What to do if the headphone jack is in poor contact, and what to do if the computer headset jack is

It's not a problem with the headphones, it's a problem with the machine, the line is in poor contact, and it needs to be repaired.

1.How to deal with the poor contact of the headphone jack.

If it is a stereo socket, the conduction principle: the three segments of the stereo plug from the beginning to the root are the left and right channels and the ground wire; The socket is a steel plate structure, when the plug is plugged in, due to the protrusion of the three sections, the steel sheet is in contact with each part respectively, so as to conduct the left and right channels and the ground wire.

One of the reasons for poor contact is due to the poor contact between the steel sheet and the fixed contact point, the solution: use a large steel needle or similar tool, reach into the socket to adjust the bending angle of the steel sheet, and keep inserting the plug to see if the contact is improved; The second reason for poor contact is the open welding of the solder joint of the binding post, the solution: open the casing, observe whether the solder joint of the circuit board socket is welded, if it is repaired with a welding gun, there is no welding gun at home, and the hot melt adhesive will be used to fix the solder joint of the adjusted contact, but this is a temporary solution, and a welding gun must be used to completely solve the problem.

Satisfied, ** points.

2.What should I do if the place where the computer is plugged into the headphones is not in good contact.

If the computer headphone jack is in poor contact, it can be dealt with as follows:

1.First, handle the earphones, wrap the earphone plug with a paper towel, rotate and wipe the earphone plug several times. It is enough to achieve a bright surface.

2.After dusting the headphone jack, prepare a cloth and a small screwdriver, which can be replaced with something else such as a longer bamboo skewer.

3.A cloth is wrapped around a screwdriver and then tied with a common rubber thread with a wire inside it to make a tool to clean the dust from the holes.

4.Gently wipe the inside of the headphone jack a few times. If you have alcohol, you can also wipe it with a small amount of alcohol.

5.Then there's the use of scissors. Looking through the jack, you can see that there is a metal piece inside the earphones. Use small scissors to gently scrape on it once or twice. You can also clean up dust, but don't break the jack with too much force.

6.If it is elastic against the headphone plug, the metal sheet elastic fails, and it is more troublesome. You can use a small needle to pick up the metal piece a little, which can have a little effect for the time being. If the space is too small to operate, you can only change the headphone jack.

If the earphone plug is not in good contact, you can cut off the broken wire, re-strip the wire, and then re-connect the plug to weld according to the color of the wire. Or buy a new plug, in the order of definition, left, right, ground, wheat, corresponding to the color of the default line welding, left green, right red, the bundled with rubber wire, separated out is the positive electrode of the wire control microphone, and the rest of the bundle together is the negative electrode, soldering the plug, fixed, okay.

What to do if the headphone jack of the mobile phone is not in good contact.

Try a different headset to see if it's a problem with the headphones. If there is a problem with the headphones, change them to a new one. If this is still the case.

First of all, clean the headphone jack with alcohol, be careful and gently turn it with a cotton swab. Then blow it with a hair dryer and see if it is repaired.

There is no bad contact with the headphone plug, according to what you said, there are two possibilities, one is that the headphone cable is broken, you fiddle with the cable sometimes it will be good, and it will not work as soon as you let go, in this case the earphone cable is broken, you can cut the wire skin in this part, find the broken point and fix it with tape or hot melt glue. There is also a kind of shrapnel of the earphone socket due to fatigue or poor quality of the shrapnel will not be able to rebound, resulting in poor contact, in this case the socket can generally only be replaced.

Poor headphone plugs are usually caused by oxidation of the metal surface at the connector due to age, and the surface can be wiped vigorously with an eraser, or some chemical reagents to remove oxides can be used, which can be bought in supermarkets.

Are you asking about the headphone jack or the plug of the headphones? If it is a headphone hole, you have to clean it with alcohol, use a toothpick or cotton swab to get it, it is best to use a toothpick dipped in some cotton to get it, and get it quickly. If it's headphones, just take them apart and take a look, or just throw them away.

If it's not, it's Bluetooth turned on and connected to what Bluetooth goes up, so it won't ring.

Clean the headphone jack. Over time, a lot of dust and lint can get into the headphone jack. This can be the reason why the headphones don't work because the dirt can actually block the connection between the headphones and the jack.

First of all, you have to rule out whether it is the quality of the headset itself caused by poor contact, if it is not a problem with the headset, then it is recommended that you get a professional mobile phone repair point for repair, if the phone is still within the warranty period, it will be better to send it to the manufacturer for warranty.

Wipe the plug and jack with a cotton swab dipped in alcohol (one or two drops not too much), or wipe with an eraser.

It is generally caused by dust or debris blockage, squeeze it clean with a cotton swab dipped in some alcohol, and the cotton swab should not be wet, and it can be repeated several times.

The headphone plug is in poor contact, it is likely that the ** on it stinks, you can send one, now the headphones.

Wipe the surface of the connector with alcohol, remember to dry it, and wipe the connector with a dry glasses cloth every time you use the earphones.

Super good headphones, but the recent cable has been in poor contact, resulting in one channel not being able to pronounce properly. You have to hold it with your hand to make a sound.

I don't have any tools at hand. I don't want to change it, it's so expensive to say ......I don't know if I want to find someone to fix it.

It could be broken.

I don't know how many are broken.

Change your headphones or go to the place where your phone is repaired.

Hello, dear. Why is the headphone interface in poor contact: 1. The operation of the headphone interface is not standard, which causes looseness and causes noise during transmission.

2. The earphone plug on the earphone has been in the air of Kanno sail for a long time, so that the coating on the surface is oxidized after contact with the air, and the guide hail causes poor contact with the earphone spine, which affects the use effect. 3. The earphone plug and the earphone socket are loose, and the internal welding between the earphone plug and the earphone socket is loose in the process of plugging and unplugging the earphone when using the earphone. 4. The problem of internal disconnection of the earphone cable.

At the headset plug, when the headset has poor contact. Move the plug, and there is a noise at the plug, indicating that the location of the broken wire is here.

The general situation is to come to the mobile phone headset for a long time, the source or not used for a long time, so there will be poor contact of the headphone jack, resulting in problems with the headset, the following is to introduce some solutions to solve the poor contact of the headset.

Method summary: First of all, unplug the battery, completely remove the screws that can be seen, which is the so-called removal of the B shell, and then remove the A shell, and paste it with a film to prevent dust when the screen is exposed.

The shells are now divided into two types.

1 is directly dismantling.

2 is the one with a screen (2 disassembly required).

After disassembling the A shell, the motherboard is left, find the screws and remove the motherboard, and you can see the components of the headphone jack At this time, if it is directly disassembled, it can be removed, and then replaced with a new one, if it cannot be disassembled directly, you need to solder the FPC with a welding torch (electric soldering iron). After replacement, re-soldering is completed.

Assemble the motherboard and then put it into the B shell (that is, the one in the battery compartment), and then insert the pins of the screen into the motherboard, after the assembly is completed, do not screw the screws first, and boot the test, if the boot is intact, you can screw in the screws.

After assembling, turn on the headphones to test. The headphones are as good as new!

What to do if the headphones have poor contact, it will be done in 20 seconds, it is as simple as that.

Poor contact of the jack can go to the after-sales inspection and maintenance, generally change the headphone jack, about 50 yuan, you can go to the mobile phone store to ask, different places may charge different.

Copy with a gadget.

Open the inner plug full, get the plug down, there should be four wires inside, some are three, the green is the left channel, the red is the right channel, the yellow is the ground wire, the left channel is dry at the top of the plug, the right channel is dry in the middle, the ground wire is welded at the bottom, and the approximate process is almost the same
