Introduction

5 Ohm 1/2 watt fuse resistor OR two 10 Ohm 1/4 watt metalized resistors
Controller board

What you need

Step 1

              Expansion Bay

Verify that the console is disconnected from the AC outlet before you begin.
Flip the console over on its back.
Take note of your model number, in case replacement parts are needed.

Step 2

Remove the expansion bay by applying pressure to the small clip on the expansion bay while prying it away from the console.

Step 3

              Top Cover

Locate and remove all four black 12mm Phillips #02 screws from the underside of the console.
Note: Remove the expansion bay to locate the fourth screw

Step 4

Internal components can be loose. Be careful that they do not fall out when removing the cover.
Turn the console right side up.
Remove the top cover by gently lifting the upper portion of the console.

Step 5

              Controller Port

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.

Step 9

              Controller Port

Flip the controller board on its underside so that the solder joints are exposed.

Step 10

Remove the F1 fuse by using the soldering iron and desoldering wick.
The F1 fuse is clearly indicated on the topside of the controller board.
If the F1 through-hole of the circuit board is not visible, you may clean the it by removing the excess solder by using the soldering iron and desoldering wick.

Step 11

If you are not using a fuse resistor, skip this step. Otherwise, continue.
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

Step 12

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.
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.

Step 13

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.

djresree - Dec 3, 2017

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?

djresree - Dec 3, 2017

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

rhedayi - Mar 18, 2018

I can help with this, email me at yahoo address

etra782a - Aug 15, 2019

bonjour Darren. Ma question est surement bête mais est- ce que cette manipulation est nécessaire quand seul le premier port de la Dreamcast ne fonctionne pas ??

Andrew Trumbo - Dec 12, 2020

I need this board, were do I find one?
