Yes I was going to say to try that out! Don't just toss it and get a new one- at least call Nintendo to see what's up. When my husband's XBOX stopped working (we hadn't even had it for one year) we called Microsoft and sent it in and we ended up getting a new one cuz they couldn't fix it!
My friend got an XBOX 360 for $50 when they FIRST came out cuz some guy who bought one after a month it stopped working and he gave it to my friend for $50. He called microsoft and they fixed it for FREE! If that guy had just called he would have saved himself a ton of money!
Don't just give up- exhaust all the other options FIRST
