Could be that we use 240v and yours is 110v.
OK, friends: I finished softmodding my wii, thanks for your help. The problem was caused by me when I wanted to take the power from the wii, I unplugged the wii from the console and then the power supply went down for a while. One should take it out of the wall AND console and leave it for a while. then it will recover again.
That is what I learned that past 2 days. thanks for all suggestions. I was also very happy with your guidance for the softmodding process. Much better than other I tried and caused many errors.
