Most TVs have a menu setting that says internal or external speakers.Here are the instructions for yours.

Turning off the built-in speakers Use this feature to turn the TV speakers off when you connect an
audio system (see "Connecting an audio system" on page 11).
To turn off the built-in speakers:
1. Press MENU, then press x or • until AUDIO menu appears.
2. Press y or z to highlight SPEAKERS.
3. Press x or • to highlight OFF.

some tv's have a button on the back that will turn on or off the built in speaker system so that the tv can be plugged into an external system and allow the user to use the tv's volume control for the ext. speakers without hearing the internal ones, if there is no such button check the tv's setup menu for a setting that enables or disables the speakers

LG 60PK550 only outputs the audio via the optical out port on the back of the TV the HDMI ports don't have arc capabilities

Depending on the model TV, there may be a switch on the back to turn the speakers off, or there may a choice on the audio on-screen menu to turn them off. Not all sets allow you to turn the speakers off, but you can always mute the sound, although this sometimes leaves the word "MUTE" on the screen to remind you. You can also just turn the volume all the way down on the TV. If you're using the AV inputs on the TV with a device like a DVD player, another option is to connect the video only to the TV, and feed the audio to the amplifier providing surround sound. Then the TV speakers won't be used at all.

You have the center sound on in your menu, just turn off the cneter sound option and it will all come back on

It sounds like the headphone jack may be going bad. I do not know how to replace it, but if you can find BN94-01208C fits LNT1953HX all you have to do is swap out the main pcb with the new and you have a working tv agin.

My 37 inch vizio did the same thing. go to your menu screen on the tv and go sound. My tv has an option to turn speakers on/off. Once I turned my speakers off and the back on again everything worked great. hope I helped! if I did please let me know! youtube.com/xniax1
