Remove the single screw from the mount and swing it out of the way then remove the CF card. Next loosen the 6 screws holding the case together. A #0 Phillips screwdriver works well for this.
Gently pry apart cases with small flat bladed screwdriver. Cases should come apart with just a slight amount of pressure. Be careful that the case seal does not get damaged. Remove the 2 screws holding the board to the back case. There are no wires attaching the board to the case.
Be careful not to bend the 6 little tabs on the board when handling it. They are the contacts that touch the main board when the case is assembled.
This is the broken solder connection that I found.
Figured I would try to fix it myself since I'm cheap and ride a KLR too.
