    • With the bottom side of the GameCube facing upward and the screws removed, carefully pull the outer shell of the unit away from the top half.

    • Move the GameCube so that the inside is facing upwards.

    This can also be done whilst being in the normal upright position after all 4 of the 4.5mm Gamebit screws have been removed. Pull the top of the shell directly upwards and it should slide off easily.

    Less chance of snagging any wires or parts.

    • Gently press down on the clips located on either side of the back panel.

    • Carefully remove the back panel from the GameCube.

    A second picture clearly showing which direction to pull the back panel away from the unit would be nice.

    • Unclip the controller ports at the front of the unit.

    • A ribbon cable (outlined in orange) is still attached to the unit. Do not disconnect this cable.

    • Controller ports are where the controllers plug into the game console, and are a half circular shape.

    well... what happens if accidentally i disconnected it?

    negroporexcelencia - Ответить

    presumably nothing major. The CMOS battery is attached to the controller ports, so the most i'd expect is that the gamecube loses it's date/time setting. As long as you reset that before jumping into animal crossing or something, you should be fine. I'm currently doing a teardown of my gamecube, and if something does prove to have gone wrong, i'll report back.

    okay, i finished putting it back together. gamecube works fine and surprisingly still remembers what year it is. boots into smash bros and shows memory card contents fine.

    • Use a Phillips #2 screwdriver to remove the two screws on the back of the control port.

    • Carefully separate the gray outer casing of the control port and the circuit board.

    That step is not needed for the laser replacement.

    • The left side of the unit contains the cooling fan and its housing.

    • Carefully remove the two screws attaching the cooling fan housing to the unit.

    • Do not detach the red and black cooling fan wire from the main unit. Boxed in orange.

    Why can't the fan wire be detached?

    Josh Hobbs - Ответить

    It can, but you might not want to

    • The optical drive is secured to a metal plate.

    • Using a Phillips #2 screwdriver, unscrew the twelve screws that are around the outer edge of the optical drive.

    Are these 12 screws the exact same kind like the 2 that were on the fan?

    blaise ventura - Ответить

    Yes! As far as I can tell anyway. Makes sense, too since opposite the fan you have five of the same holes as well.

    • Carefully separate the optical drive assembly from the rest of the GameCube unit.

    • The optical drive assembly is secured to the motherboard underneath by a slot; some force may be required to carefully free the assembly.

    • The metal plate and the actual optical drive will remain attached.

    • At this point, your optical drive assembly should be separated from your GameCube.

    • Flip the optical drive assembly upside down.

    • Remove the six screws with a Phillips #1 screwdriver.

    • Gently lift and remove the metal plate.

    • Be careful not to disturb the brown ribbon cable.

    If you are just doing the lens power adjustment, from this step skip straight to step 17. Steps 11-16 are unnecessary unless you are replacing the lens completely.

    • Remove the blue wire by gently pulling.

    • Don't pull on either the wire itself or the connector attached to the board.

    • Disconnect the brown cable. This is done by gently pulling the black tab away from the white plastic. This will loosen the tension on the brown cable, allowing it to slide away from the tab gently.

    • Remove the four Phillips #1 screws connecting the circuit board to the optical drive assembly.

    • The fourth screw is located behind the screwdriver in the third picture.

    A helpful addition/change to this step would be to include a photo of where/how to remove the brown ribbon cable (maybe also include this terminology in the text, instead of just “cable”). Furthermore, the yellow box to indicate the blue cable highlights everything except the part that you need to remove, which is a little confusing.

    Thanks!

    I cannot get the 4 little screws to go back into the board once removed. There is nothing for them to bite into - how do I get this board put back together?

    • Release the small clip holding the board down.

    • Gently remove the circuit board (the large green square) as shown in the three pictures.

    • DO NOT SEPARATE the red wire or the white ribbon cable connecting the circuit board to the metal plate.

    • Red Wire

    • White ribbon Cable

    What would happen if I accidentally separated the white ribbon cable... because I watched a video of some guy going through this same process. Separated all the cables and his worked. My cube stopped reading disks recently. Laser is calibrated properly. Begins to spin then stops

    Ps

    Is there anyway I can save my cube

    kyleharms10 - Ответить

    I'm just guessing here, but I think they mean there's no need to separate those cables to complete the repair—just be careful not to pull or stress them. Like you said, nothing bad will happen if you choose to disconnect a couple cables. As for what's wrong with your cube, you might want to try asking your question over in the Answers forum.

