de_lasoul,
i doubt samsung will swap, most prolly will just repair it. the shop swapped for me.

bro,
u mounted it urself!? u my hero la. haha.. the installers installed for me. two of them. saw them struggling coz of the weight man..
but accidents do happen

. anyway i think u shld call the shop and tell them the prob. i didn't prove much to them, after telling my sales agent the prob, he said he will reserve a new set for me.
showed the guy who came a few of those stuck pixels (darn difficult to see and find), he looked puzzled and just swapped.
i did ask him if anyone has swapped for this matter, he said sheepishly - ur the first one.

i'm rather particular i guess.
anyway they swapped with a new set. checked in service screen.
