My left headphone of my ipod is not working anymore what can i do to fix this ?

Damaged hardware is responsible for the most obvious iPod sound problems. In such cases, Apple may be able to help you fix the problem, depending on the status of your warranty.
All iPods have a one-year warranty according to Apple's website.
Software problems can also affect your audio.
For example, downloading a non-certified Apple application can stop your sound from working correctly.
Returning your iPod to its original factory settings fixes many of these software glitches.

Plug in a different set of headphones and test the sound.
If that set works, your old headphones were the cause of your audio problems.

If your iPod still doesn't work, proceed.
Remove an application on your iPod Touch if you installed it right before your sound stopped working.
Hold your finger over the top left corner of the application.
It will shake.
Touch the "X." Touch the "Home" button.
Restore your iPod to fix other potential software problems.
Open iTunes. Plug the iPod into your computer with a USB cord.
Click on your iPod on the left-hand menu.
The iPod will be listed under the name you assigned it when you first set it up.
Click the "Restore" button on the menu.
Leave the iPod alone while it restores. It may take several minutes.
Test the sound once the restore is complete.
The iPod syncs after restoration.
Once the sync is complete, the process is over.
Contact the Apple Technical Support line at 1-800-275-2273 if your audio still doesn't work.
Have your iPod with you.

This is a common problem with the headphone jack - if you google "ipod 30Gb headphone jack repair" there are both places that will replace the jack and places that will sell you the new "ribbon" connector and hold switch and jack (it's all one unit). If you're comfortable opening the iPod and have a TINY (#000) jeweler's philips head screwdriver you can replace the unit with no soldering. It helps if you have patience and small fingers and good light; you'll have to fasten the ribbon connector carefully. I paid under $10 for my last part but I've seen the same part for $30+, so caveat emptor. For that price they should put it in for you...

It's more than likely a small wire that has snapped inside the cable due to stretching it's probaby not worth fixing as the wires are very small and delicate ,nowadays people just buy a new set of headphones.John

I'd say something is wrong with your headphone jack on the ipod. I would contact the apple helpline and make them help you.

The problem is the internal headphone jack has malfunctioned. To fix the problem first try doing a hard reset, then update your ipod with the newest version for it. Also try blowing it out with canned air. If this does not work and you are still under warranty schedule an appointment with a genius at your local Apple Store. If you don't have a warranty then order an internal headphone jack online and install it yourself, because apple will charge you more than your ipod is worth. Make sure you order it for your model. You can go to youtube and find tons of tutorials on how to install the jack. So good luck. This is a very common problem with ipods and is simple to fix with the right parts.

HI,
I actually had the exact same problem with my ipod touch. It's actually not a problem with the headphones but with the headphone jack on the ipod. For a while i "solved" this problem by wrapping my headphone wires twice around my ipod [so it was tight and the sound could be heard, the same way u do it by pushing it with ur finger]. Well one day my ipod jack just fixed itself, I got lucky. But my advice to you is to send it into apple like my friend who had the same problem did, they sent him a new one [hopefully u have a warrenty!]
hope that helped!!..thank you!!..

This is either cause by a damaged headphone socket in the iPod or a loose connection. The only way to solve it will involve opening the iPod case and inspecting the daughter board that the headphone socket is on.

headphone jack needs to be resoldered.

The headphone jack on all the apple products have issues (even their laptops). There is no easy fix, other than having the jack replaced, or remounted. A common issue is that it comes loose from the pc board, especially with the movement of the headphone cord. This is a design/functionality flaw.

Hope this helps some.
