No audio output

Not sure exactly which kind of extractor need or best way to create an audio output on a LG 28lj430-pu tv.

That model number TV doesn't come up online.
If the TV doesn't have any audio output at all then it is possible to connect a speaker to line level converter to the wires that the internal TVs are connected. That will give you an analog audio output.
