Ipod touch screen will not work

I couldn't get mine to turn on either.  Finally looked up the manual on the Apple site.  They said to reset it by holding both the start button on the front of the iPod and the turn off button at the top.  Push them both in at the same time and hold for 10 or more seconds.  They also had a way to get started if that didn't work but it resulted in erasing everything that had been added to the iPod and starting over.  I was happy that the first method worked for me. Hope this works for you.
