Sansa e200v2 headphone jack repair

[j8048188]

Hello all,
I have had my e280v2 for over 2 years now.  It's been great until a couple of days ago, when I lost sound output in the left channel of the headphone jack.  Is the same repair procedure as the e200 used?

Thanks,
J

I have never actually inspected a v2 e2xx player, but I believe that the same part is used for the headphone jack.  If the part is the same then the repair process should also be the same.

In any case, replacing or repairing a jack like this is generally a pretty similar process.  If you wish to repair then you should look for pads that have detached or breaks in the path and then find a way to repair the pathway or wire a new one to a suitable point on the board.  You should probably look into using some epoxy for structural support, since the v1 e200s have been prone to this due to relying on the electrical connections to also provide structural support.

Well, It turns out that the actual post on the bottom (left channel) is actually broken.  Does anyone know where I can buy a new jack or the part I need to replace?

Depending on where it's broken you might be able to solder a short length of wire to bridge the gap.  Maybe someone else can provide a part number for you.  Alternatively, you could bid on a broken player on eBay or similar and get the needed part from that. 

Good luck!

After some probing around the player, I found out that the left channel is not outputting any signal at all.  In the OF, I do get a left output thought the dock, so I don't think it's the processor itself.

Any suggestions?

That thread from the Sansa forums helped me with repairing the jack, the problem you have is actually kinda common and involves soldering/taping down a loose connector in the main board. Hope this helps, for if you go to page 2 you'll have solderless options for repair.

It's not that, I'm not getting any signal to the jack.  I have done some probing, and no sound is being output to that trace.  I'm using an e280v2, so the player is slightly different and does not have a daughter board. (if it did, i would buy an e250 and swap them out.)

Any corrosion or evidence of breaks upstream on that trace?

[j8048188]

I can't see any, but I can post some pics within the next week or so.  I am looking to find a cheap e250 and use my 8gb microsd card with it.  My battery is still good, so i wouldn't even mind buying one with a bad battery if the price is right.

Looks like this post has been dead for a while, but I've recently come across the same problem.  I've got decent soldering skills so I opened the unit up and couldn't find the usual breakage. 

I got the continuity tester out and confirmed a solid connection and even traced it back a ways.  Fired up the oscilloscope and I don't seem to be getting any signal to the left output, and I think the right levels are lower than usual. 

Anyone familiar enough with e200v2 line to know where the problem likely occurs?  Could a shorted set of headphones have blown something? I seem to remember a bad pair a bit ago...

I've never plugged a bad pair of headphones in.  I just ended up buying an e250 for $20 locally and installing RB on that.  My other one is still here if someone wants it for parts/troubleshooting.
