While playing my Nintendo Wii a few weeks ago, I started seeing different colored pixels appearing randomly on the screen.

Wii Graphical Issues

From what I gather, the problem is caused by the Wii getting too hot in standby mode. Apparently the fan does not turn on in standby mode even when the Wifi is connected.

Luckily, it was still under warranty. After backing up my saves and content, I sent it to Nintendo for repair. About a week later I got a replacement Wii that works perfectly. To my surprise, my Virtual Console games, web browser, and saves were still there and working.

Hopefully this will not happen to the majority of Wii’s, we don’t need another Xbox 360 crisis on our hands.
