Replacing the F1 fuse on the controller board of the Sega Dreamcast. Soldering is required for repair.

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

Edit 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.

Edit Step 2  ¶ 

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

Edit Step 3 Top Cover  ¶ 

  • Locate and remove all four black 12mm Phillips #02 screws from the underside of the console.

  • The fourth screw is hidden under the expansion bay if it has not already been removed.

Edit Step 4  ¶ 

  • Be careful that the internal components do not topple out.

  • Flip the console topside up.

  • Remove the top cover of the chassis by gently lifting the upper portion of the console.

Edit 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.

Edit Step 6  ¶ 

  • Remove the four 14mm Philips #02 located on the controller board.

Edit Step 7  ¶ 

  • Disconnect the white fan header from the controller port

Edit Step 8  ¶ 

  • Remove the controller board by lifting it up from the controller port.

Edit Step 9 Controller Port  ¶ 

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

Edit 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.

Edit 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

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

Edit 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.

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

Edit 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.

To reassemble your device, follow these instructions in reverse order.
