Recently moved. Hooked up the old 360 and the Wii. Both are via the old AV cables (the lame red, yellow, white ones). I turn on my crappy 40" Samsung 780p TV to use the game systems, and the screens colors are now black and white. There's also no sound. When watching a normal TV show, there's no issue. But any change of component, and black and white colors abound. To add the mystery, I bought an hdmi cable for tv to xbox. I figured "fuck av cables". It worked. 360 works perfect, yet the Wii with its av cable setup is still grey screened. Takes me to the main menu fine, but everthing is in black and white. Side note: the av wires are hooked up right. Dunno wtf is going on.
