usb charging port problem

[ScoobyDoobyDoo]

HELP my LG Optimus Elite has had a problem for weeks. It would charge for a few seconds and then stop. At first i thought it was the battery,so i got a brand new one. But it would do the same thing. And now I think its the charging port. I believe it has a short in it. But the problem with that is i dont know how to take the port and connector out of the phone. I already got the motherboard out. I dont know how to get the part where the battery sits at out. could someone show me how to get it out? HELP PLEASE. ASAP PERHAPS? THANKS IN ADVANCE.

Have you thought that the charger needs to be replaced
