I had too. I didnt want too but didnt want to deal with it any longer. I have to send my wii in. the games work, the controllers work, but the biggest problem is that when i try to shut the wii. If i try to shut the wii using the wiimote, the wiimote shuts off, not the wii, if i press the power button on the wii to shut off, it doesnt or there is a long delay. I have to unplug it to shut it off. It also once in a while makes weird cracking noises. I am sending it in to nintendo, everything is set... But im concerned that nintendo wont see the problem. I dont want the wii to come back and have the same problem. So for the people that have sent it back, do they fix the wii? do they usually find the problem? im pretty sure something is wrong and i just hope they find it.... i have also had times when the wiimotes losses connection to the wii. its the wii, im positive its not the controllers.
