How do you connect external sound from a tv with no outputs?

Answer 1

Most modern televisions have at least a headphone output so even if there is no dedicated audio line output, the 3.5mm mini jack can be used to take the television output to an amplifier with just a little experimentation with the levels to be used.

If there isn't even a headphone output, the other solution is to take the audio output from the video source itself. Satellite receivers, cable boxes and disc players usually have an audio line output. Each of the sources can be routed to the amplifier and bypass the television altogether. If this solution is chosen, there is a possibility that the audio may not be synchronized to to the vision. This is due to the signal processing that takes place between the video source and the image reaching the display itself. Most digital receivers and players have a menu setting to adjust the audio delay to overcome this. Look for menu selections called "audio sync" or "audio delay". This solution will work for all sources other than the tuners built in to the television. External receivers are the only solution for this.

Note: There are solutions that involve adding wiring to the inside of the television. Televisions have potentially fatal voltages present inside them. Unless you are qualified, do not attempt any solution that involves taking apart any equipment.
