If you use a plug in set of headphones often, you have probably caused the contacts to spread apart inside permanently. The only solution (if that is the case) is to replace the headphone jack, or to (for the brave) attempt to insert a pin inside the jack and open the contacts so they are not pressed against the outside of the jack assembly.

When the speaker does not work, there can be different causes. Something got in the headphone plug, preventing the connection to the speaker when the headphone plug is out. Another bad connection in the phone, or even a defect loudspeaker. When you are no tech, just bring the phone to a repair shop and let a tech review the problem.
I would blow in the headphone connector with a bellow a photographer uses to blow away dust from the lens and sensor. DONT blow in yourself, because of the moist you bring in. And I would plug and unplug a few times to see if that can solve the problem. Not to often and if it does not help? please do option 1 visit a tech.
There should be a way to do that. 1st make sure speaker jack is fully inserted. If you still have same problem try normal headphones and see if there still is foreign hum- then if headphones work, check the size of both the jacks to see if there the same- you might just have wrong size jack. If that is not the problem the Impedance(ohm symbol) is probably wrong and the phone doesn't have enough power to drive your speaker.. Use a speaker with same Impedance, you might have to use a speaker with its own power supply to get appropiate volume. You could try your PC external speaker. I hope this has been helpful.
Switch off your phone and remove battery for 5 seconds and then put it back in. If it doesn't work, your phone's speaker is dead and you need to carry your phone to local LG customer service.
there is a black cord that comes with the speaker system with dual end headphone 3.5mm jack both ends that go from one speaker to the other main speaker is your right speaker left is the one with only jack insert the right has da power with sound cord toghether in one going out to amp with headphone insert also that goes to left peaker
Sound is not working. Headphones would work just fine but the built-in speakers stopped working. try to update and reinstall the drivers. The speakers would sometimes work for a second when removed the headphone jack. sometimes it was a short in the jack connection or just a bad connector in the jack. Sooo, just plugg in the headphone jack a bunch of times and after about 20 seconds the speakers will work just fine.
Make sure that the correct playback device is set as default in sound properties.
If all is well there then you could try a pair of headphones to see if the sound is working.
If headphones work ok then it is down to your built in speakers, not much you can do unfortunatly unless you are still under warentee
i did the exact same thing with the exact same problem. turns out that i left the speaker in the old cover! so double check that you took the speaker out of the old cover first and secondly that you reinserted it properly (right way up) in the new cover.
