Why will my Samsung QN43Q6DR TV not pair with my Sony WH-1000XM3 BT He

I’ve tried several times to pair my new headphones with my new TV to no avail. Followed all the steps but the TV will not recognize that the headphones are even present. Anyone have an idea what the problem is? TV recognizes my IPhone so I know the BT works. (Headphones selected above are incorrect but was all that was available to allow me to ask the question.)
