Ok, so I just got a used Wii and I hooked it up. The thing works great there is just one thing. On the main screen and in Wii Sports, there are random black lines that appear in the screen. They flicker and are at random places. It's quite annoying actually. I tried my Wii on a tube tv and on my LCD tv and still the same thing. It's hooked up with the original wires it came with (yellow, white and red wires). Has anyone ever seen this before?
