If you were wonderingHow can I change the headphone jack? Well, here we will explain in detail, so as not to fail the test. To do this, you will need to have basic knowledge, but we will explain it to you so that even if you have no idea, you can do it.
Headphones are one of the things we damage most often, however they are often due to simple and easy to repair things, such as the plug. In some cases, the hearing aids are not damaged, they simply need a little charge, this happens especially in Bluetooth headsets. This is why it is important to take a good look at your hearing aids before trying anything.
What are the most common reasons why the headphone jack no longer works?
Due to the constant use of headphones, they are prone to rapid deterioration. Mainly those that are not of good manufacture tend to be damaged because their materials are cheap and easily damaged.
However, even the most expensive headphones can be damaged, but all of them can be repaired without major complications. One of the most common reasons why the plug is damaged is when it is bent when using your mobile phone. This is very common when we are used to using them with the mobile phone in our pocket, because the constant movement weakens the plug and can make it bend. In the most extreme cases, the plug may get stuck in the device.
In addition, this may cause the cable connected to it to be cut and fractured. In these cases, it is common to hear only one headset instead of both. Fortunately, changing the file is not that complicated, but you will need to have some basic materials to do it.
What materials do I need to change the headphone jack?
Mainly, we will need a cutting tool to help us remove some of the broken cable. In addition, we will need sheet metal, soldering iron and a spare plug to make the change.
Procedure for correct change of headphone jack
Before you begin the procedure, it is important to have a clean cloth and a little alcohol. You will use this to clean the area of the cable that we will cut in addition to the old connector. You can also start by cutting the cable at a distance of 2 cm from the original connector.
Later you will need to unplug the cable so that its cables are exposed and we can identify them correctly.
Identify the cables
When we have separate cables, we will have to notice their color, depending on the headphones you have, they may have one color or another. This is because, according to the manufacturer, these changes, especially in Chinese headphones. If you have original headphones, the colors are: gold for negative or ground, red for the right channel or right headphones and green for the left channel.
If you have a headset with an additional blue cable, it will match your microphone.
On the other hand, if you intend to repair Chinese headphones, you will need to have one continuity tester. This is because these colors are often random and not governed by a specific color. When you have the tester, you will need to put on the headphones first, then test the continuity between a pair of cables. When you play the correct ones, you will hear a small sound in one of the headphones, indicating that this combination corresponds to that ear.
Something you should keep in mind is that the ground (gold wire) is split, so it will be connected to both the right and left ears. For the same reason, we will find only a ground wire.
When we differentiate the cables, we will have to go to the Jack connector it is usually metallic and to open it we will have to unscrew it. This will show us three pins of different lengths. We can guide you through this to know which one corresponds to each cable.
We will start with the shortest pin, it corresponds to the right channel, we can mark it with a color to identify it. The next one is the middle pin, which is the one that corresponds to the left channel. Both pins are close, so it will not be difficult to see them, in the end we will have a much longer pin, which ends in two ends.
This corresponds to the ground of the circuit, ie the golden wire.
Place them correctly
When we have the identified connectors and cables, it will be time to weld them. For this we will have to use soldering iron and a little tin. In principle, we will need to connect the soldering iron and, while heating, place the cables in their respective connectors, through a small hole that each has.
Then we will have to rest the soldering iron on the pin and approach the tin with the other hand. so as to rely on the cable and attach it to the connector. The higher the quality of the tin, the faster the process will be and we will see how they come together. We will repeat this with the three connectors and disconnect the soldering iron. When you find the plug, the most common is to find a small plastic, it will need to be placed on top of the connectors so that they are insulated and do not touch the housing of the equipment. Finally, screw in the connector again and it will be ready. To test it, you simply need to connect it to a computer or mobile phone and play music. If you prefer, you can use apps like Spotify to do this check.
What can I do if even changing the plug, the headphone input does not work?
If you changed the plug and the problem is not yet solved, then the problem may be related to the horns of the headphones.
However, this is rare and you don’t see it very often, so check the joints you’ve made and see that there is no contact between the wires.
If you are not sure you can use heat shrink on each connector to make sure they do not touch or cause a short circuit. Its use consists in placing the insulation on the cable and then bringing it to a heat source, whether it is a hot air gun or a lighter. This will contract and insulate the wire.
