Ipod 5th Generation does not turn on and does not charge.

Hello,

I have a Ipod 5th generation video 80gb and it will not turn on and will not charge with a good working cord. I have made sure that the hold is not on and that the ipod has had no other problems before this. Battery was work just fine and would charge before this problem. Now when I plug in the cord the ipod does not do anything, does not charge and does not turn on. I have tried the 'push down the menu and center button at the same time' but this has done nothing. Tried holding down the buttons for five minutes with the cord plugged in and without the cord plugged in. I was hoping that there might be a trick to make it turn on. I think that the logic board may have fried but I do not know how to know if that is the problem. This ipod does have the original memory card in it and I can not hear it turning inside, can not feel the vibration of it working as well. This is why I think the problem might be the logic board.
