Oh boy.. well, it looks like this wii might be done for. Anyhow, suddenly, yesterday, my Wii decided to stop booting up. It turns on, but the screen is black and there's no sound. I managed to format my sd card and then boot up bootmii, backup the nand (although it might be bricked...) and then format it. I still get the black screen. I looked through ribbon cables and everything should be in working order. I don't know what to do from here.
