Yeah, I might try to take it back after this weekend; I forgot the box somewhere (It's in a safe place). I bought it at Zellers, by the way. I always keep my receipts, so I shouldn't have that much of a problem taking it back. Would it be ironic if I took it back to the store for a replacement, and my replacement had more dead/stuck pixels?
It's a really annoying stuck pixel, about 2cm down and 2cm right from the top left corner. It's green or blue on a grey background, and it stands out in some games more than others.
One store that I know would replace something in an instant would be Walmart. I've had a replacement for my Gameshark SP that wouldn't boot up and I took it back without the box or instructions. This was about four years ago. I've even been given a refund for something when I didn't have the receipt.
