iPod shows no signs of life, battery was replaced a year ago
I have an unresponsive iPod Video that's a bit of a headscratcher.
I replaced the battery after it began failing in December 2014. The head scratching began after reassembly, when the iPod would not recognize the 30-pin cable unless it was slightly pulled out on one side. If plugged in properly, no connection. Pull out the connector a little on either side, and the iPod would charge properly and be recognized by iTunes. I haven't been able to determine why the device only recognizes it's been plugged in when the cable is not properly connected. The device seemed to be working aside from this minor issue, so I figured it wasn't a problem.
The iPod continued working up until a couple weeks ago, when it suddenly froze. Before I could sit down and properly diagnose it, the iPod ran out of battery and it's been dead ever since. I left it plugged in overnight, but it shows no signs of life. I plugged it in while holding it to my ear, and the hard drive doesn't seem to be spinning. Normally I would assume the battery was dead, but since I changed it a little over a year ago it seems unlikely that the new battery would die so quickly.
Unfortunately, I don't have another iPod to test the components. Any advice? Should I just replace the battery again?
Update (01/22/2016)
I took a closer look at the battery connector, and it doesn't look broken. However, it does have some residue similar to that of a leaking battery. Maybe this is the problem with the connector? I've included a couple photos
Is this a good question?
