Sony AW190 custom built - problems! Need help.

OK. I've just received my fully loaded AW190 and... noticed a couple of problems:

1) Screen flickers every 5-10 seconds. Very slight but noticeable flicker
2) Dead pixel
3) Spot/stain on the screen that cannot be removed. It's the size of about 5 pixels. These are not stuck/dead pixels.

RGB LED screen.

I need your advice. I can:

1) Purchase next business day coverage and call them to have someone replace the screen. ~500USD + I think the policy is "to the maximum cost of the computer". So if to replace the screen costs $700, I will be left with only so much for future problems. Worth it?
2) Bring it to the service center and have the screen replaced. I doubt they will replace it with a refurbished screen, but there's a chance. Also... the feeling of not having a "brand new system"
3) Send it back to Sony, get a refund, place another system and wait for it to be delivered. ~3 weeks total.

What would you do?

I wish Sony had Dell's customer service. Complete care policy for $300 CAD covered the computer COMPLETELY for 3 years with next business day on-site service. It also wasn't to the maximum cost of the computer, so I did not have to worry about breaking the computer/etc.

Thanks for any advice. What a disappointed to get the top of the line system with a screen problem.

Thanks for the answer.

Yes, #3 sounds good although it's a pain to send back/etc. I like #2 as well since they can order the screen from Sony and then replace it while I wait...
