I was about to hit a few ball in the baseball training, then all of a sudden I got nothing but a mesh of colors on the screen. Nothing would work. I tried to turn the wii off, but it would not power down unless I held the power switch for a few seconds or disconnect the power. When I turn it on the eject works but the blue light is NOT on ... I hear the disk spinning ... but I can't get a signal. Nothing but a black screen. I figure there is some kind of hardware failure, but I don't know what, and I would like to find out in the hopes of getting and replacing the part myself. The wii is no longer under warranty. Can anyone help me with this problem.
