Going through some old posts, and thought I would update this one. I bought this TV from Amazon warehouse deals for $750. I contacted amazon, and they refunded me $200 to keep it, rather than ship it back. As I said the bars were barley noticeable, and for 550 I could live with it. Then I thought about it a few days later and called Samsung. I gave them the serial # and they sent someone out to fix it as it was under warranty.
