Sanyo flat screen

I bought a 27 inch sanyo flat screen tv not quite a year ago for my 16 year old son. I unplugged it today to put a new faceplate on the outlet, when I plugged it back in it wouldn't come back on. I have done evevrything I know to do, gone through the book , troubleshooting, etc, and still nothing, even tried another outlet, nothing, and of course it is no longer under warrenty. Can anyone help me please?
