My Wii started acting up. When I look at the menu or any games, the screen is quite bleached. The problem is not with the brightness. In fact, when a new screen comes up, it looks fine. Then, suddenly, everything is brighter than it should be, creating a very washed-out look. I checked the Nintendo web site, but there is no mention of bleached displays. Has anyone else had this problem? How did you fix it?
