Oh you bring me back here. desolder/solder carefully - i've done
  it only a few times. Easy to burn out motherboard. I never had a
  steady hand with a soldering gun. Should be numbered +
  replaceable. You can check out the FCC # if there is one on it,
  and find the diagram for the motherboard on the FCC website, if
  it ever was sent through the USA. I don't know if all boards
  have to get it or not.
