How to repair a 3.5mm jack socket Solved

Question

Hello,  I have a problem with my audio headset (Razer Barracuda 5.1): there was an increasingly troublesome short circuit on the green (stereo) jack for listening to music. After consulting the manufacturer, who doesn't sell the adapter for my faulty jack, I researched various forums and acquired different models of jack connectors in advance. I cut off the defective jack, expecting to find 3 or 4 different wires, but that wasn't the case: the outer cable was black, and it only contained a single red wire. I stripped it back 1cm thinking it protected other wires, but that wasn’t the case. There was only a copper braid and a few blue/black wires, no thicker than the copper wires.  I'm completely lost and fear I may have to give up on my headset. Does anyone know what type of jack this is and if it can be repaired?  Thank you very much in advance.

Debriefing of the operation:  I stripped further down and I was wrong: there were three "colors" of wires:  - the "natural" copper - blue ones - red ones  All these beautiful people fully stripped and without plastic coating: a pain to sort them out. I would be curious to know how it was soldered on the original plug. Another strange thing (I am a novice in this field, it might be normal you would say): the blue and red copper wires are "colored", not covered in a plastic sheath: even when I pass them over a lighter, they retain their color!!??  So I sorted the colors and soldered them onto my new plug: all good, it works even if my soldering is anything but professional.

Hello  Could you send us some photos (wires, new jack)?  Do the wires have some sort of coating? If so, it needs to be burned off with a lighter; this layer of paint is meant to replace the casings that insulate the wires and thus prevent false contacts. I've seen this for a few years on certain headphones, often of a specific brand.  Photos would be useful; I've liked this kind of tinkering since I was a kid, it could help.

Hi   In a 3.5 mm jack, there aren't 36 connections, there are 3  start by stripping your wire properly.  you should find:  The shield > that's the ground  then two other wires (regardless of the color) that correspond to the positive for the right and left channels  You can either buy a 3.5 mm jack and solder your wires into this jack (the ground is soldered to the longest pin)  or retrieve a jack from an old cable in your possession that you cut and strip.  if your retrieved jack has two wires, strip them and connect the shields together and the colored wires together      -- Keep us updated      Regards

Hi there,  I had already bought two models of jack plugs before since I didn't know what I'd be dealing with (3 or 4 wires depending on what I had read). And I took another look at my "bundle of wires" (I don't know if you've seen the picture), I'm certain, there is no "electric wire" as such: the tiny copper wires were surrounding about ten other bluish wires that were just as small: no "real wire/electric cable" to solder onto one of my new plugs.  I'm not any further along.

re  if I see correctly in the picture  there are 3 types of wires -the bare copper -the black ones -and the blue ones tell me if I’m wrong, you separate all these wires to group them by color even if they are grouped in pairs (blue black)  -- Keep us posted     Regards

SierraNovember47 · Answer

You see well. The problem is that each of the colored wires is as thin as one of the copper wires forming the braid (about 1/10 of a millimeter, I would say). After re-examination under a magnifier, I counted 5-6 blue wires and just as many black ones. I tried to burn them a little and they indeed turn copper color. I will try to group them and solder them onto the connector.  However, aside from the copper braid wires that are most likely the ground, for the other two colors, it’s going to be guesswork! I hope it won't damage the helmet if I reverse the polarity. If anyone has any advice, I’m all ears.  I’ll keep you updated on the progress ...
