It turns out I have a defect Wii (black screen when trying to start channels, discs not recognized) and I'll have to replace it.
Does anyone have any experience with the replacement/repair policy of Nintendo Benelux? I can't contact them now because of the holidays, but I suppose I'll have to call them, ask for a replacement and send my defect Wii to them. If anyone has had any experience with sending defect consoles to Nintendo (Benelux) and could enlight me on this matter, I'd appreciate it very much.
