Nintendo Wii U No Sound or Video

If there is no sound or video coming out of the television or stereo, then your cables may be disconnected. It never hurts to double check all of the connections between the Wii U and any other components. Make sure all the cables are securely plugged into the back of the console and into the inputs of the TV or stereo.

Also, make sure the TV and stereo are set to the correct input. You can also use known working devices and plug them into the same inputs as the Wii U to make sure that the TV or stereo are working properly.

Broken AV cables may prevent video or sound from coming out of the television or stereo. AV cables sometimes break and tear from being bent too many times. Try checking that the cables are still working with another Wii U, or by using a continuity tester to test that a signal can transfer from one end of the cable to the other. If the cables don’t work, they need to be replaced.

The connectors on the back of the Wii U can be damaged, meaning the console may not be able to output sound or video. Look for any signs of damage on the back of the console.

Also, hook up your Wii U to a known working TV and AV cable and make sure both audio and video are working correctly. If the console still isn’t working properly, then the motherboard may need to be replaced.
