I have the exact same issue (down to the nephews playing on my wii while I was outside). They put a black ops disc in and started it up. It never went anywhere apparently, just went to a black screen. That is when I came in and turned it off. My wii boots fine except that no remotes will sync(tried 5 so far). I have tried every method that the search function (and google) has provided. So does a bad bluetooth always black screen or does anyone have any idea what might be the issue?
