  3. Connect the brackets fixed to the TV and the brackets fixed to the wall with a durable, heavy-duty string, and then tie the string tightly. ­ Install the TV near the wall so that it does not fall backward. ­ Connect the string so that the brackets fixed to the wall are at the same height as or lower than the brackets fixed to the TV.
