8 tips for repairing your computer speakers

Types of faults

If the sound of the speakers is lost on the computer, the faults can be of the following character:

• software;
• hardware.

In the first case, the sound does not work because of the sound driver of your device. Perhaps, after installing the operating system windows( no matter XP, 7, 8 or 10), you did not load additional drivers responsible for audio playback. All you need to do is go to the company's official website, which includes your sound card and download the latest updates.

Hardware problems are much more complicated and require some skills in radio and electrical engineering. In this case, you will need to use a multimeter to check the operability of all internal elements of audio devices to determine exactly why the speakers on the computer do not work.

Causes of failure

The culprits of the fact that the sound does not work on the speakers, if they are on, there may be the following factors:

1. The low cost of devices, which indicates the poor quality of the assembly.
2. Wear of loudspeakers and other circuit elements over time.
3. Non-observance of operating requirements: air humidity and indoor temperature do not comply with the regulations.
4. Damage to the conductor insulation as a result of mechanical interference( accidentally interrupted the wire).
5. Voltage fluctuations in the network.
6. Problems in the sound card of the computer
7. Software problems

To determine the exact cause of the breakdown of the speakers on the computer, you need to perform a few simple steps and by the exception method find what exactly does not work.

Basic breakdown

Among the most popular breakdowns of computer speakers are:

• Damage to the wire near the plug or from the side of the case. Occurs because of frequent bend of the conductor, as a result of which the columns on the computer do not work. Happens more often, therefore all over again it is necessary visually to examine and a little to move a hand these places. If necessary, the wire with the plug changes to a new one.
• The speaker failure. Such a malfunction is rare. To determine the operability, use a multimeter. The body of the spare part shows the nominal resistance. In the event that the value on the scoreboard exceeds the specified value, simply replace the speaker with a new one. Instructions for using the multimeter we already provided.
• Break of the primary or secondary winding of the transformer. Using a multimeter, you need to check the resistance of the transformer and, if necessary, buy a new one in the radio shop.
• The audio switch does not work( button on one of the speakers).It is necessary to check whether the food is suitable for it and, accordingly, whether it goes further along the chain.

It is recommended from the very beginning, using a multimeter, to ring the entire electrical circuit. So you quickly find the reason why the speakers on the computer do not work.

Tips for repair

So, we reviewed the main malfunctions of audio devices. Now, I would like to provide you with tips on repairing the speakers on your computer yourself:

1. If the sound suddenly disappeared, check whether everything is connected: the plug from the socket or the plug from the socket has fallen out. Frequent cases are when the reason is just such a simple break in the chain.
2. If the music is playing, the light is on, but there is no sound, check the volume control, it may be at the lowest( MIN mark).
3. To check if the problem is exactly in the speakers, connect the headphones to the system unit. If it happens that the speakers on the computer do not play, and the headphones are working, then certainly the reason in the speaker system.
4. If only one column( right or left) works, check the sound balance in the settings, it may be biased in favor of one of the elements. If you are convinced that two devices are turned on, you can also move the plug( pull it out and reinsert it into the socket), becausesometimes the cause is a weak contact. You can adjust the balance in this window if you have Windows XP installed:
5. If you decide to replace the plug, while leaving the old wire, connect the wires solely with soldering. No terminals and twists should not be.
6. If there is noise in the speakers, check the integrity of the speakers( they could tear, as in the photo below), as well as the quality of the connection of the plug to the jack. Another possible reason is a failure in the audio settings of the system.
7. In the absence of a multimeter, the dynamics of the speaker can be checked with a normal 1.5 V battery - when connecting it, a characteristic rustle and a diaphragm shift should occur.
8. Another option is to connect the audio system to a computer, not to a DVD player or phone, for example. If the sound appears, then it's the PC sound card.

That's all I wanted to tell you about why the speakers on the computer do not work and how to repair them yourself. We hope that now you can independently find the cause of the failure and eliminate it without any special difficulties!
