No video and audio in the System Menu.

When I boot my Nintendo Wii Normally, it will not show video or audio. When I boot to Priiloader (My Wii is homebrewed) when I select the option System Menu, The Console locks up. Trying with the Homebrew Channel, When I select "Exit back to System Menu", it locks up again. Can Anyone help me fix this issue? SOLVED: The culprit was the Nintendo Wii's Wi-fi Board not working correctly.
