I have an iPod 4th gen that I replaced the screen on recently, and the bottom of the screen is not responding. I can slide the lock bar but barely. To make sure the screen was working properly, I put a new one on and got the same issue. I put the first screen on a diferent ipod and do not have the same problem so I know it is the ipod that is bad. I looked to see if there was any bent pins where it conects but it is hard to tell 100% if it is fine due to limited space. It does not look like any are bent. I did a hard reset as well and completely restored each a couple times to see if that would help but it did not. Any help or ideas would be greatly apreciated!
