sounds like the screen has become disconnected, If she can still hear it making sounds etc, beeps and whatever, then it's that. if it's completely dead then she'll need to try a hard reset (power and Home button for 15 secs)
The ear jack could be faulty or it could be a problem with the docking port. It sounds as though your iPod is in docking mode. 1) Clean out the docking port area carefully to make sure there is no dust or lint jammed in there. Check for damaged pins, if you see bent pins then there isn't much you can do as the dock port is soldered to the main board and would cost you as much to replace the iPod as it would to fix the docking port. 2)If you are up to it, you can open the iPod and replace the ear jack. It is a small replaceable plug in jack so not a big job once you get inside.
HI Oldturkey, I know this is an old thread but hopefully you are still active. I have an iPod classic which will not charge the battery or sync. I have tried 3 known good batteries etc and have also checked the fuse and also replaced the Power IC. I have checked the battery connector and it seems solid, it is also receiving voltage to the battery connector. Before I go about replacing the notorious docking port, are there any other Mosfets or Diodes I could check that you can think of? There doesn't seem to be any corrosion on the board and it the ipod itself is in pristine condition Thanks
"silver plastic backing that you hold when you play it gets bent" what does this mean? Can you clarify. Are you saying the silver metal housing/shell/case is buckled bent or are you referring to something actually on the LCD screen? Thanks
The key to this is issue is removing the battery. When you remove the battery from an iPhone and then replace it. In most cases the phone thinks the date is 1970 Jan 1st. AT this point you will not receive a signal. The first thing to do is either manually set the date or to connect to wifi and let it set automatically. Then restart the phone with the sim card in and Hey Presto! You will get the signal back.
set date and time and restart phone. When you remove the battery and replace it, the internal clock reverts to Jan 1970. set the date manually or connect to wifi and let it auto update. then restart phone or toggle airplane mode a couple fo times to get the signal.
