[[File:IMG_1471.jpg|thumb|175px|Genesis II ready for disassembly]][[File:IMG_1488Genesis2Teardown-2.jpg|thumb|175px|A properly prepared work area]]Begin by preparing a flat, clean surface to work on, and disconnect any controllers, games, cables and add-ons that are connected to your console. The only supplies you will need besides the console itself are a standard Phillips-head screwdriver and (optionally) something to contain your screws. If your Genesis was recently plugged in to power, it's a good Idea to turn the power on wile the system is unplugged, and let it sit for a few minutes to drain the capacitors before starting. This will greatly reduce the risk of an electrical discharge that could lead to shock or damage to the console.

Turn the console over to expose the underside. Remove [[File:IMG_1472Genesis2Teardown-3.jpg|thumb|300px]]the plastic cover concealing the expansion slot as shown on the left, and set it aside. You can also remove the red "DO NOT REMOVE" sleeve on the connector itself if you like, although doing so will leave the connector pins more susceptible to damage during the remainder of the disassembly.

Set the base of the console aside and turn over the top plastic cover. Undo the three bronze-colored screws highlighted in the picture below, and lift off the spring-loaded door assembly that protects the cartridge slot[[File:IMG_1487Genesis2Teardown-4.jpg|thumb|300px]].[[File:IMG_1485Genesis2Teardown-5.jpg|thumb|left|300px]]

Returning to the base of the console, you will now need to[[File:IMG_1477Genesis2Teardown-6.jpg|thumb|300px]][[File:IMG_1476.jpg|thumb|300px]]remove the upper heat shield to gain full access to the system mainboard. Remove all nine screws highlighted in the images on the left, and lift the heat shield straight up from the base. Be sure that ALL the screws are removed before attempting to lift off the heat shield as it's made of cheap stamped sheet metal that has a tendency to bend.

Once the upper heat shield has been removed the top of [[File:IMG_1479Genesis2Teardown-7.jpg|thumb|300px]]the system mainboard will be exposed, this is where all the consoles working components are. The vast majority of Genesis II repairs and mods will involve soldering something to the mainboard. To remove the mainboard form the console base undo the two large screws on either side of the cartridge connector, and carefully lift it straight off. If you left the "DO NOT REMOVE" sleeve on form earlier you can use it as a grip to hold the board easier without risking damage.
