Samsung LN40A650 40-Inch 1080p 120Hz LCD HDTV with RED Touch of Color Immediately

I am very happy with my purchase of the Samsung LN40A650 TV from Amazon. Ceva trucking called 4 days after my order to arrange for delivery earlier than the 13 days projected. I took delivery 7 days after shipment. The Ceva driver set up the TV and was competent.
The TV has a great picture with the the factory settings. Numerous adjustments can be made. The sound comes out from the bottom of the TV and is only fair.
I am surprised by the warning on the inside cover of the manual. It states "A still image may cause permanent damage to the TV screen". This includes black "bars" on the sides of the screen when the picture being received is smaller than the screen. The TV does not automatically resize to fully fit the screen when on a HD (700) channel and the broadcast is in standard format. The manual states that damages caused by "screen burn" are not covered by the warranty. I have never heard that LCD TVs could have a screen burn problem, only plasma TVs. I called Samsung twice. One Samsung agent repeated the manual warning. The other said don't worry about it.
