Is my wii brick?

Today I was playing Mario Galaxy and the game just froze.
I had to unplug it to turn it off. Now when I try to turn it on the light goes green, I can eject a disk but the controller are not syncing (or working) and I get no signal on the screen.

I'd like to know if have a full brick. When people talk about a black screen, what do they mean by that? No signal? or there is signal but the screen it's black?

Thanks.

Sounds like it could possibly be a broken bluetooth module. Can you turn on the Wii with a remote, or do you need to use the button on the console? If the later, its almost definitely a broken bluetooth module. I don't know how hard/easy these are to replace.

do u have any homebrew on the wii?
