The same problem here. I solved it like this:
You must open the device. There will be a PCB with outputs and inputs. You must must detach it by removing screws on outside and then disassemble the PCB from two plastic pins to get the PCB rotated (I used plice to detache it one by one) and the conections of jack socket visible. In my case one od the lanes to the hot pin was broken. I checked that with Ohm meter 'cause it wasn't clearly visible with an eye. So having the PCB more or less secured I started to clean the lane a little bit to have a chance to put the solder layer near the pin and breakage. Get some really precise soldering device. It's a precise job. Do not overheat the diode which the lanes goes to. After placing some of the solder I checked the new connection by placing a jack into the socket and Ohm meter once again. All was perfect and working after assembling. Piece of cake.

My dell latitude d510 internal spk is ready but output headfone jek not working


these are fairly passive in that if a headphone or earpiece is plugged in, they switch the output from the internal speaker to the external speaker. So, it's usually one of a few problems.
  • The jack is mucked up, and needs replaced.
  • The headphone plug wires have a broken connection
  • The headphone needs power to amplify, and that's not working.
If trying another headphone or earpiece you know is working doesn't work, it's the jack itself. They can only handle so many uses before they either fail closed, or open or completely. Depending on which one, either:
  • neither speakers nor headphones work.
  • only speakers work
  • only headphones work
Replacement necessitates opening the case and replacing the jack. For that, there's no help.

Sylvania wireless headphones



Instructions
1
Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
2
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.

3
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
4
Plug in the transmitter and turn it on. Charge the headphones if necessary.
5
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.

Can i hook up my PC to my sterio system through the headphone jack on the stereo to the PC HEadphone jack? been trying to get it to work on Auxilary but no sound :( please help


If you are still working on the question you asked about. This is what I would do. One of two things:

First: purchase an adapter that goes from your laptop 3.5 mm headphone jack to the microphone input if there is one.

Second: Would be to purchase what is called a "Cassette Tape Adapter". This will take your 3.5 mm headphone jack and play it through your cassette tape area of your stereo.

I hope one of these is a solution that will help you. -- wicc --

Can I watch a DVD and use the WH-930 headphones to hear it better?


Most DVD's have line-level outputs which will NOT drive headphones. You need to run the audio line outputs, which are usually RCA jacks to jacks on an amplifier and then plug the headphomes into that. An inexpensive source for an amplifier is OFTEN at thrift shops. Run the pair of cables into jacks that would likely be labeled TAPE INPUT for example. FInd one that does have a headphone output jack on the front.

Ive connected my laptop to my tv via hdmi cable,get great picture but no sound through my tv only off the laptop,ive gone to control panel,sounds,playback but the is only 2 options neither of which says...


In all the laptops the HDMI sends only the video. If you want to send the sound you will have to use the analogue audio outputs - line out of your laptop has it (some allow the headphone jack to be configured as one) or just the headphone jack. You will need a cable like

I have a LG 19LE3300 television and i whant to be able to connect an Infra red headphone while being able to listen by the speakers at the same time. actually when i connect the hearphone it disconnect...


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.
Take care and please

My sony dav-s-400 system keeps activating headphone port output.


Just had and fixed the same problem that hundreds of people are suffering with this system!!
Sony DAV s400 - same problem, won't play though speakers and display indicates that headphones are plugged in - when they are not. Fairly easy to fix and took me less than an hour from start to finish:
1) Remove top cover
2) Remove circuit board that has Audio In/Out phono scockets (to get access to Amplifier Circuit Board)
3) Remove Amplifier circuit board (has the speakers attached)
4) Turn it over and remove copper heat shield
5) Resolder joints where the big brown capacitor is and where the wires go to the front headphone socket...and any other dodgy joints that you find
6) Reassemble.

Sennheiser rs-126 connection


Yes, you may. RCA connections are universal, just don't connect an input lead to an output jack: you might damage the jack.
