Odd.
Perhaps you should consult Nintendo. Wait for a while first though so people with more knowledge on the subject can post, as all I can suggest is the same as I said to Soriku (who had white lines), which is to try re-plugging the Wii to TV cables as they may have been knocked.
I would guess this isn't the same problem as Soriku though.
