Nintendo GameCube power loss after on for 20 mins

Troubleshooting - Power

 

No Power

Make sure that the words "Nintendo GameCube" are molded into the AC adapter. Unlicensed products are not fully compatible and may not work correctly.
Make sure the Nintendo GameCube has good ventilation. For best results, make sure that the system rests on an open, flat surface. Avoid operating the Nintendo GameCube while it's on carpeting or inside an enclosed space.
Check the vents on the sides of the Nintendo GameCube for a build-up of dust. The system will shut down if it cannot vent properly to prevent overheating. If there is a build-up, remove it using a vaccum cleaner with a soft brush attachment.
Avoid the use of unlicensed products such as memory cards, controllers, and cheat devices. Some of these products are poorly manufactured and may result in damage to your system. If one of these products is attached to your system, remove it and try resetting the AC adaptor (see below).
Make sure that your wall outlet works. To check it, try plugging a lamp into the same outlet where your system was plugged in. Turn the lamp on the verify the outlet works. Also, make sure you are not using an outlet that is operated from a wall switch. If you do, make sure the wall switch is in the ON position.
Make sure the AC adapter is attached properly. Firmly plug your AC adapter into the back of the Nintendo GameCube (the port is labeled DC 12V IN) and into a working wall outlet.
Press the power button on the Nintendo GameCube and check to see that the red power light on the top of the Nintendo GameCube illuminates.

If this fails, try resetting the AC adapter.

Unplug/remove all accessories from the system (including game discs, memory cards, and all controllers), hookup cables, and the AC adapter from the outlet and Nintendo GameCube.
Let the system rest for about 45 seconds. While you're waiting, check to see that the cords on the controllers, AC adaptor, and Stereo AV cables/Component Video cables (or RF Switch) are not frayed or have exposed wires (this can cause the system to shut off); if so, you should replace those parts.
After the 45 seconds, Plug the AC Adapter into the system and wall outlet. Press the power button to see if the system works.


If the system works, turn the power off and plug ONE accessory into your system, then turn the system on to see if it still works. Repeat this process with ONE accessory at a time. If your system doesn't work once you put a particular accessory in (GameDisc, controller, Memory Card), there may be something defective with that accessory.
If the power does not come on, a repair will be necessary. Because it is not possible to determine which item (Control Deck or A/C Adapter) needs repair, please call our Consumer Service Department at 1-800-255-3700 to discuss available options.

If the power is continually shutting off after aprox. 30 minutes, listen to hear if the fan is working while the system is powered on. If the fan is not running, the problem will continue (Nintendo GameCube is avoiding overheating) and the system will need repair.

Power Light Shuts Off
If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.

its firmware problem! Wii has new firmware updates, try update to it using wifi

If the power shuts off during game play or resets after 30 minutes after the system is turned on then turns off and won't turn back on or the fan isn't working, the system needs to be repaired then. This problem that you have might be the fan thats causing this problem then.

did you check the back of all your discs for scratches thats the problem or gamcubes broken down if you try a new game and it does the exact same thing send your gamecube to nintendo for repair hope this helps.

check all your cables, i had the same problem and it ended up being a joystick with an exposed wire. i actually returned the first gamecube because of this but when the second one had the same problem i ended up searching on the net for answers. the gamecube shuts itself down as a safety feature so just double check all you cables, the problem joystick in my case was hardly noticeable so look closely, gluk!!
