iPod won't power on after screen replacement, even when plugged in

"If you get problems powering up after screen swap, locate the 3 battery terminal beneath the metal cover. Refer to the battery replacement guide to see what the terminal looks like. Find the +3.7 volt terminal using a multimeter (From memory, it's the one on the right as you look at it.), and short this terminal briefly to ground. (The metal plate surrounding the home button will do.) Then, plug the phone into a charger, and within seconds you should get your confirmation beep and the screen should show that the phone is charging. Wait a minute or so, and it will boot up.

This has worked for me on more than a few occasions. I hope it helps"

"Here's a tutorial with pics that everyone has been requesting. I've used this method over a dozen times successfully. Good Luck!!

There are 3 small battery terminals (shown below). You only want to touch the one to the far right (circled below). Avoid touching the other 2 terminals!!"

What actually happens is when u don't turn off ur iPod before changing to the new screen the circuit board shuts down. But only temporarily the easiest way to fix this problem is to put it up n let it die Completely. N be patient it will take a while depending on how much ur battery was on and I know it works from experience it happens to me 3 times already my battery was at least at 70 percent and it took from 7pm to at least 4pm for it to die. If it's full wait at least 2 1/5 days then plug it in n it should be charging within seconds if that doesn't work then ground it

"so ive been fixing an ipod touch 4th gen and had this exact problem. i replaced the screen. turned it on and got a white screen. turned it off then no matter what i was stuck with a black screen. i tried all the trick above including grounding, hard reset plugging the charger in ect ect ect. nothing worked.

please note that my solution will wipe all of the data and reset the ipod completly.

what i ended up doing was plugging the ipod into the computer. i tuned did not reconise it and the screen remained black, i then put the ipod into dfu mode (power button for 3 seconds, power button and home button for 15 seconds, then the home button for 5 seconds.

itunes then recognised the ipod, note that the screen remained black.

itunes downloaded the latest firmwhere, and began the restore process. the ipod screen remained black until it began to reset. the apple logo with the loading bar appeared and once it was completed th ipod was working again,"

I GOT IT!! 1. connect the LCD cable 2. try to turn it on before sticking it down. 3. if black or white screen do a hard re-set, this can be done by pressing and holding the home button and the sleep/wake button on the top
