Sure looks like some fried components indeed. I'd say, pop the thing open (if it's out of warranty, that is) and check for a match-like or plastic-burn smell. Check if components can be replaced relatively easy (ehm, As far as I know that would be just the dvd-drive or nothing at all, in case of a wii) and find them cheap on ebay. Otherwise, off to the store for a new wii you go, because this most likely isn't a software-based brick!
