I also have an LG, maybe a slightly different model, and I do it like this:
I press the gear button on the remote control
At the very bottom I have an icon with three dots (all settings), I click and other icons appear.
There I click on the antenna with the word channels.
After clicking, several options appear, including "Channel tuning and settings", of course we click on this inscription.
After clicking, we again have several options:
Automatic tuning.
Manual tuning.
Program mode.
Signal test.
I click on Program Mode and I have a choice.
Terrestrial TV
Cable TV
Satellite TV
Of course, I click on terrestrial, then on the word manual tuning.
And there I have a choice:
Digital terrestrial TV
Analog terrestrial TV
Of course, we click on digital, a field appears, a board where we can enter and manually select the channel we are interested in.
After selecting a given channel (of course, a single channel), in the lower right corner of my TV I can observe the strength and quality of the channel being broadcast.
When everything is OK, I press: search, add, update, or something similar, but unfortunately I cannot say what exactly because I do not have an antenna connected to the receiver.
The operation should be repeated for each channel separately.
