Hi DJDJ,
Please be sure that your TV's legs are on correctly "R" on the right. "L" on the left. The legs will slant outwards towards the edges of the TV. When the legs are inserted into the correct holes in the proper direction, you will hear a "click" when they are inserted in all the way. If you have concerns regarding your setup, please contact us at 1-800-SAMSUNG, 8 AM – 12 AM EST, 7 days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/
