    Looking for electronic part.

    Today I tripped over the headphone cable connecting to my laptop. I severely dislike the location of the audio connectors of my laptop, but there's nothing I can really do about it. As well as bending the headphone connector (easily fixed), I damaged the audio jack of the laptop. This isn't a normal audio jack; it has SPDIF output as well as 1/8" stereo, analog output.

    Luckily, the audio connectors are on a separate PCB from the mainboard. I don't want to replace the entire audio PCB though, not when only this connector is defective. The connector only has 11 pins soldered to the PCB, so I want to unsolder those and install a new connector...if I can find it.

    Note the connector all the way to the left


    The manufacturer is Foxconn and on it is printed "7BGCA-TXL"

    Of course google doesn't turn anything up. Does anybody know exactly what this type of connector is called, or can shed some light on exactly what I'm looking for?

    Their search engine is a bit wonky. part number search doesn't seem to work at all, here's their type page.

    Can you check that link? It doesn't work for me, just a white screen.

    I was digging around my drawer and stumbled upon a pleasant surprise: no, not the mystery digital/analog output stereo connector, better: an unused gift certificate to bestbuy, with a balance that should be about enough to cover an external sound card

    digikey should have it if you can get through their search (sucks). If not, I have been very happy with one of these. I got mine online new for $11 a couple years ago. They also have a newer version, plus it does optical and analog (electrical) through the same plug.

    Since we're sort of on the topic. Any suggestions of where to get a tv receiver card that doesn't cost a small fortune?

    I'm probably going to get this:
    http://www.newegg.com/Product/Produc...82E16829102031

    I have never owned anything made by Creative, though there's a ton of literature about the X-fi. Out of principle, I try to support the smaller guys, which I did for my desktop PC. However, I can state with certainty that my local BestBuy stocks this item, and the gift certificate is in the amount of $50. I used my parent's netflix to get a few DVDs in the queue, so it's important that I get sound back fast to return those movies.

    My laptop had Dolby Home Theater on it, which I think worked a lot like Dolby Headphone. What I'm curious about is sound with this option enabled will be outputted in digital format via USB, or if I'll be reliant on Creative's CMSS-3D.

    Phantomcow, what about an old PC sound card you can rip one off of? Or perhaps even a dead laptop of similar make, if you can find one to get the entire PCB out of? An external sound card for a laptop just doesn't sound particularly convenient.

    I'm not too confident about being able to solder on just the connector, but you can certainly try. Stuff like that is usually machine-soldered on very precisely. It can be hard to match by hand, and there's a small risk enough heat will reach those tiny little passives right next to the connector to fry them.

    Woudln't hurt to try as he's got nothing to lose really. PC2's a hands-on DIY kinda guy, so I'm pretty sure he's handy enough with the soldering iron. As practice, I'd try unsoldering that socket first and see what's broken. Most of the connections would be grounds for the signal and shield anyway. Inspect the PCB very closely, you may have a cracked solder-joint or a trace may have been lifted by the twisting force.

    Did you see if the laptop manufacturer can supply you the whole board there? Shouldn't cost too much.

    I did buy that X-fi card, and it's great -- not any bigger than a flash drive. I use my laptop for maybe 1/4 of the year, as I have my much more powerful desktop at the house I lease for school.

    I'm pretty good with a soldering iron. Failing that, my friend is an electrical engineering student who works in a laboratory that does stuff like this. I don't see that any of the solder joins were damaged; my guess is that the damage is internal, perhaps with the prong that interfaces with the left side connector of the stereo plug. I can get it to work if I apply a directional force to the connector.

    Fortunately, Acer made the audio connectors a separate PCB. I can buy a replacement for 20-30 dollars, but that would be an admission of defeat . None of my old motherboards have connectors that are SPDIF/analog. In fact, I didn't even know such a connector existed until I bought this laptop; I've only seen toslink connectors :/. Thanks to all for the replies.
