I did tons of research before buying this TV. Everyone recommended Sony. Well, I have had two TV's delivered and I have returned two TV's within a week. The first never turned on, flat out did not work. The second has a display/menu that flickers and randomly blacks out. Sony has no explanation for the black-out and told me to have it serviced. There is no way I am serving a TV that is a week old. Has any had or heard of similar problems? I am now looking into the Hitachi 51F510. Anyone have comments on that?
