It's not a black screen of death. A BSOD would be complete black without sound or any form of picture, a corruption to the actual System of the Wii which makes it totally inoperable.
I'm guessing here that this is some kind of TV signalling issue, where the Wii is putting out a signal your TV can't display.
If you can get the Wii to connect to your TV in another way then you may be able to see it. It could be your Wii has reset itself or something. I use composite cables myself and have no idea how you set the Wii to use Component.
