Sony :: Dead Pixel DilemmaVaio Z

I received my Vaio Z21WN/B last week and it is a spectacular laptop. However I was pretty miffed when I found there was a glowing pixel in the middle of the screen.

Upon inspection on a black background I have managed to single out over SEVEN of these pixels, all of them seem white apart from one which is red.

Now the pixels are very hard to see, some more difficult than others and you do have to look for them to find them but it's like anything of this nature, once you know they're there you just go looking for them and they gradually become more annoying each time

I bought the laptop from an eBay seller and really it wasn't his fault for selling this as it was as the unit was sealed and he would not of known this until it was opened. It'd be pretty bad of me to ask for my money back when he was a private seller.

Do you reckon I'm within my right to phone Sony and ask for a replacement screen or should I not bother?

any users on here who have dead pixels on their laptop screen and just put up with them? Is this a widespread problem with most people worldwide or is it just the select minority people such as myself that are bothered about it?
