Introduction: How to Fix IPod If It Won't Power on After Screen Replacement
If you replaced your iPod/iPhone screen and now your devise won't power on you may need to ground the battery. Here is a little tutorial on how to do it. I have successfully done this on several iPods.
Step 1:
Circled here is the battery terminal you want to ground. The rectangle metal part shown on the body is what you want to ground it against. **Make sure the iDevice is unplugged**
Step 2:
Take a small screwdriver & touch the battery terminal and metal housing at the same time to ground. You may see small sparks and this is fine.
Step 3:
Now plug in the power supply & you will see the Apple boot logo, (NOTE: Make sure both of the screen connectors are plugged in the back of the iDevlce and that no cables were torn)
