Flip the console over on its back.
-
Take note of your model number, in case replacement parts are needed.
-
-
-
Remove the expansion bay by applying pressure to the small clip on the expansion bay while prying it away from the console.
-
-
-
Locate and remove all four black 12mm Phillips #02 screws from the underside of the console.
-
-
-
Turn the console right side up.
-
Remove the top cover by gently lifting the upper portion of the console.
-
-
-
Disconnect the white controller cable by gently pulling the the cable while wiggling it back and forth until it detaches from the controller board.
Note that on some Dreamcasts the power board (on the left) overhangs slightly over the controller board, meaning one must also remove the power board at this stage. This is relatively straightforward, fortunately. Remove a screw each at the top left of the power board and at the bottom left of the power board, remove the white clip at the top left, pop out the white clip on the left of the power board and lift the power board out from the front where you have the white block containing eight pins that connect the power board to the sub board. Then proceed per the rest of this guide. Hope this helps.

Disconnect the white fan header from the controller port.
Perhaps list the battery type an battery holders that allow for easy replacement in the future?

-
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.

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

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
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 ??
I need this board, were do I find one?
easy job if you know how to solder
