Chosen Solution

i replaced the lcd / digitizer on the iPod because it was cracked and the iPod touch worked completely fine before now i have the screen all hooked up and nothing shows up on the screen and it won’t show up on my computer and i checked that power/volume flex cable and everything looked fine

Your ipod would still show up on the computer with a bad flex cable. Try holding the lock and home buttons for about 15 seconds and see if that wakes it up. Did you use an online guide to replace the screen?

Israel, It sounds like it is a bad screen. Check to see if the connectors are bent in any way. Every once in a while some replacement screens are just DOA when they arrive. Hopefully whoever you bought it from will send you a replacement.

I work at a cell phone repair shop, we fix ipods as well as iphones. And every 4 or 5 ipod 4th gens that come in, this happens to one. What you need to do is put the ipod into DFU mode and restore it. Not sure why this happens, but that’s the cure. Enjoy!

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!! see the pics http://guide-images.ifixit.net/igi/YiaQuhttp://guide-images.ifixit.net/igi/AnevP

Thanks for the info. One thing still troubles me, when the oem (cracked) screen is plugged in everything works fine, but when the replacement one is installed nothing will even power on. iTunes won’t recognize it. BTW this is the 3rd screen I’m on (seller has been great) I spoke to someone that said these iPods will rarely not accept aftermarket screens, any thoughts on that? Thanks very much for sharing your knowledge.
