Hi! the problem started off with the sound disappearing in the left channel. after a little adjustments (which was unfortunate) there was total blackout (audio blackout). now after having opened up (and operated) the different colored wires, the problem seems to be disconnection (of solders) in the jack itself. having tried different combinations, i still havent figured out the right combination (blue and green in one wire-left channel : red and copper-right channel). i own a philips SHP2000 headphones.

Plug the power transformer into the bottom jack on the back of the right-channel speaker. This is the speaker with the on/off knob on the front.
Plug the audio cable attached to the left-channel speaker into the audio jack on the back of the right-channel speaker. The jack is immediately above the jack for the power cord.
Plug the audio jack attached to the back of the right-channel speaker into the headphone jack on a laptop computer (usually located along the left edge), or to the audio output jack on the back of a desktop PC.
Plug the speaker transformer into a surge protector and the surge protector into a wall outlet.
Turn the on-off and volume control knob clockwise on the front of the right-channel Inspiron speaker to activate the stereo speakers and adjust the volume.
check speaker wires connected to amplifier try to swap it between right and left speaker do the same to audio input jack (usually RCA jack). If it still works one channel only, probably the problem is in the power amplifier
If you use the headphone jack a lot and your missing the audio from the speaker and one channel from the headphone jack, then it's possible that some of the headphone jack connections have broken off of the PC board. The audio goes to the speaker through the headphone jack.
Please see this link for more info and read the section about the headphone jack.
Hi there. Check for shorted speaker wires on left channel. If not, disconnect speaker wires and check to see if headphone jack works. If left works, you may have a blown speaker. If left still doesn't work, left power amp blown. Thanks Paul
There could already be a problem with the speaker jack, if only one channel is consistently giving no sound on your system.
Try turning the male (connected to speaker wire) jack and you might hear a static crackle while doing this. If you get both channels to produce sound this way, you already have a failing audio jack, and may need replacement later on.
1. If you look at the headphone jack connecton do you see one or two black O-rings or black lines on the jack. If you only see one they are Mono headphones and you would only get sound out of the left side. If there are two black lines they are stereo headphones and you should get sound on both the left & right sides.
2. If after checking the headphone jack connection and there are two black lines on it then I would suggest try a different pair of headphones to see if a different set of headphones works fine.
If a different pair of headphones works properly the original headphones may be bad. If neither set of headphones work properly it may be the reciever that may need to be repaired.
I hope it's not the receiver, but let me know if you have questions.

First try the headphones in a different machine, such as an mp3 player or cd player to make sure the headphones still work.
Try going to the start button, then settings and control panel. Then select "Sounds and Audio devices" Down at the bottom you should see "Speaker settings." Click the "Advanced" button and then select stereo headphones.
Then, place the headphones into the green audio jack (or the headphone jack up front if you have them), play some music, and then gently wiggle the jack to see if some of the sound makes it into the headphones. If not, try slowly pulling the headphones out of the jack while the music is plaaying. you might find that the jack has slipped a little and may play only if your connector is slightly pulled out or more firmly pushed in. If his helps, then your audio connector is loose and you should replce the sound card. If the card is on the motherboard, you can disabled it when you put a new card in.
Sounds like the audio return wires aren't connected. On the motherboard, there is a sound jack on the back left side of the mobo. The jacks from the front audio panel connects to it. Both the Left and Right channel have an out and an in connector. These send the signal to the headphone jack on the front panel and return the signal to the rear output jack if a headphone is not connected. Look for looe or broken wires. The other spot to check is the front headphone jack. If a headphone plug was pulled out or pulled sideways, it could break the solder joint on the PCB panel or break the shunt feeding the singal to the rear jacks. Hope this helps.
