Need headphone solution for Panasonic c12lcd tv

It sounds like you have wireless headphones so maybe its not tv maybe more like transmitter signal between headphones and reciever so hopefully you have a way to test siganal. However the default headphone jack on TV should work fine unless turned off in audio settings in TV. Hope some of this helps you.

Contact any service technician. The headphone socket might need to be replaced.

The only way to do it (unless you go inside the TV and modify the TV) is to use a small headphone amplifier (or powered PC speaker system with out headphone jack) and connect it to the AUDIO line out (Red and White RCA jacks) on the back of the TV.

That is normal operating mode when using the headphone jack. The only way for you to do this without cutting the sound from the speaker so you can hear the sound (if your remote headphone has the Line level input), is to use the audio line out (WHITE and RED RCA jacks) to feed the remote headphone unit.
What the make and model of the remote Headphone system that you have?

Most TVs these days do not come with headphone out jacks. If your TV has RCA audio out, you can get a RCA to Headphone jack.

If your TV has no audio outputs at all, you're out of luck.

If your TV is equipped with audio out, there will be an option in the speaker or sound menu of your tv to turn off internal speakers and transmit directly to external speakers. If there is no audio out on your tv, this will not be an option.

Hi, I would like to help out.

Turn your TV back and on the left hand side look beneath the monitor. You will find the audio jack located beneath.

You can purchase wireless headphones at most electronic retailers. They will connect to the stereo RCA outputs on the back of the TV. Then you just turn the volume down on the TV. I hope this was helpful, best wishes.

You may have to connect the headset through a VCR or DVD player that does have the output connections.

i suppose you want to connect a 6.3mm jack (very big stereo headphones) to the 3.5mm connector on the tv ... google for >> 1/4" Stereo Jack to 1/8" Stereo Mini Jack Adapter

There is no headphone jack onthis model that I have found.
