Tony,
I read all 9 posts by 6 people. Naturally, anything is a possibility, and I can't guarantee anything. I do know that if you have a serious problem with it in the first year, we will work to resolve the issue.
That said, I'd rather you enjoy your television instead of wanting to inspect it to wait for something you know would bother you. This seems to primarily be an issue with the A750 (according to that link), so you may want to forgo the DNLA Certified and Content Library in the A750 for the design of the A650 where the problem is less of an issue.
Does anyone here at C|Net:Samsung own an A750 with that issue?
Either set is a great set.

I found a little info on this on the internet. A visit to Abt here in Illinois allowed me to see what the problem looks like. Its not the end of the world, but once you know its there it becomes glaring. Is this an issue that is old and now been resolved?
