doesnt charge, the part where the charger connects inside has broken

hello, i have had my blackberry for ages now, one day it was working fine and then i plugged it in to charge and it didnt respond. so i thought it was the charger so used my usb and it still didnt charge. the charger was really loose inside the phone so i took it out and the part where the charger goes inside the phone came out with the end of the charger. so i took it apart and then saw that the part where the charger bit inside the phone has snapped off the circuit board. i dont know how to fix it without buying a new phone or a new circuit board. help please.
