Be gentle with the white controller cable as it can be a bit fragile. Disconnect the white controller cable by gently pulling the the cable while wiggling it back and forth until it detaches from the controller board.

If you are not using a fuse resistor, skip this step. Otherwise, continue. Insert and solder the new fuse resistor to F1 socket.

  • Insert and solder the new fuse resistor to F1 socket.

  • The fuse resistor should sit on the topside of the board and the leads should be exposed on the underside. Orientation of the fuse resistor does not matter

  • The 10M 1/2 watt resistor in the picture is used to depict what a fuse resistor might look like.

If you have already used a fuse resistor to complete the previous step, you may omit this step. Insert and solder the parallel 10 ohm 1/4 watt resistors to the F1 socket.

  • Insert and solder the parallel 10 ohm 1/4 watt resistors to the F1 socket.

  • The resistors should be laid out on the top side of the circuit board and the leads should poke out from the underside. The orientation of the resistor does not matter.

  • The 1/4 watt resistors shown in the picture are used to depict what parallel resistors should look like.

Verify that the resistor(s) leads do not touch other components on the topside of the circuit board. Otherwise, a short circuit may occur when you power on the system.

Hello, Darren. I am having the utmost difficulty doing this with two 1/4 watt resistors, as you have demonstrated. I have three dreamcast systems, I would like to repair (all with a bad controller port.) What would be the chance that I could send you the ports, packs of resistors and and solder and pay you to do this to all of them?

I would even be willing to give you two of them! I just want one working system!

I can help with this, email me at yahoo address
