Mp3 player repair

This is likely an issue with a loose connection in the jack in your player. If it is still under warranty, then you should be able to get it repaired or replaced using your warranty. If it is not, and you are not VERY mechanically inclined ... you can take it to a professional to get it repaired ... but depending on the cost of the unit, you might just be better off buying a new one than paying to have it fixed. If you ARE very mechanically inclined, and the unit is no longer covered under warranty, you can check the jack's connections and fix the loose one (if one is loose) or try replacing the jack inside the MP3 player ... but this is not as easy as it sounds due to the small size of the circuit boards and their sensitivity to heat (you will probably have to use a soldering iron, which can easily overheat a circuit board if you are not REALLY good with it).
If paying to have the unit repaired is not going to be worth the cost, and your unit is no longer under warranty (so it doesn't matter if you break the player, considering that your only other option is to buy a new one anyway) then give the repair a shot yourself -- the only thing you have to loose is a broken MP3 player. Open the unit up and find the headphone jack. Use a voltmeter to check the connections from the jack to the circuit board -- if those connections are good, then you have a bad jack. Go to Radio Shack (or somewhere similar) and get a new jack that is exactly the same as the one that you have in your unit. Use a soldering iron to loosen the connections from the circuit board to the jack (to avoid overheating the board, only touch the soldering iron to the soldered joint for a second or two at a time until the solder holding the jack in place JUST melts enough to pull the connection apart. Then, after giving the unit a while to cool, install the new jack with the same technique. Hopefully, you can get the new jack installed without harming the other circuitry, and you should be good to go. If anything goes wrong, the unit will probably not function again ... so make sure that (unless you are used to doing this type of work) this is your LAST option before buying a new MP3 player. Of course ... if it works, you will have every reason to be proud of yourself for being able to do it (and you will have confirmed your skill with a soldering iron). Good luck!

If you know anyone with soldering capability the pads on the headphone jack just need to be re-soldered. Mine did the same thing so I re-flowed the solder joint and now it works perfect.

Most common cause is that the solder connection that holds the headphone jack to the board is broken. Usually can be fixed by taking the player apart and re-soldering the connection. Takes some effort and a pencil type soldering iron.
The T10 headphone jack is underneath the main board and you have to undo a solder connection in order to remove the board to gain access to the headphone jack. It's a lot of work but it can be done.

your headphone jack is loose if you take it apart and solder it back it will work fine.

you have a loose connection on your headphone jack, need to solder the jack back in place.

you will need a very small soldering iron (pencil) and solder and solder the jack back on the board

i had the same exact problem with mine. Reading around it seems to be a common problem with the Sansa line. I opened mine up and found that one of the solder points that holds the ear phone jack to the main board had come loose. I soldered it back and it works like a charm. Pretty easy too. If you have a soldering iron, just open it up and resolder the solder point that has broken off. You can read instructions for disassembly here: http://www.anythingbutipod.com/archives/2006/11/sandisk-sansa-c200-disassembled.php When you have it apart, looking at it from the side, with the jack to the right, the broken point should be the rear (closest to the circuitry) point. You will see a very small, not sure what to call it, chip on the board you have to solder a connection to. here is a diagram: http://i42.photobucket.com/albums/e321/fuzzygoat/sansa-c200-disassembley-8.jpg Hope this helps.

Although headphones jacks are convient. They are very delicate as well. It take very little pressure agaist the jack when plugged in to bend the pins inside the jack that makes the connection. Then they get temermental. Generally the only recourse is to replace the headphonejack in the unit. better left to the techs. replacing can be tricky. But just to make sure you say you have tried other units. Here is something that works once in a great while. Unplug the unit dip the headphone jack {the tip on the headphones} in rubbing alchol insert it in the jack on the unit and spin it repeat several times let alchol evaporate then stick jack back in unit an spin again. Plug unit back in and see if it is better or the same.

Loose headset jacks are a very common thing and sometimes easy to fix. First thing make sure you know how to take apart the device as they all dont have screws as some units have snaps and you dont wanna break them. If you do get it apart, see if the solder connections are loose or broken. If you know how to solder then touch the solder iron with a bit of solder and let it flow only on the one tab. Next resolder the other two as there are usually three terminals. If the flex board or printed curcuit board seems to come off with it then your gonna need to run a small(26-28 gauge)wire from the jack connection to another part of the PCB thats along the same line as the terminal. If all this is a little frightning then take the unnit to a pro as this is a minor repair MOST of the time and should'nt cost much. Good Luck
