I have a new LGLD320 TV and Sennheiser headphones. With my old Hitachi TV, I could plug in the headphones without stopping the sound output from the TV. With the new TV, it goes mute. Is there any simple way of restoring (independent) output from headphones and TV ?
Contacting the manufacturer service desk - no help
There is usually a little switch behind the headphone jack that do that automatically. It's a convenience for most but an inconvenience for when someone not hearing well need the headphone while others in the room don't. You can get this bypassed at a TV repair shop. Another solution is to use the optical audio out on the back of the TV as the audio source for the headphone. That require a converter to analog plus a small amplifier (or you can use a sound receiver with optical sound input and it's own headphone jack included).
If my TV doesn't have the little switch that's 'usually' behind the headphone jack, I shall have to try the alternative optical audio option. Where do I get the necessary converter and amplifier, or a sound receiver with a headphone jack ?
You can get a converter at this link. This output a line level analog signal, your local electronic store should have little booster in stock to convert this to something able to drive a headphone. As for a sound receiver, you might get that for not that much if you look for used system, even an old 5.1 system will do as long as it have optical input and a headphone jack on the front (you don't even need the speakers usually coming with it).Another possibility is if you have a cable or satellite box, sometime those have analog audio out and would just need a small booster and an adapter for the headphone 3.5mm connector.
