Wires disconnected from motherboard?

Block Image

My left joystick wasn’t working so I disconnected everything to see because it felt like something was stuck but I couldn’t see the problem. So, I realised I would probably have to buy a new joystick. When putting the switch back together, I dropped it when screwing some screws back in and unfortunately these bits (I’m not sure what they’re called) has come discounted.

The one that has completely disconnected needs just soldering back on, I think?

While the other one is different as it’s the little white bit that has fallen off that houses the end off the wire.

Is this fixable?

I had no one else to do this for me & I’m not in a position right now to pay someone to fix it for me else I would have done that.

Hi Loran,

I agree with Alisha's answer in that yes, it could theoretically be fixed, but it's going to take some serious soldering and board rework skills to do so. Two of the solder pads have been torn off of the connector that's completely disconnected, so that wiring would have to be restored in order for it to work again. That means very carefully scraping the solder mask off the circuit board traces and soldering a piece of wire onto the bared copper then running it to where the pad used to be so the connector can be resoldered back in place.

In addition, the pads that are used for grounding and securing the connector to the board have also been torn off, so you'd need to both restore the ground signal and use some heavy duty glue to keep the connector in place since the solder connections will no longer be able to do that job.

Finally, the other connector will probably have to be replaced in order to work correctly, which will involve some fairly precise soldering skills, not to mention whether or not it's going to be easy to even find a replacement part.

Kudos to you if you feel you have the skills to tackle this repair; I might try it myself, but then again I've been working with printed circuit board for 40 years now. Otherwise, my advice would be to simply replace the circuit board. iFixit doesn't have a guide specifically for replacing that board, but the Left Joystick Replacement guide has that board being removed as part of the procedure, so if you just follow the guide and stop at Step 27, that'll be exactly what you need.

The board itself isn't all that expensive; I found an example on Amazon for only about $10 USD; there are many other places you can find them such as eBay and AliExpress among others.

Personally, for the money that's the way I'd go rather than taking a chance on a repair that only has a moderate chance of success.

Good luck; let us know how it turns out!

Update (05/31/23)

P.S. I neglected to mention this, but the part you need to replace isn't actually considered the motherboard, rather most sites are calling it a daughter board, as it's separate from the motherboard and, more importantly, much much cheaper.

First of all. We’re all on this fixing train together and sometimes “oops I dropped it when I was trying to fix it,” is part of the journey. You endeavored to fix the thing and that’s admirable in and of itself.

Secondly. Yes This is for sure fixable. The one that’s torn off, as you said will need to be secured back down and any solder connections will need to be remade. The other one, you could also replace (which is preferable for longevity’s sake) or you could try the cruder method–put the cable in the connector and tape down so it stays. Or add whatever is necessary to make the cable stay connected (little shims sometimes help). That’s a little harder to do on these style connectors, but you might be able to make it work.
