Dead Pixels on Lumia 820 screen

[mland550]

I recently bought a Lumia 820 from eBay - it was new in box and never used. After charging it and setting everything up I decided (after fighting myself for a bit) to check for dead pixels. Unfortunately, I found about seven of them, some are in the lower middle and the rest are scattered off to the sides. This is an AT&T branded handset, and when I took it into the store they wouldn't exchange it because it had not originally been purchased from them. Do I have any recourse in trying to get them to replace it? Does Nokia have a minimum number of dead pixels before they consider it defective?

Thanks for any advice!

What color are the pixels in question? Dead pixels are black, Stuck pixels are any other color.

They're black - they appear unlit on solid-colored backgrounds including red, blue, yellow and white.

I'd give Nokia a call.

Can you go outside (Where the sun are shining) and see if it's actually DUST under the screen? Just to make sure.. I also have speck of dust under my screen, which I thought was dead pixels at first. They look almost similar.
