Thought Problem Was Fixed???

Just got my new 27inch iMac today after the shipping was delayed 2 weeks and I thought the reason was to fix some of the problems they were having with it and now after about 2 hours I get a screen flicker about every 3 minutes or so, its not flickering on and off(yet) but just an annoying quick flash. Anyone with same experience or advice?

Call up apple and they will either replace it or fix it for you. The problems haven't been resolved completetly but there have been a lot less machines with the problems. It seems you got unlucky. Hopefully it won't take to long for them to fix/replace it.
