Broken Nintendo Wii, need help.?

I've had the Wii for a little over a year (Dec 25th, 2010 to be exact) and it wont turn on, nothing is responsive, I've tried changing outlets for the plug and un plugging it and hold down the power button for 30 secs- 1 min. not sure what else to do. Anyone with knowledge of this to give me a hand would be greatly appreciated. Thanks.
