I was trying to install the Wavebird board inside of my wii on controller slot 1. It took a while, but I got it installed and everything. So then I go to turn on the console. I plug it in and the yellow light comes on (I had WiiConnect24 on). I press the button for it to power up, and the light turns green, and the slot lights blue, then the green led quickly turns red and it powers off completely. It's not booted long enough for video to even output. This is reproducible. I suspect I might have shorted the GC slot 1 with too much solder. In the gamecube version of this mod, you just had to unshort everything and it worked. Will this fix the wii as well? Or is something else the culprit? Worse case scenario I'll buy a new wii, but if it's something simple, well, obviously help me before I spent $250 pointlessly.
Update: Shorting the GC port on your Wii will cause it not to boot. However, if you simply unshort it, everything is fine. The Wii does a check on start up and turns off instantly. Shorting your GC port does not permanent damage to the Wii.
