Using USB to update TV with new firmware did the trick for me. Go to http://www.samsung.com/us/support/downloads and go through process to find your exact electronic and then download newest firmware to computer and then transfer to USB. notes: 1) when extracting .zip file onto USB create a new folder, with same name as .zip minus the .zip. Also copy a second version of update to USB, not under a folder. So the USB really has 2 copies. This enabled my TV to find the update when putting USB into TV. 2) on my TV when I tried to go to Support/Software updates, the software update was greyed out. I went down a few options to Remote Management and clicked this, this asked me to agree to something. I just cancelled out of this and then the Software update option was not greyed out anymore. Odd but I did this numerous times and it always ungreyed out Software Update option. Even if your Samsung unit says there are no updates available when trying to do it online, use USB method and the newest firmware (which must be to big to download online (mine was 138 MB)) will solve this really annoying issue.
