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.

Next you will need to remove the four highlighted screws on [[File:IMG_1474.jpg|thumb|300px]]each corner of the console base. They are a bit tight at first, but should come loose with minimal effort. It may be necessary to turn the console back over and gently tap the it to get the screws to come all the way out of their holes. Once the screws are out, the top cover should lift straight up from the base.

==The Upper Heat Shield==

Returning to the base of the console, you will now need to[[File:IMG_1477.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.
