External speakers connect

Solution
Since the TV doesn't have any audio outputs you would have to open the TV and access the wires going to the internal speakers.
You could extend the wires and connect passive speakers but the TV may not have enough power. If not then you would need a speaker to line level converter that would give you way to connect powered speakers or an amplifier and passive speakers. Not electrically complicated, You do need to get inside the TV.
