Sorry to hear about this. Have you tried a factory reset: http://www.samsung.com/us/support/supportOwnersHowToGuidePopup.do?howto_guide_seq=6790&prd_ia_cd=N0000058&map_seq=98610
I just bought a brand new UN60ES8000 two days ago, when I was watching in movie mode there were some flash on the screen, I decided to update the tv with the last firmware. Everything went good but since I did it i got some problems. Sometimes the image jump, the tv Freeze and reboot itself, sometimes when I try to enter in a menu with the remote or sometimes just watching the tv.
