So, Brie and I have been very happy with our Wii so far. It's awesome. But yesterday we started noticing something odd. Brie was playing Elebits when I got home and I quickly commented that there was some funny looking white static. Brie then said that it was REALLY bad in dark areas. She continued to play and I noticed what she was talking about. It was not so bad that you couldn't play the game, and maybe while playing it's not so bad, but for someone watching the game, it's horrible. My first thought was that it was the TV. We just got a 50" plasma and I figured it might be having some problems. So we switched the Wii over to our 32" CRT. Same problem.
Update:
Nintendo called me back. They said it was a problem they are aware of. They think the video cards are overheating and getting damaged. The only problem is that my Wii has never been in an enclosed space. It was under my entertainment center on it's side for a while, but the back fan was unobstructed. Also, I've started hearing about more and more people having this problem. This could turn out to be a big expense for Nintendo as it is a major "fix." I live in Seattle so I'm going to just take my Wii and get it swapped out for a new one (they have a machine that transfers all the virtual content and other stuff).
