How to Unbrick a Wii With a Black Screen Without a Modchip

Check the audio/video connection for your Nintendo Wii system. By default, this connection is made with the composite cable that comes standard with your Nintendo Wii. This composite cable is made of two sets of prongs that are on separate ends of a black cable. Each set of prongs has one red, one yellow and one white prong. These prongs must be color-matched to the composite port sets on the back of the TV and the rear of the Wii, which also feature red, yellow and white colors. If the colors of the ports and prongs are mixed up, disconnect the cable and make the proper connections.

Check the component audio/video connection if you have opted for that configuration over the more standard composite video cable connection. A component cable features two sets of prongs similar to the composite cable, except these are blue, red and green in color. Ensure these prongs are correctly matched to the blue, red and green component ports on the back of the Wii and the back of the TV.

Power down your system by holding the power button for at least 10 seconds if the screen of your TV is blank and your Wii's power light is glowing either orange or green. Alternatively, disconnect the power adapter from the power outlet if holding down the power button does not work.

Turn the Wii back on and then select the "Menu" button at the bottom left of the Wii's main menu using the Wii remote control. This will bring up System Settings. Accessing this menu may be necessary in order to prevent the device from bricking itself again, even if the screen is no longer black.

Select the "Wrench" icon by pointing your Wii remote, which in turn accesses the System Settings screen.

Click on the blue arrow to the right of the menu screen using the Wii remote. Click twice to reach the third screen, then select the "Wii System Update" option.

Choose "Yes" to accept the terms presented and wait while the Wii automatically updates. This will fix your bricked Wii.
