Companion3 plugged into a tv through headphone connector, no sound coming out

It should be in the TV audio settings. What is the make/model of the tv?

Hook up a computer to it. The tv could have an hdmi connector or monitor connector (check the back of the television to see which type of connectors you have available) so just plug a cable in from your pc to the tv.

For sound, a simple computer cable plugs into the headphone jack of the computer to the back of the television. If you have a PC, you may have a series of connectors for stereo surround sound systems (like a sound card). I use a simple jack that plugs into the headphone jack (stereo speaker jack) and also plugs into the pc audio in port on the tv. Now I just select the input (pc) from the sony menu and select the option for sound input and voila. As long as the pc is connected to the internet, your tv is your new monitor.

Just get a headphone jack that does not shut off the speakers and have your dad plug his headphones into that.

The socket for the jack on the set has a leaf connection that when you insert the jack moves aside routing sound to head phones and cutting it off to speakers= the socket for the jack is out of position inside, either needs to be replaced or tweaked inside just a little.

Not much else can cause this if the headphones work.

Hi,
First you need to make a test to adjust your headphones wireless system..
.pls follow the step below:

• "Connect the headphone base" TO " headphones output of TV" with 3.5mm stereo headphone jack cable (than Tv should mute ) Infra red headphone pilot lamp should flicker in parallel to voice coming from TV

• Infra red headphone should have a rotary adjustment on it.. "Volume" adjustment
  
• while TV talking , when you sit in front of the Infra red headphone (it works point-to-point ) you will hear the voice of TV, than adjust volume properly...Thats it..now lets go to second step..
  
• Your headphone's Base should either "3.5mm stereo headphone jack" or "RCA Stereo jacks" or "bot"h..After completion of this test ,I recommend you to switch / use "RCA Audio output plugs-white/Red cable " on the back of TV instead of TV's headphone output ,since it mutes the whole sound..RCA output plugs of TV work independently from the TV's master volume control..of course you need RCA cable to connect this..
  

Hope this helps!..if more help requires pls let me know.

What are you plugging your 2 RCA connectors (from the headphones) into on the television?
You are correct, usually:
White = Left Red = Right

In this case
Black = Left Red = Right
Not sure....guess some manufacturers need to be different...
Back to the issue,
You to need to connect the Black to White and Red to Red to the TV BUT you need to make sure you are connecting to an OUTPUT and not to an INPUT on the TV. Most newer TV's do have an "audio out RCA jacks" on the TV but not all. It should be labeled at the connector if it is an output, or just another input. You can always consult the TV manual to be sure.

Few things you can do to test

• Does your TV have a "headphone jack", use the adapter (2 RCA female - 3.5mm connector) to plug into the headphone jack and see if there is sound
• Connect the Black and Red RCAs from the headphones directly to the another output, like a DVD player, CD Player etc....

I hope this helps,

I had the same problem with Brookstone wireless headset the only solution I found was plug in the red and white connectors to your cable box it works perfectly that way. Just make sure the red cable connector from the transmitter is connected to right red input connector on the box. I have a Comcast cable box. Now I need a solution for them on my PS3?

It does not look like you have the switchable headphone connector that you can use a pair of headphones and will cut the audio to the tv speaker out.If you are using the audio out connectors in the rear of the tv all you can do is lower the tv volume when you are using the headphones(fixed audio)
