How can I replace my earphone socket

@courier the headphone jack is soldered to the motherboard. You would have to remove that first LG Rebel Motherboard Replacement easy enough. Now comes the hard part. To find a replacement. Problem with your Rebel is that there are not a lot of spare parts available . You could try and match one by measuring yours and checking at places like Digikey.com or Mouser.com for a replacement. Or get an inexpensive replacement motherboard from places like ebay.com and harvest teh port will require soldering, so make sure you have the tools and the know-how to replace it.
