Would not recommend

I purchased this TV, it has a great picture; however I realized the picture was bowed..it was smiling at me as one of the other reviewers posted. I immediately exchanged it for another. The second one still has the bow, however very slight, and my wife said I was being too critical (I can be annal at times). 2 days go by and I am now experiencing a buzzing sound from the speakers whenever there is bass. I have never turned the volume past 60%; however it sounds like it has a blown speaker. I suspect it is the case/frame that is buzzing against the speaker, but I am not sure. It appears Samsung did not test the final product. I am going to return this TV, and I would not recommend it.
