Take the back off. find the board that ac cord is connected to.there are six screws,four plugs and a ground wire. carefully remove the plugs without breaking any of the wires.(the first time a plug is removed it can be quite hard to get out.) then remove the six screws and the ground wire connected to the chassis.lift out the board replace it with the new one and reverse the the instructions.
