The radio does not start. What to do if the Chevrolet Cruze radio does not work. Typical car radio malfunctions include

A car radio, like any other device or mechanism in a car, can fail. As practice shows, car radio repairs are usually carried out in the event of improper operation of the device or when malfunctions occur that are not related to use. In this article, we propose to familiarize yourself with the main causes and methods of eliminating audio system breakdowns.

Standard car radio

It's no secret that over time, the mechanical elements of a multimedia system tend to wear out. So, if the system does not turn on or turns off, it is necessary to either repair or replace it.

But first, let's look at the main reasons why the radio does not work:

The device is dirty. If the radio stops working, this may be due to contamination of the mechanisms - dirt or dust may accumulate between them, especially if the system is used in harsh conditions. As a rule, in this case, optical or mechanical components break. One of the signs of contamination is the disc sticking and the inability to play it normally.
Mechanical faults may also be the cause. This type of failure is usually associated with the power circuit. If the connection of the head unit was made incorrectly from the beginning, or the electrical circuit is characterized by sudden changes, then there is nothing to be surprised at. The first symptom of problems with the power circuit is the absence of the screen backlight or the inability to start the radio.

Malfunctions and ways to eliminate them

Before you remove the radio from the car and begin repairing it, read the list of faults typical for audio systems. Removing and repairing a car radio from a car is not such a problem, but before you take it out, you need to know exactly what to repair.

There is no display backlight or the system does not turn on

Perhaps the problem is the lack of power at +5. If you decide to get the device out and repair it yourself, first of all you need to pay attention to diagnosing the second contact of the CN701 connector. It should have a positive voltage of 14 volts, this voltage should be transmitted to the collectors of the transistors. If there is no voltage, repairing car radios involves replacing transistors or a zener diode.
There is no power activation signal. Before repairing car radios, you need to check the voltage of + 4.8 volts on the fortieth pin of the IZ901 controller. You should also check for the presence of a pulse on the third contact of the controller.

Testing the multimedia system with a multimeter

The car radio turns on, but there is no sound or noise

Car radios need to be repaired independently or by a specialist if there is no sound volume or if the volume is increased and tracks are played, the sound becomes loud.

There may be several options:

There is no sound when starting the engine. If the sound disappears even when you increase the volume or there is no sound, this is usually due to the absence of the Stand.By signal. In this case, when the sound has disappeared and there is no sound, you should check the pulse high level at +4.8 volts. We are talking about the fourth pin of the IC901 controller. If the sound disappears and there is no pulse, then car radio repair involves replacing the controller. If the sound disappears when you start the engine and increase the volume, you need to diagnose the four contacts of the power amplifiers.
When starting the engine the sound is loud. If the sound is loud when the volume is increased, check for voltage at the bases; the resulting parameter should not be equal to zero. It often happens that the sound becomes loud when the volume is increased due to zero voltage - if this is the case, then car radio repair will be based on replacing transistors. Also, the sound sometimes fades when the volume is increased due to the Mute button not working - there is a possibility that the problem lies in the controller. If there are problems with sound volume, you need to diagnose transistor Q802.
Volume problems may be caused by one or more circuits in the amplifier not working properly. If there is no sound, you need to diagnose the entire “path” from the input to the output of each circuit. Repair of radio tape recorders comes down to replacing transition capacitors or circuits.

Does not read disks, flash drive or disk is stuck

Why doesn't the radio read a flash drive or disk after starting the engine? The disk is stuck, stutters, the system does not see the flash drive?

