Remove back cover on 60UM7100PLB

Hi, I have a 60UM7100PLB and have taken all screws out to take back off to get inside but it still feels very solid. Is there somewhere on the side or top where there is tabs inside holding together too? If someone knows how to get the cover off this tv please advise me as i have patches of blue on my screen and have some replacement back light strips coming to replace the ones inside my tv. Any help at all is very much appreciated.
