My Lg uh615a smart tv does not have bluetooth or wireless for bluetooth earphones what do i need to use bluetooth earphones

Depends which wireless headphones you have. Most headphones do not use WiFi, they use Bluetooth or 2.4 MHz RF. Usually a wireless headphone set will have a transmitter plus the headphones. The transmitter usually connects to the TV either with the analog L+R ouputs or the stereo headphone jack.

Is it a "smart TV," meaning that it has BlueTooth capability?

How to Add Bluetooth Headphones to Your HDTV

Through the 3.5mm headphone jack from your headphones, its a pretty small hole usually to the front of the tv set, being so small you may have to look for it. If it is wireless you will need to connect the main headphone system to the back of your TV (audio in jack) then ensure system is powered on and headphones are charged.

If your soundbar has bluetooth technology in it, turn it to the input of "Bluetooth" or "BT". In your TV's smart menu, you should be able to find bluetooth settings, and be able to find the soundbar from there. If you are looking to connect it by a cable, you will have to connect a digital optical cable into the back of the TV, and run it down into the soundbar to receive sound out of it.

Unpair and re-pair with your phone.

Your wireless headphones work with input from the audio output to the device base. Connect this unit accordingly with the power for the unit. switch on the tv and set your headphones to the desired frequency to lock on. Hope you get this right. good day

First try '0000' (four zeros). If it doesn't work, switch to '1234'. It it keeps failing, try '8888'.
Hope one of these codes might suit your case.
