My girlfriend bought me a Wii she found at a thrift store for 10 dollars, it didn't come with any cords or anything, but for 10 bucks I was willing to take a risk. I just bought the AV and Power cords from ebay, and tried to turn on the Wii and only got a black screen. I was wondering if this was fixable, or am I just screwed, or is it doing it because I don't have the sensor bar connected.
