Be careful!!! Don't use knifes and friends to remove and clean parts
on the board.

Try to find someone with a proper desoldering station (Rework Station)
and let them do it. Its all too easy for the untrained to do more damage
than good to the board.

You can do most of the work by disassembling the system, packaging the
board into an antistatic bag and take it to the service center.
