Why is my Wii not turning on?

Hello, this is my question, so my cousion jammed a disk in the wii. I got it out, and as I was. It turned on. But I went to go re-hook it up in the tv and plug it in. And the button was red like power went through it. I Clicked the button, then it wouldn’t turn on. I do remeber using a knife to get it out. And my friend said I may of scratched the motherboard. I need some help here. Please.
