My iPod touch will not turn on or charge. I've already tried holding the home and power button and it still does not work.
What you need to do is resetting your iPod. Hold down your down your home button and on/off button concurrently till the Apple logo shows up. Then, you will be prompted to reset your device. If this doesn't work then it could be hardware problem.
might be your USB cable
if you recently got the screen fixed or some other repair on it then it might have done what mine did. one turns on when plugged in.
Connect it to your computer, you might have to reset it
