SNES DC Jack Repair

by

in

I recently acquired an old Super Nintendo Entertainment System (SNES) to enjoy some retro gaming. However, upon setting it up, I found that the power connector was damaged. This defect hindered the power cable from providing consistent energy, occasionally resulting in the console failing to power on.

Opting not to return it for fear of getting an even more discolored replacement, I decided to take matters into my own hands and repair it myself!

And now, without further delay…

Tools

  • The SNES screwdriver/bit is a specialized tool with a unique tip designed to remove SNES security screws, often referred to as Security Screwdrivers, which I purchased from eBay.
  • Soldering iron, solder.
  • Phillips screwdriver.
  • De-soldering tool.

Parts

  • SNES back panel replacement. (I got mine from eBay)

Steps

Flip the SNES over and unscrew the marked circles.

You will then see the following:

To remove the power switch, unscrew the two screws holding it in place.

Carefully remove the spring, ensuring you note its original position, as you will need to replace it exactly as it was. This step is necessary to disassemble the cartridge eject mechanism of the SNES.

After its removal, this will be the view:

Carefully detach the ribbon cable that connects the SNES ports to the main board, ensuring to follow the direction indicated by the green arrows.

If your cartridge connector is removable, gently pull it out from the board. Should you have a replacement, this is the point where you can swap in the new one and then reassemble the SNES.

Additionally, you may now proceed to remove the motherboard from the plastic housing.

After completing that step, flip the board over to its backside and carefully remove the screws marked in green, making sure to remember their original positions. Then, use a soldering iron and a desoldering tool to detach the solder points marked in red.

Rotate the board and remove all screws securing the large aluminum heat sink, including the one fastening the voltage regulator. Remember to remove this particular screw to prevent any damage to the regulator.

Removing the last two screws will free the plastic assembly (photo not taken). After their removal, rotate the board so the ports face you and begin to detach the plastic from the motherboard. This may require some effort, as the metallic pins of the jack tend to get stuck, and note that these pins are part of the plastic piece. A flat screwdriver can be used to gently pry the plastic up, allowing the leads to clear the motherboard’s holes.

A rocking motion is advised to safely dislodge the plastic from its position.

For a faster approach, you could use a rotary tool to cut away the plastic, especially since it will be replaced later.

After completing this step, you should have the following view:

Install the new plastic assembly and solder it securely into position.

Begin reassembling everything in reverse order. You have finished.
