I flipped on my Wii and the video and audio were not functioning as it should. The video was distorted and black. The audio sounded like grinding gears.

I instantly thought the Wii's hardware was fried as the power went off and on several times yesterday during a ferocious thunderstorm since I leave the Wii plugged into the electrical socket.

After a lengthy investigation, I discovered that the video/audio cables connecting the Wii to the television were loose. Once, I re-established the links, the video and audio were restored!

The lesson I learned is that I should NEVER leave the Wii or any other gaming console plugged in when I am not using it.

Gamers beware!
