iPod touch 4th gen wont power on after installing new screen
So I was replacing an old screen on ipod touch 4th gen and I forgot to make sure the battery was dead so when I was unscrewing the shield for the board as I was unscrewing one of the screws I noticed a quick burst of electricity (I saw it actually). I went on to replace the screen and when all was finished it wouldn't turn on, hard reset, or even be recognized by itunes. I even tried shorting the third battery terminal on the right to no avail even while plugged in and holding power button. It doesn't respond at all to anything. Please help.
