I have an LG 43LF540V which has extremely limited connectivity I have a Humax HDR 2000T connected to it for recording purposes. My problem is I want to use some Bluetooth headphones with this TV, I know I need a transmitter to achieve this (ordered) but always thought there was an optical option on the TV but there isn't. This is the transmitter and TV connections in Pic. How do I get this transmitter hooked up ? do I need some other kind of cable/converter - optical to RCA. Are those RCA sockets the right ones ? Is it possible to plug the transmitter into the Humax optical port ? Sorry if these are lame Q's but thought this was going to be easier than it is proving because of the limits of the TV connections.
