No sound in car radio

No sound in the car radio? There can be many reasons. Therefore, before starting repair work, you must find the problems that led to the breakdown. Without the necessary skills, you can consult with a specialist who will tell you exactly how to act. In particular, if there is no sound in the car radio, most often the problem is associated with a malfunction of the power circuits.

Why does the car radio sound disappear?

A modern car is not only a standard means of transportation, it has long been a whole range of useful options.
What does almost every motorist use when he goes on the road? This includes heated seats, heated windshield and rear-view mirrors, and air conditioning. But the most commonly used equipment is the standard multimedia system. To avoid getting bored on the road, you can turn on the radio or your favorite music in the background. Some drivers are accustomed to playing movies while on the road, but this can distract from driving. As a rule, a standard car radio has 2 speakers. Over time, equipment breaks down

Radio tape recorders began to appear in cars several decades ago. Nowadays, many car owners cannot imagine life without it, because music while driving allows them to relax or, conversely, cheer up. But, as with any other equipment in a vehicle, breakdowns can occur. For example, one morning a car owner sits in his favorite chair, turns on the radio, but it doesn’t work. But the most common problem is when the complex works, but there is no sound. Most likely this occurs due to problems in the power circuit. Let's consider the main reasons for the disappearance of sound in the radio.

The first reason that immediately appears in your head as soon as the sound disappears is a malfunction of the speakers. As a rule, a standard car radio has 2 speakers. Over time, equipment breaks down. The resource is reduced much faster if the motorist does not provide timely maintenance and does not monitor the condition of the wiring. Only one speaker can fail, or all of them can fail at once. If the entire system does not work, you need to carry out a full diagnosis, since the reason may lie in another radio unit.

If the car is used for a long time, you need to periodically check the condition of the wiring.

Another obvious reason is a malfunction of the amplifier. If this device fails, there will be no sound in the cabin. The third reason is bad contacts. The wires on the device could simply have become loose. If the car is used for a long time, you need to periodically check the condition of the wiring. In most cases, to solve the problem you just need to solder the wires. If all of the above reasons do not apply, then you should check the electrical circuit for a short circuit. If the system has such a problem, the device will not have enough power, which will affect its performance.

If the car's sound system is too powerful, this can also lead to loss of sound from the speakers.

The last reason applies to tuning enthusiasts. Many motorists are not satisfied with the sound quality of the standard radio, so they are starting to think about installing third-party equipment. And no one prohibits such alterations if they are carried out in accordance with the law. However, in some cases, owners simply do not calculate the power of the system and install the first one available. If the car uses too powerful speakers, this can also lead to loss of sound from the speakers. In high load mode, the amplifier may not be able to cope with the work, and this can lead to its breakdown. To avoid problems during operation of the radio, you should periodically monitor its condition and carry out appropriate maintenance. If problems have already appeared, it is better to contact a specialist, as the cause may lie in a circuit malfunction.

Bottom line. A radio is a must-have piece of equipment in almost every car. Sometimes this device fails, causing the sound to stop coming from the speakers. The problem may lie for various reasons.

Main causes of malfunctions

No sound on the car radio

The sound on the radio may disappear if:

• The speakers (see How to choose speakers for your car radio yourself) are not working properly. If one of the speakers works, there will be sound, but it will be of poor quality. It is extremely rare for all speakers to fail at the same time. If, after all, the cause is faulty speakers, then you need to diagnose the entire speaker system, since another problem could lead to their failure (for example, one of the wires is poorly insulated, so a short circuit has occurred);
• It is quite possible that the sound disappeared due to a malfunction of the power circuits or the radio amplifier;
• It is not necessary to exclude the possibility that the contacts on the radio tape recorder have become loose. If one of the contacts is broken, then it must be soldered;
• There is also a possibility that a short circuit occurs in the circuit, so an insufficient amount of energy is supplied to the radio;
• The sound may also be lost due to the fact that the user uses too weak or powerful speaker systems for the radio. As a result, too much load is applied to the amplifier, which causes it to break down.

