make sure it's charged and the hold ins't on.(I know sounds stupid for my to say it but you'll be surprised) If that doesn't work contact apple service & repair.
try charging it or connecting it to itune
plug it in then leave it then unplug it, it should turn in then
Place it on the charger once its starts to charge it will automatically come on
It doesn't respond to touch, the screen is white, it wont turn on,
It needs charging.
