How to fix the column?

columns Computer speakers can always fail, especially if the user preferred an unknown manufacturer. Many simply buy new equipment to replace the old one, but this is not the best way out of the situation. There are dozens of different techniques to restore the working capacity of the speakers. How to fix the column in your case? Most likely, you will find the answer below.

Speaker unit

The main purpose of sound output devices is to amplify the weak signal that the equipment receives from the PC's audio card. The speakers are a stereo audio amplifier. You can classify the entire filling in three blocks:

• Power supply.
• Stereo power amplifier of audio frequencies.
• Multiple speakers.

Important! Power such devices are obtained from the network of 220 volts. But there are cases when the technology is powered by a USB port with a voltage of 5 volts. And with a computer devices connect, as a rule, with the help of all known jacks in 3.5 millimeters.

Kinds of removable breakages

To repair the column, you first need to do the diagnostics:

1. Plug the devices into a network or USB port. If the diode is on, the UMZCH( audio amplifier) ​​is working and quite working.
2. Touch the tip of your finger with 3.5 mm output. Correct columns will publish a background of 50 Hertz. This buzz you do not confuse with anything.

Important! If there is no noise, the problem may be: a 3.5 mm plug or UMZCH.The latter, as a rule, breaks very rarely, so first of all, take the plug.

How to fix a column for music? Different cases require different actions. Let's talk about some of them.

Only one

is defective. Often it happens that only one column is out of order.

Important! The breakdown can be caused by a broken connection in the plug and the audio card slot of the computer.

In order to get rid of the problem, it is necessary to do the following:

1. Disconnect all devices from the mains. Precautions in the first place.
2. Take a cotton pad or piece of cloth, moisten with industrial alcohol and carefully wipe the plug.
3. If the problem is not solved, then you have to replace the plug itself.

It happens that the performance of the speakers in the speakers is broken. You need to be able to determine this.

Testing the speakers

Repairing the speakers for the computer with your own hands is not the trickiest thing, but you need to know what we're facing. Let's talk about the most rare failure in the columns for computers - this is the failure of the speakers themselves.

Important! According to statistics, most often the cable is erased or the contact in the plug is broken, which breaks the speaker.

If you suspect that the problem is in the speakers, then to check its performance is very easy. To do this, follow the following instructions:

• Get a digital multimeter or an analog tester.
• Set the measurement limit to 200 ohms on the meter.
• When the probe and the speaker come in contact, a value that does not exceed 16 ohms should be displayed.

Important! You can look at the speaker itself, it should indicate the value of its resistance: 4, 8 or 16 ohms.

• If the values ​​differ from the nominal values, the speaker is broken. But do not get upset, because its cost in the radio market does not even exceed $ 2.

Important! If neither a multimeter, nor any other tester you have and is not expected, connect the battery in a half Volt. A good speaker will please you with signs of life when you touch the battery.

Change the wires and plug

The plug from the speakers broke, how to fix it? Here, too, there is nothing complicated. Just need to know how to make a replacement.

Important! Purchase a plug and wires for stereo speakers only. In other words, the sound must necessarily be divided into two channels.

The plug is also made using stereo technology. The seller will be able to tell you where and how many outputs are available in each plug from the assortment. But the wire must be three or four-core.

Important! The easiest way to install new components is to solder it, and it's the only one in fact. No twists will help to achieve a good effect.

Eliminate rustling in

columns The most budgetary models of audio systems are equipped with adjustable potentiometers. These are the most common resistors in which there is resistance adjustment. Using a special slider, the physical magnitude of the electrical resistance changes. New and high-quality speakers provide silence during such actions, but in them, over time, the grease dries, which leads to the appearance of foreign sounds and sparks transmitted through UMZCH.

In order to solve this problem, it is necessary to acquire a special tool and lubricate the "path" in the potentiometer. If you do not want to poke around inside, you can take the technician into the service and replace the annoying part for a small amount.

But if you have read this far, then most likely, you will eliminate all the problems yourself. Repairing the speakers for the computer with your own hands will help not only save money, but will also provide a unique useful experience for future equipment repair.

Lubricate the volume control

First, you need to disassemble the column in which the potentiometer is mounted. Using a soldering iron, it must be dished and disassembled. Difficulties at work depend not only on you. The manufacturer is very often hacked in production.

After all the shuffles, you need to do the following:

1. Remove the old tool from the potentiometer track.
2. We clean the entire surface area from dirt and dust accumulations. It is best to use the most common school gum.
3. We take technical petroleum jelly and put it on the path.
4. It only remains to assemble the volume control and solder it back.

If you did everything right, then the performance of the speaker system will become stable and of high quality, and the speakers themselves will only play music, excluding all rustles and noises.
