Restoring Extremely Yellowed Sega Dreamcast - Retro Console Restoration
Sega Dreamcast Teardown - Detailed Disassembly Guide
Flip the console over on its back.
Take note of your model number, in case replacement parts are needed.
For the disassembly of the Sega Dreamcast I used a Phillips tip for my screwdriver.
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
Remove the expansion bay by applying pressure to the small clip on the expansion bay while prying it away from the console.
Turn the console right side up.
Remove the top cover by gently lifting the upper portion of the console.
Verify that the console is disconnected from the AC outlet before you begin. If you have just powered off the system, give the capacitors a few minutes to discharge before you begin working.
Remove the white female pin header by clamping the clip and pulling it up gently from the power board.
Remove the two 10mm Philips #02 screws that are fastened to the power block.
Do not bend the male pin header between the mounted head when you remove the power supply from the chassis.
Remove the power board by using both hands to gently lift the power board away from the console.
Remove the clear plastic film that is tucked between the power supply and the chassis.
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.
Remove the four 14mm Philips #02 screws located on the controller board.
Disconnect the white fan header from the controller port.
Remove the controller board by lifting it up from the controller port.
Detach the orange cable by giving it a gentle pull while wiggling the cable back and forth until it loosens from the logic board.
Detach the cables by gently pulling the three GD-ROM cables to remove them from the logic board.
Remove the two black 12mm Philips #02 screws located on the left side of the GD-ROM bracket.
Remove the GD-ROM by gently lifting it from its base.
Remove the white fan header by gently pulling it away from from the controller port.
The white fan header may already be detached if you have completed the Controller Port Disassembly Guide.
Remove the two 8.5mm Philips #00 screws from the fan bracket.
Remove the five 10mm Philips #02 screws from left side of the logic board cover.
Remove the three black 12mm Philips #02 screws from the right side of the logic board cover.
Lift the metal cover from the console.
Before handing the logic board, you may want to use a grounding strap to protect the device from static charge. If you do not have a grounding strip, you may ground yourself by touching a large metallic object.
Remove the logic board and set the logic board on an anti-static surface.
To reassemble your device, follow these instructions in reverse order.
How to Restore a Yellow Sega Dreamcast the Easy Way
This video will show you how to make your yellowed Sega Dreamcast look almost new again.
Coat the plastic in hydrogen peroxide to fix discoloration. Hydrogen peroxide works well on plastics that have turned entirely yellow instead of in just one spot. Fill a plastic bag with enough hydrogen peroxide to cover the plastic. Stick the plastic in the bag of hydrogen peroxide and lay it out in direct sunlight. Wait 3-4 hours before rinsing it off with clean water.[5]
You can purchase hydrogen peroxide at a drugstore or big box store.
If you’re treating some sort of plastic mechanism, make sure you remove all the parts that aren’t plastic before putting them into the hydrogen peroxide.
You can also use an old toothbrush to scrub the hydrogen peroxide onto the plastic if desired