The reasons may be the following:

The radio does not read the flash drive, does not see the disk, or the disk stutters or gets stuck after starting the engine. Perhaps the device simply does not understand the recording format. Radio repair in in this case not required, you just need to burn the disc in a different format.
If the system does not see the disk when the engine starts, the disk is stuck, stutters or heats up, this may be due to contamination of the optical lens. As mentioned above, problems in the operation of the buttons and the device as a whole after starting the engine can be associated precisely with dirt. In this case, the problem is solved by using a special cleaning disc. The operation of such a disk is carried out in accordance with the requirements specified in the instructions. Can be produced self-cleaning system by blowing elements or cleaning with cotton wool.
Another reason may be the lack of laser current; you can get rid of such a malfunction by adjusting it.
Inoperability of loops and wires. It is possible that during the operation of the car, the screws inside the structure simply became loose, or it could be a leakage of resistors.

Buttons don't work

The buttons don't work - there are several reasons. Firstly, there may be mechanical damage to the buttons. To restore the functionality of the buttons, you need to disassemble the front panel and check the condition of the contacts. Perhaps the contacts from the buttons are simply coming off and need to be re-soldered. If the button is inoperative, it will have to be replaced.

Secondly, the problem with the buttons may be due to a malfunction software. The problem can be resolved by rebooting the audio system and returning its functionality to the factory configuration. All settings will be erased from memory. After returning to factory settings, the device must be turned off for a few minutes.

The device is heating up

If the radio gets hot and turns off randomly, there may be several reasons:

The system heats up and turns off as a result of poor power supply. Lack of power will lead to the radio turning off randomly, or this is due to power failures. When the radio gets warm and turns off, you need to check the power cable - perhaps it just comes off or is broken, then it will have to be replaced.
The device heats up due to poor ventilation and turns off when it overheats. If the system gets hot, this indicates insufficient ventilation. This malfunction is relevant for Pioneer radios and, as car owners of such systems assure, there is nothing to worry about. But if the system constantly heats up and then turns off, you need to consider additional ventilation.
Sometimes the device turns off due to software glitches. You can try to solve this problem by resetting the radio to factory settings.

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

(2 ratings, average: 1.00 out of 5) Loading... Check columns

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 frequent breakdowns is the absence 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 speakers are faulty. There are two of them in the radio and they can simply break. Then the sound will not be played. As practice shows, there are mainly cases when one speaker breaks. This also affects the sound quality, it becomes quieter. If both do not work, then it is necessary to carry out a full diagnosis of the device. Since the cause of the breakdown could have been a completely different problem;
The amplifier is faulty;
The contacts on the device have become weaker. This happens over time. One or more contacts are broken. To correct the situation, it is enough to simply solder them;
Closing the circuit. This leads to the fact that the equipment receives a small amount of electrical energy and it is not enough for its full operation;
Use of a powerful speaker system. When choosing it, you need to calculate the capabilities of the radio. Is she able to withstand them? Otherwise, the load on the amplifier will be very large, which will lead to its breakdown. It is very rarely repaired, mostly replaced with a new one. This procedure is also carried out when the owner is not satisfied with the sound. Since its standard version is designed for low volumes, when it is increased, the sound is greatly distorted.

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 solution to the problem is carried out according to the same 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:

Disconnecting the radio;
Removing the top and bottom covers of the device, and then front panel;
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;
Warming up the powder. This procedure is performed for 20 minutes with periodic repetitions;
Removing the fee. Before doing this, they need to use pliers to make the clamps straight;
Soldering the microcircuit. The parts that are next to it are covered with foil. This event allows you to protect them from damage;
Preparing the site for installing a new part. To do this, the remaining solders are removed from the board;
Installation of a new plateau. Often his legs are not bent as they should be. Then, using tweezers, they are straightened;
Fixing the microcircuit;
Soldering the legs of the part;
Checking the correct installation of the new element;
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.

You can see in the video 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.

How to determine why the radio turns off and fix the problem

(No ratings yet) Loading...

When listening to the radio in a car, especially with a fairly powerful audio system with good subwoofers and tweets, many devices experience malfunctions. Most often, car enthusiasts ask the question, why does the radio turn off when the volume is increased? Indeed, turning off the device when the volume is increased, especially when transmitting power to the bass, in a car audio system often turns off the radio.

What is the problem?

