iPod Shuffle 2nd Generation Troubleshooting
The 2nd Generation iPod Shuffle is Apple's first Shuffle to feature an anodized aluminum case offered in several colors and a clip for attaching it to clothing. Troubleshooting and replacing parts is fairly straightforward.
iPod won't turn on
No matter what you do, you can't get your iPod to turn on.
Hold switch on
Before delving into the guts of your iPod, check to make sure the hold switch isn't activated. If the hold switch is on, the iPod will ignore any input and refuse to do anything. If your iPod's problem isn't so easily solved, read on.
If your iPod won't turn on, especially if it has not been used recently, you may simply have a drained battery. Plug your iPod into your computer or AC adapter and see if anything happens. Ideally your iPod will recognize it has been connected to a power source and charge its battery. If it will no longer charge, it must be replaced. Replacing the battery requires soldering.
Bad control electronics
If absolutely nothing happens, it is possible that your iPod is not receiving your instructions because the electronic portion of the control buttons are bad. Replacing the control buttons requires replacing the logic board.
Bad logic board
If your iPod does nothing when plugged into a computer, the solution most likely lies in replacing the logic board. Transferring your old battery to your new logic board requires soldering.
No audio or distorted audio
Your iPod turns on and appears to work, but when you plug in headphones or speakers, the audio doesn't play properly.
It's unlikely your headphones or speakers are bad, but it's worthwhile to eliminate these as the source of your problem at the beginning. Try your iPod with another set of headphones or speakers just to make sure that the problem is with the iPod.
Bad audio jack
The most likely cause of audio output problems on iPods is a bad audio-out jack. Unfortunately, this jack is permanently affixed to the logic board. Therefore, you will need to replace the logic board.
Other issues that may hinder the operation of your 2nd Generation Shuffle.
Sometimes, a reset and restore will fix a sad iPod. Connect your iPod to your computer and use iTunes to restore the iPod. Restoring the iPod will erase everything on it, so make sure everything on the iPod is stored elsewhere prior to restoring. Sometimes it may be necessary to restore the iPod several times before it works properly. If you are unable to restore your iPod using iTunes, you can hard reset your iPod. iPod Shuffles can be reset by doing the following procedure: unplug from computer (if connected), move the hold switch to the off position, wait five seconds, then move the hold switch to either the play in order or shuffle position. At this point, your shuffle should be reset.
Bad logic board
If restoring the iPod didn't work, the cause is likely a problem with the logic board. There's not much to troubleshoot here. Basically, the only option is to replace the logic board.
One of the nice things about iPod Nanos is that their flash memory is nearly impervious to damage from dropping the iPod. Replace your logic board for new memory.
