II have a broken headphone jack.How can i fix it ?.

Step 1:
Your trusty iPod has been a close and reliable friend for a long time but one morning only the sound of air comes through the headphones. The likely culprit is a loose or broken headphone jack that is in need of repair. Rather than spend an exorbitant amount of money to have someone fix it you can easily make the repair on your own and have your iPod friend back. Read on to learn how to fix a broken headphone jack for a fifth generation 30GB or 60GB iPod video.

Open the iPod case with a small flathead screwdriver by slipping it under the centerline of the case. You will find a series of clips you have to release in order for the case to open up about an inch. Locate the headphone jack connection and verify that there are no broken wires. Fix broken wires quickly by twisting the wires back together and wrapping with electrical tape. Test the iPod for sound by connecting your headphones to the jack. Replace the wires completely if you find static coming from the iPod jack. Fold a business card twice so that it wants to unfold and slip it into the case over the blue sponge. This creates the pressure needed to hold the jack in place and allow a solid connection. Push the case together without engaging the clips on the side and test to make sure the jack is now working. Try a thicker business card or fold the first one again to get enough pressure onto the jack connection if the first card didn't fix the problem. Press the case fully together until the clips click into place. Use extra care when inserting your headset to ensure the jack remains in place.

Some keyboards use the amp output sockets for headphone use.
You might need some adapters for your headphones.
If it fell in, you would see an empty hole. This would be unlikely because it is held on by two screws. If all fails, buy an amp with a headphone jack input. Plug the keyboard into the amp and use the amps jack.

It might be the plug on the headphone that's bad - try it on another laptop. If it's the jack that's bad, then it will need to be taken apart and that's not easy to fix - recommend having a repair shop fix it.

Check the plug - it might have a broken wire, by wiggling it in the jack. It could be the jack as well - try another headphone in the jack.

See my tip on dodgy cable/jack on headphones. If the jack is different to the one shown, you should be able to get it from Maplin (UK user) or Radio Shack (USA).

The bottom case must be removed to access the jack and only then you can know what exactly was broken and how, or if , it can be fixed. But , most likely, is a bended jack, all it might need is some straightening of its contacts.

I would Try either http://www.ipodrefresh.com or http://www.ipodrecharge.com. They specialize in ipod repairs.

Yes, since the Headphone pin is stuck in the Jack, you are not getting audio from Speakers.

You should have noticed that connecting the headphones to the Jack will block the audio coming from the Speakers and the same is the current situation.

You can either try removing the blocked part using a Tweaser or get it repaired.