In this case, the device turns on again on its own without any problems, but operates at a lower volume. When I try to increase the volume, the situation repeats. Often, after turning off the radio, the user has to turn it on himself, which is very inconvenient.

Another situation that forces drivers to ask why the car radio turns off without warning is when the engine starts. Depending on the model and brand of the radio and the car, the shutdown can be short-term (when you start the engine, the device turns off for a couple of seconds and then plays again), or permanent, when you have to turn on the radio and adjust the sound again.

In more complex cases, after turning off the radio, the equalizer settings and other operating parameters of the device are reset, after which you have to re-configure the radio's operating parameters after turning it on. This causes a lot of inconvenience for drivers, and in order to find out why the radio turns on and off, you often have to remove the device from the socket and look for the root of the problem in the connection.

Let's look at the most common reasons for the radio turning off spontaneously and ways to solve the problem. They may consist of malfunctions of the audio system itself, as well as problems with the redistribution of voltage between all audio system devices in the car.

A defect in the radio itself or an acquired malfunction

Factory defects in car radios are not such a rare occurrence. During the production of the radio, various defects could have occurred inside the device's microcircuits, which lead to short circuits and other operational problems. To understand why the radio turns off when you turn up the volume, you will have to take it out of the car and take it to a car service center or service center so that specialists can diagnose the audio system.

Malfunctions when connecting speakers to the radio

Incorrect connection of speaker wires to the radio connectors can also cause spontaneous shutdowns of the device. Especially when you start a car engine with a short-term increase in power, a short circuit occurs in the wires with an incomplete connection (input to the plug). To eliminate this malfunction, you need to visually check the contact level and, if necessary, insert the speaker plugs into the radio connectors more tightly.

You can also check the integrity of the wires leading to the speakers: turn on the radio at normal volume and disconnect the speakers one by one, increasing the volume. If the radio does not turn off when you increase the volume, then you can understand that the malfunction lies there. Replacing the speaker wire or contacting technical service helps.

Surge protection in the radio itself

This is the most common reason why the radio turns off when the volume is turned up. Many drivers, when contacting a car service center, hear from specialists that the radio is equipped with overvoltage protection, which is triggered when the power increases. Adding sound to the radio leads to an increase in power consumption from the battery, which can lead to automatic shutdown sound. It is impossible to bypass this protection, because... otherwise, the radio may burn out completely. To solve the problem of surge protection, experts recommend installing an amplifier between the radio and speakers (see video on how to do this here).

Another way to solve the problem of the radio automatically turning off when the volume increases is to check the wires leading from the radio to the speakers, which may have a short circuit. Check all the wires leading to the speakers one by one - if there are any that are pinched or twisted, then by changing their position to the correct one, the problem with the operation of the radio may disappear. If the wires are severely damaged, it would be advisable to replace them with new ones.

Anyone who spends a lot of time behind the wheel knows that a car radio is very important detail in car. Any trip is more enjoyable accompanied by your favorite music. Currently, there are many models of car radios to suit every taste and budget. They are equipped various functions and are able to satisfy any motorist.

Regardless of its cost, a car radio, like any other complex electronic device, can sometimes fail. It often happens that the car radio simply stops turning on, or turns on and immediately turns off. There may be several reasons for this malfunction.

Why doesn't my car radio turn on?

Main causes of malfunction:

Why does the radio turn on and off:

Why does the radio turn on by itself?

At self-installation any electrical equipment, including a radio, in a car, you need to be very careful. Before installation, you must carefully study the instructions. Be sure to follow safety precautions while working. If installed incorrectly, not only may the radio malfunction, but also more serious problems associated with the vehicle's electrical system.

Like any other device or mechanism in a car, it can fail. As practice shows, car radio repairs are usually carried out in the event of improper operation of the device or when malfunctions occur that are not related to use. In this article, we propose to familiarize yourself with the main causes and methods of eliminating audio system breakdowns.