    Jeff Suovanen -

    There is a small tab to the left of the red wire that you need to pull out to release the circuit board.

    patriotsfansince87 - Ответить

    Why do we need further disassembly that this ? The potentiometer is already accessible at this point. Why do we need to tear down the lens from it’s slot in step 16 ?

    Startide Harlock - Ответить

    Good question! I’m wondering the same thing.

    Ben Zelinsky -

    You don’t. You can stop here if you’re doing the laser potentiometer calibration.

    The plastic post closest to the white ribbon cable can be annoying to deal with to remove the circuit board. Removing the white ribbon cable carefully with blunt tweezers can be necessary to remove the circuit board.

    • Use a flathead screwdriver to carefully release the four plastic clips holding the drive assembly together.

    • Carefully use a screwdriver as leverage to unscrew and release the last clip.

    Since this step uses a flathead screwdriver, it might be useful to include that in the list of required tools at the top.

    • Gently lift the metal plate off the drive assembly.

    • Be careful not to sever the red wire or the white ribbon cable still attached to the two halves of the drive assembly.

    • Then, flip the two halves of the drive assembly upside down.

    • Use a flathead screwdriver to release the two clips located on the back half of the drive assembly.

    • The final clip doesn't need to be released; the top half of the drive assembly will slide away from the lower half.

    • Finish removing the top half of the drive assembly from the base.

    • Be careful not to detach the red wire or the white ribbon cable still attached.

  16. Optical Laser Lens Power Adjustment: шаг 16, изображение 1 из 2 Optical Laser Lens Power Adjustment: шаг 16, изображение 2 из 2
    • Once the top half of the drive assembly is detached, turn it upside down.

    • Using a Phillips #1 screwdriver, carefully remove the three final screws near the lens assembly bars.

    • Extract the final three screws and remove the lens assembly.

    what kind of screws are these on the laser lens i lost one and need to buy new ones cause i cant find the 3rd

    • Rotate the assembly so that the green circuit board is facing you as shown in the first picture.

    • Flip board over so it is oriented as shown in the second picture.

    • Using a Phillips #1 Screwdriver, turn the small knob very slightly counter-clockwise—a few degrees to, at most, one-quarter turn.

    • You can find instructions for testing to make sure your repair worked at this link.

    Isn't it supposed to be counter clockwise? I read somewhere that turning it clockwise weakens the laser.

    Daniel Cital - Ответить

    Agreed, it should be counter-clockwise.

I don't understand why you have steps 11-17. In step 10, you can clearly see the board with the screw that needs adjusting. Taking apart the rest of the GameCube is utterly unnecessary. After following the guide in full, I thought, 'Why did I just dismantle all that other stuff when I didn't even NEED to?'

Once the assembly is removed from the metal covering the board, it is a simple matter to turn the screw to increase the laser strength. I did this after my initial adjustment didn't work. I ignored steps 11-17 and everything works perfectly now. My old games which simply would not load, now do. Thanks for the advice leading up to step 10 though. That part was helpful.

Johnny H - Ответить

I wouldn't say it's a quarter of a turn, a few degrees clockwise do the trick. I tried a quarter of a turn the first time and it made the disk unit useless as it didn't recognise any gamecube disk.

Jaime Aluja - Ответить

Thanks for the detailed pictures! I was able to get everything taken apart, and fixed the read error I was having after a couple of readjustments.

One important note: the lens screw should be turned counter-clockwise, not clockwise. A quarter turn is also likely to be too much; better to adjust a few degrees at a time and test repeatedly until the right setting is found.

gameFAQs.com has a lens calibration guide, with notes on how to reassemble the GameCube for testing without screwing everything back together.

I also agree that steps 11-17 can be skipped, as well as step 5 to remove the controller ports.

Lauren - Ответить

Steps 11+ are definitely not needed and 1/4 turn is more than 200ohms, way too much. It has to be moved by a hair (almost literally), the potentiometer is extremely sensitive. And I would personally recommend some form of multimeter, as to not go turning that screw blindly.

Nicola Lahaie - Ответить

Great guide, this fixed my problem. Would like to be clarified if you need to follow steps 11-17 make the power adjustment.