No sound in the car radio

Note: Repairing an amplifier is only possible if it is not completely burned out (and even then, this can only be done by specialists). Otherwise, it will need to be completely replaced.

The radio works, but there is no sound: what could be the reason

Check the speakers
For many drivers, the radio in the car is an integral part of it. Because it allows you to enjoy pleasant music or just your favorite song during a trip. With such support, even the longest journey will not seem boring.

As soon as problems arise with the operation of the car radio, it causes a lot of inconvenience. The driver tries to eliminate it and return the device to its previous functionality. One of the most common breakdowns is lack of sound. There are many reasons for this. It is very important to install it correctly. This is the only way to count on high-quality operation of the device after repairing the breakdown. Sometimes you can do this yourself, but it is better to consult with professionals. They will help you solve this problem and tell you what is best to do in the current situation.

The radio is working, but there is no sound - reasons

At first glance, nothing has changed in the operation of the radio. It works as before, but there is no sound. This is often due to a breakdown in the power circuits. But there are other situations that cause the sound to disappear. These include:

The radio works, but there is no sound, what should I do?

The sound in the Pioneer or Supra radio works according to the same principle, as shown in the photo. Therefore, the problem resolution scheme is carried out according to one type. The main thing is to correctly determine the cause of the breakdown before you begin to carry out your plans. Otherwise, you can only aggravate the situation and then the repair will not help, you will need to purchase a new car radio.

Even if the sound in the car has disappeared, but the radio is working, then do not despair. If the problem lies in the amplifier, then you need to take a soldering iron, tweezers and a new part. Then perform a series of sequential activities. They are:

1. Disconnecting the radio;
2. Removing the top and bottom covers of the device, and then the front panel;
3. Preparing the soldering iron for work. To do this, it is heated. They must be handled with extreme caution. Because if you touch any other element, it can melt under the influence of high temperature;
4. Warming up the powder. This procedure is performed for 20 minutes with periodic repetitions;
5. Removing the fee. Before doing this, they need to use pliers to make the clamps straight;
6. Soldering the microcircuit. The parts that are next to it are covered with foil. This event allows you to protect them from damage;
7. Preparing the site for installing a new part. To do this, the remaining solders are removed from the board;
8. Installation of a new plateau. Often his legs are not bent as they should be. Then, using tweezers, they are straightened;
9. Fixing the microcircuit;
10. Soldering the legs of the part;
11. Checking the correct installation of the new element;
12. Device assemblies.

Then it is installed in its original place. Check the quality of work. During repairs, it is necessary to ensure that they are done correctly. Since a new disassembly can lead to the following disruptions in its operation.

In the video you can see this process. It is performed by a professional who has the necessary knowledge, skills and experience. The specialists clearly demonstrated the techniques that need to be applied and how best to do it in order to achieve a high-quality result.

Of course, understanding why the radio works but there is no sound is not easy for many people. Since, at first glance, this is one whole device. Therefore, if one element fails, the entire radio should stop working. But the Supra and Pioneer manufacturers foresaw this and made it in such a way that the parts do not depend on one another.

This simplifies car radio repairs.

So it’s enough to replace one of them, which will take less time and be cheaper. After this, the device will work again as before: the sound is high-quality and loud.

Replacing the radio amplifier

No sound on the car radio

By the way, replacing an amplifier may be necessary not only when it is broken. In some cases, it is changed because drivers are not satisfied with the sound produced by the radio. It’s just that a standard amplifier allows you to listen to music with only a small sound, and when you increase it, the sound will be distorted. To replace the amplifier you may need:

• Soldering iron;
• New amplifier;
• Tweezers.

The process occurs in several stages:

• Disconnect the radio;
• Remove the top and bottom covers, as well as the front panel;
• Take a powerful soldering iron and heat up the solder. Under no circumstances should it touch other parts, as this may cause them to melt a little. It is necessary to repeat several times. In general, the procedure takes about 15 minutes;
• Using pliers, straighten the clamps and remove the board;

Note: if the solder has not been removed everywhere, then this place should be heated with a soldering iron and the board should be lifted, avoiding distortions.

