Tools Needed
- Phillips screwdriver (longer one recommended for recessed screws)
- Plastic spudger or guitar pick (optional)
- Container to organize screws
Step-by-Step Disassembly
- Remove the Modem Slide or pull off the modem from the side of the console. There is one screw hidden underneath it — remove this first.
- Remove the Bottom Screws Flip the console over. There are 4 recessed Phillips screws on the bottom. Use a longer screwdriver as they can be quite deep.
- Separate the Shell Carefully lift the top shell off. Go slowly.
- Disconnect the Ribbon Cable Locate the wide ribbon cable connecting the top and bottom halves. Gently disconnect it by pulling it straight out (some units have a locking tab — lift it first if present).
- Remove Internal Components (as needed)
- Remove the screws holding the main board and drive assembly.
- You can now access the GD-ROM drive, main board, and power board for cleaning or repairs.
Reassembly Tips
Test the console before fully tightening everything.
Reconnect the ribbon cable before fully closing the shell.
Make sure all screws are accounted for.
Remember to reinstall the hidden screw under the modem area before sliding the modem back on.
