Step Two:
Once the screws are removed separate the top and bottom halves of the casing. Next turn over the
system and locate the seven-to-eight screws that hold down the top RF shield, please see picture three
below. Unscrew these screws. Next unscrew the two screws holding down the mother board, please see
picture three below.

Step Three:
Now that the top RF shield and the mother board have been unscrewed go ahead and remove the top
RF shield. Next unscrew the six screws holding down the spring loading mechanism, please see picture
four below. It is important to note two of the screws holding down the spring loading mechanism are
longer than the rest of the screws used in the system, as such it is important to remember where these
screws go when you reassemble the unit, please see picture four below.

Step Four:
Now that the spring loading mechanism has been unscrewed please remove it from the system. It is
recommended that you lift the entire mother board out of the system to facilitate this procedure. Once
the spring loading mechanism has been removed please remove the 72-bit pin connector as well. Finally
flip your mother board upside down and locate the three cables located in picture five below.
Controller Port One
Disconnect these
three cables from
themother board

Controller Port Two
Picture Five: Mother board upside down
In order to disconnect the three cables from the mother board we recommend the following procedure.
Using a flat head screw driver press on the sides of the cable as it inserts into the port. This should begin
to dislodge the cable from the port. Do not yank on the cable itself as this will most likely result in
damage to the cable. Once you have disconnected the appropriate cables please proceed to step six.

Step Six:
Now that the controller port has been disconnected from the mother board it is time to remove the
controller port from the system entirely. Please flip over your system and locate the two screws holding
the controller port face plate in place as seen in picture six below.
Philips head screws
Picture Six- Controller faceplate screws
Unscrew these two screws and the faceplate should life off. Once it is removed simple extract the
defective controller port. After it has been removed insert the replacement one and then reattach the
faceplate. Warning: The faceplate will crack if the screws are overly tightened. Tighten them to the point
where you first meet resistance and no further or they will crack. It is very easy to do. Once you are
done please procedure to step six.

Step Six:
Now that you have installed the replacement controller port it is time to reassembly your system. There
are a few hints on how to do this to prevent headaches down the road.
Picture seven below demonstrates how the three cables should look when they are hooked up correctly.
Picture Seven: Proper arrangement of the three cables
Once you have the controller port cables attached go ahead and insert in the mother board into the
system. It is important to make sure during this period that you do not pinch any of the cables between
the mother board and the spikes on the case you screw the mother board to. It is easy to do and will
result in damage to that cable when you start to screw everything together.
Next reinstall the 72-bit pin connector and then advance to step seven.

Step Seven:
Next you need to install the spring loading mechanism. When installing the spring loading mechanism it
is of critical importance that you place the lip of the spring loading mechanism underneath the mother
board. If you examine the bottom of the spring loading mechanism you will notice a slight lip on the
bottom, this lip must go underneath the mother board as seen in picture six.
The mother board in this picture has been removed from its housing and flipped upside down in
order to show the correct placement of the lip of the spring loading mechanism. Notice how the
lip slips underneath the bottom of the mother board.

Picture Eight: Proper placement of the lip of the spring loading mechanism
Once the lip is correctly underneath the mother board you can reassemble the unit taking care to note
the correct placement of the longer screws on the system, see picture three. If after you install the
replacement Nintendo NES controller port it fails to function properly please see the troubleshooting
section at the end of the guide or contact us at [email protected]

Troubleshooting Section
While we hate to hear that something didn’t go as planned, although sometimes problems are
encountered. This section of the guide is designed to help you troubleshoot what is happening. Please
read the list of available problems and choose the one that best matches yours. If you need additional
assistance please contact us at [email protected].
1) My spring loading mechanism does not work
a. This is a direct result of the lip of the spring loading mechanism not being correctly
placed underneath the mother board during reassemble. Reassembling the unit with the
lip underneath the mother board should solve the problem.
2) My controller port(s) doesn’t work
a. Are the ports plugged in? Did you make sure that each port was connected to the right
port on the mother board? Did a cable get squashed between the mother board and
peg on the casing when you were reassembling the system?
3) My system doesn’t power on
a. Did you plug the power cable back into the mother board?