• Unsolder the microcircuit. It is imperative to protect all nearby latches with foil;
• Prepare a seat for the new microcircuit. For this purpose, it is necessary to remove all solder residues from the board holes;
• If the legs of the new board are not bent as they should be, then they can be straightened with tweezers, and then the bends can be adjusted with a ruler;

Note: It is easier to straighten the long legs first and then the short ones.

• Install the microcircuit in the seat and solder its legs;
• Carefully check whether everything was done correctly;
• Assemble the radio and install it.

Camry radio not working

If there is no malfunction of the device, then the reason for the radio not turning on is related precisely to the electrical circuit. From experience, there can be two types of malfunction:

• blown fuse for the head unit;
• blown 100 amp fuse in the main fuse box;
• problems in the power supply system that require inspection by a qualified auto electrician.

If the screen is on, then the problem is not with the power supply. The problem of a blown fuse often appears in those cars in which the car radio and the car cigarette lighter are located on the same section of the network. This is also typical for Toyota models of previous generations. At the time of release of the vehicles, additional functionality of the devices was not expected. Accordingly, the network capabilities are not designed for the current load.

Please note that when the screen is turned off, you need to consider the issue of a non-working standard car radio for other reasons. Try applying 12 V to the device as a test.

The problem is often the car cigarette lighter. Note that in more powerful cars, it is separated into a separate circuit. Its operation is controlled by a separate fuse. This, for example, is typical for the Land Cruiser. Usually the cigarette lighter and Toyota Corolla radio do not work at the same time. As was said, the problem is in the design of the on-board network of cars of the previous generation and the increase in the power of on-board electronics, which are not designed for an electrical circuit.

Problems with the car radio may arise after the network is shorted to ground (body). Typically, such a network malfunction causes a number of fuses to melt. The cigarette lighter in cars before 2008 is often used as a voltage source for external devices. When the car radio is turned on, the fuse will most likely fail.

CAN buses for Corolla 120, Camry and others

If you decide to seriously upgrade your Toyota Corolla, Avensis or Camry, which includes connecting a number of on-board devices, we recommend connecting all on-board devices to the CAN bus. In this case, as a protection, outputting the charge to the body (ground) is only a backup method of protecting the network. This is a specialized data transmission system with a hardware solution that allows you to conceptually solve the problem of network congestion.

The bus design almost completely eliminates overloads, which completely eliminates malfunctions. With such an architecture, it is almost impossible to encounter a Toyota Camry radio that does not work. When you turn it on, you will always be pleased with the calmly burning screen of your updated Toyota Carolla 120 or previous generation Camry.

Doesn't turn on

One of the reasons why the tape recorder in the car does not work, although there is power, is a blown fuse. This can happen due to overload caused by listening to music at high volume for a long time or a short circuit in the speaker wiring. As a result of this malfunction, the radio refuses to turn on.

To fix the problem, remove the device and remove the fuse. Its rated current is 5 or 7.5 A. Since it is impossible to accurately determine by appearance whether the fuse is intact, the serviceability of this part is checked using a tester or multimeter.

If the car radio was connected through a car mounting block, then the integrity of the fuses in it should also be checked.

The next reason why the radio does not turn on is a break or chafing of the power wires. The contact in the standard block could also come loose due to contamination or loose connectors. To fix this problem, you should carefully inspect the wiring and connectors. Particular attention is paid to the connection of the receiver to ground or the car body. Broken wires should be replaced and connected as securely as possible.

The terminals on the connector must be thoroughly cleaned of dirt and securely crimped with pliers.

Incorrect connection also leads to the fact that the radio in the car does not turn on. To resolve this problem, you should carefully inspect the wiring. You can identify the wires coming from the battery using a test lamp. Wiring to speakers is often done with two-core cables.

