I have a 56 Samsung 5687w I beleive. Anyway returned 1 already due to the black bars on the side of the TV not being staright. I'ts like they bend out on top and bottom. Very annoying to look at. Just got my second set today and it does the same thing. I guess they need to send someone out here to work on it or should I just ask for another TV untill I get the right one? Is this just a fixable convergence issue? I only notice it on the side bars when watching digital channels.
