My ipod 4g is stuck at the battery with a lightning bolt underneath and won't charge

My iPod died about a month ago, and I waiting. I tried charging it with almost everything I could. I plugged it into the wall, computer, etc..

To make this easier, my iPod is not jailbroken and the home button fell off and I had a feeling it had to do with the orange chip underneath the home button being loose, but that's not what other people who experienced the same thing as me had.

I tried pressing the power button, holding the power button. I can't use the home button since it is broken. I always used Assisitive Touch.

I tried pressing the power button over and over. I left the iPod in each section I charged it at for at least a night, hoping that in the morning it would turn on again.

Because it won't turn on, my iPod won't register in itunes so I can't restore it or recover it in any way that I know of without using itunes or the home button.

I eventually gave up on it and recently came back to my iPod, wanting to use it again.

I would really like to know how to fix it.
