Having the same problem as 3nearfall". No useable info at Samsung site. Should have dumped it back in the box except it is the size I need. As a regular LED TV it would be acceptable. However the frustration occurs when the menus needed to set up as a home TV are greyed-out and not accessible. Just wanted to let you know that some of these "Hospitality" TVs are being sold by "reputable" internet distributors for home use to naive purchasers.
