I tried all the steps to reset my nano 6th generation and it still won't turn on. What do I do then?

I tried all the steps to reset my nano 6th generation and it still won't turn on. I've had this since February and just started having problems about a week ago after I charged it. Now I can sometimes get it to turn on but mostly it just stays off, I can't even reset it with it plugged in. I have noticed that it get really warm to the touch when it's plugged in and if I let it cool down I might have some luck but soon I have the same problems.
