Your iPod may not be coming on because the "Hold Switch" is on or the battery is not charged. If is still doesn't turn on then, you may need to reset it. For more information, visit the support.apple.com website.
First yes if it show a itues app pic on the screen then you need to plug it to itues but if it is just blank sceen you probaly dropped it or try this first put it on the charger then after 5 mins keep it on still but now hold the power off button and the middle circle button for 3 min or untill it comes on. try it it worked for me.