To make the correct connection, the positive pole of the battery power is connected to the red and yellow wires of the car radio, and the negative pole to the black wire. The blue wire must be connected to an active antenna or amplifier. If the positive wire from the battery is connected to the red wire, and the yellow wire is connected to the ignition switch, then the audio device will not turn on until the key is turned.

If all connections are made correctly, the player will turn on when you press the button.

Another common reason why the radio stops working is an internal malfunction of the audio device. The amplifier and controller microcircuits burn out due to voltage surges in the on-board network caused by a generator malfunction. Sometimes the radio display lights up but there is no sound. In this case, the receiver must be replaced or repaired. The operation of the generator is checked at a car service center.

What if the sound disappears when connected to the car charger?

I bought a Chinese video recorder with a navigator and radar detector. Downloaded Yandex navigator and Yandex maps. There is no sound accompaniment. How to setup?

Have you looked at your navigator settings?

Thanks for the tip

Certainly. Only there the Chinese write how to regulate the sound, but how to make it not speak.

Thank you, thorough and intelligible.

What phone do you have, what version of Android? How long ago did you update your smartphone and navigator? Are there any sound problems on the phone itself?

Everything worked out . THANK YOU .

Hello, look at the sound settings in the on-board navigator, maybe you need to enable or disable something there

I DID EVERYTHING ACCORDING TO THE INSTRUCTIONS STEP BY STEP. The problem remains, there is still no sound on the Samsung-Galaxy-S7-Edge smartphone. Maybe the onboard navigator is interfering? Could it be a bluetooth problem? The on-board navigator works clearly with sound, but the maps on it are outdated, so there is a need to use the Yandex navigator of the smartphone. Can't anyone help? Eugene

Same problem. Have you solved it yet? If you decide, please share.

I do everything according to the instructions, there is no sound. Was there yesterday morning, then disappeared.

Try restarting your smartphone, turning it off and on completely. Before the sound disappeared, did you do something on your phone, maybe you changed some settings or installed an application?

Make the music quieter, there are no other options if the sound in the navigator is at maximum. Navigator on a smartphone?

The navigator is installed in the head unit of the car. When driving, due to the noise of the car, it is difficult to hear the support of the Yandex navigator. The sound in the navigator is set to maximum. Hyundai Solaris car.

Is Yandex navigator installed in the car's head unit? Have you checked the sound settings on the device itself?

What to do if the sound disappears on the Samsung a50, a51, a10, a31, a01, a11, a40, a71, a20s

Why the sound disappeared on your Samsung a50, a51, a10, a31, a01, a11, a40, a71, a20s, of course, you won’t get a definite answer, but I’ll tell you what to do.

We will proceed from the fact that the sound does not work on the Samsung Android for various reasons and there are many factors.

As you can see, different errors occur in Samsung smartphones and tablets, so there is no universal recipe, but in any case it can be a huge irritation.

First of all, check the settings, since these phones have 4 of them at once, and not, as you might think, only one.

To do this, click on the button, and then, when a vertical gray wide slider appears, three horizontal dots at the top and move the sliders up.

Keep doing this a few times as sometimes the phone will trick itself into thinking it is in headphone mode.

Also, by doing this step, you will likely remove any accumulated dust or dirt that may also be causing this problem.

Next, see if there is a software update. It's rare, but sometimes it works. There will be a fresh update, download them. You may also experience audio problems due to moisture getting into the phone or around the speaker.

You can remove this moisture by turning off your phone and placing it in a container with rice for 24 hours. Problems may also appear after connecting the device to a Bluetooth device.

Similar to the previous step, another process also turns Wi-Fi on and off. This restarts any connection between the smartphone and any speakers or Wi-Fi related devices.

It is also possible that there is a problem with the equipment that needs to be repaired or replaced. Many people stated that deleting unrelated apps fixed the problem. This, of course, can be a pain, so in this case, try deleting one app at a time and then see if the sound comes back on.

If the fixes above worked for you, or if you tried something different, please share. Also a great place to look for solutions is the comments section below, where there may be more tips on how users have fixed their Samsung phones. Good luck.
