automotion, the picture is blurring more than it did the first two months, things that were not pixelized are now.
Please help shed some light on this, I have been a Sony man and went with this samsung based on price (still paid $4k for this TV) but am not having much luck with it.
my connection is running through an HDMI cable as well from an HD Comcast cable box.
Unhappy Samsung Consumer.
