You need to sync them again. To do this you must first press a little red button located in the front of the wii next to the sd card slots. Hold down for about 2 to 3 seconds. Right after wards look on the back of the wii remoter and take of battery cover. Press the tiny red button on the bottom left hand corner to sync to the wii.

Trying to turn xbox on and getting blinking red ring around power button


If you are having three red lights flashing around the power button with upper right corner not flashing, it means that your Xbox 360 is having a general hardware failure. This is caused by the internal components of the console experiencing a malfunction. You can contact Microsoft Xbox Support for it to be repaired.
