Wii wont power up - Nintendo Wii Console

the Wii power brick will go bad, try having someone bring there's to your house, and if your Wii works buy a new one
Shop Nintendo Nintendo Online Store

i would try resetting the wii s power supply by unplugging it from the wall and wii for 5- 10 minutes

Unplug the power supply from the wall, and from the Wii box. Wait a few minutes. Connect power supply back to the Wii, plug it back into wall.

Did you remember to plug the Wii in at the wall? If not, you are mentally handicapped... TO BE CONTINUED...

u broke it just replace the power cord or wii

Mama Mia Mama Mia No Your Power Of Da Wii Ain't Turnin On Buy A New One (Nagetive)

try using another power cable

it might sound silly but is the power cable pushed all the way in? if so take your wii to game or similar and ask them to test with their cable on pretence of poss buying a new power lead if theirs works then new lead is what you need

If you have pressed the sync button on wii, then on the wii-mote, and it still didn't sync, try unplugging the Wii console for few minutes and try the process again.
There is another syncing mode, but you have to have at least one wii-mote connected to the wii. You press the home button and the click on the wii-mote on the screen. There will be a reconnect button. Press that and then press both the 1 and 2 buttons on the wii-mote[s] you want to connect. This is the ONE TIME ONLY connect mode, used when playin on a friends Wii. Once the Wii is powered off, the wii-mote wont be connected any longer and will still be the default wii-mote for your wii system [not on your friends]. Hope this helps.

make sure your light bar is plugged in and in sight
