Question on stuck pixels

[sg2386]

I bought a Samsung LN40B540 LCD about a week ago from Costco. Not really an LCD person since i have 2 plasmas but decided to buy an LCD for my bedroom. It's been great so far, but noticed recently that there is a green stuck pixel. I can't see it but found out by fluke when the screen was black and i went to check out my DVD player, was kind of bummed about it.

Was thinking of exchanging it, but it is a pretty big hassle packing it up and taking it back to Costco and who knows, maybe the replacement will be worse.

I tried those software programs to try to fix but never worked and i don't want to try those pressure or tapping methods to avoid further damage.

If i do try to exchange it what are the odds of the replacement having a stuck or dead pixel? and is it really worth the hassle and effort trying to exchange it?

I have 90 days to return or exchange, so still trying to debate, but it's always going to be on the back of my mind when watching movies that there is a green pixel that will likely drive me crazy.