A rather unpleasant breakdown during vehicle operation can be the failure of sound-reproducing equipment. Sometimes this problem can be solved on our own, but if possible, it is better to contact a specialized auto repair shop. Because, as with a seemingly harmless breakdown at first glance, there may be serious reasons that can subsequently lead to a very serious breakdown.

Common malfunctions in car players:

buttons stick;
The standard radio stopped working;
The backlight does not turn on;
the player refuses to read discs and flash cards;
The cigarette lighter and radio stopped working;
the cable and the infrared head fail;
The radio stops working after a car wash.

Cigarette lighter and its connection with the car radio

Cars from the LADA family (2110, 2113, 2114, etc.) have virtually no different feeding patterns from each other

power supply to the player. Despite the fact that this power supply is connected to a common electrical fuse with the heating system (stove), the rear defroster and the car cigarette lighter.

If all of the above-mentioned equipment is working properly, but the car radio is not, then the fault should be looked for in the sound-reproducing device itself. As a rule, they are equipped with their own fuse, which is located on a section of wire located between the player body and the plug. Or in a block of wires that is inserted into the body of the radio.

To make it easier to identify such faults, it is good to have a screwdriver in your car’s repair kit - a probe with an LED or a sound signal.

If you find a faulty safety element, replace it with a new one.

Car radio screen (display)

Also, the backlight of the screen (display) often goes out on radio tape recorders. Pioneer equipment especially suffers from this. So if your Pioneer brand car radio has stopped working, to bring it back to proper (working) condition:

Buttons

What to do if the buttons in the VAZ 2114 (VAZ 2110) radio stop working?

The main reason that the buttons stop working or stick is, as a rule, dust and dirt getting under them or accidentally spilling soft drinks on the panel. As a result, the radio components overheat and the buttons fail to respond to commands when pressed. This can also happen for purely mechanical reasons.

That is, due to a broken solder contact. If a malfunction occurs such as sticking buttons of a car player, it is recommended to disassemble the top panel and clean the board and the connection points of the buttons with it, and also check the contacts of all buttons with a multimeter.

CD, DVD, MP 3.4

The car's standard player does not reproduce work from these media. Most possible reasons refusal to work may be:

faulty drive mechanism;
burnt out electric motor;
contamination on the reading head of the optical lens.

The best way out in these situations is to contact a professional technician to correct them. However, you can clean the laser lens yourself by purchasing a special cleaning disc.

Radio receiver

The receiver picks up radio broadcasts.

This mainly happens due to loss of contact between the radio receiver and outer part antennas. Finding the breaking point is quite a troublesome and tedious task without the proper equipment, so it’s easier to turn to an auto center for help. Moreover, eliminating such a breakdown is not expensive at all and will also save your nerves and time.

There are many reasons why the radio tape recorder stopped working. Both common to all models of audio equipment, and individual in nature inherent in any particular manufacturer (brand).

A car radio is a complex device that can experience malfunctions. Various reasons lead to the radio not turning on.

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 according to appearance

It is impossible to accurately determine 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 terminal of the battery power is connected to the red and car radio, and negative - to black. 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.

Turns off during operation

It happens that the radio turns off during operation. This problem may be caused by a poor or unreliable connection in the power circuit, which occasionally becomes loose when driving fast on rough roads, resulting in an unexpected shutdown. To fix the problem, you need to connect the power wires of the car radio more securely. Connecting the negative wire of the car radio to the car body is carried out as follows:

Find the stud closest to the radio
Clean it from dirt and paint.
Take a piece of wire with a terminal that has a hole of a suitable diameter.
Connect one end to the negative terminal of the radio
Place the terminal onto the stud and screw it securely.

Unreliable mounting of the car radio on the dashboard also leads to malfunctions, including shutdown. Another reason for sudden shutdown is the protective timer built into the radio. It is used to avoid draining the car's battery if the device is accidentally left on without pressing any buttons for a specified period of time. To deal with this problem, you just need to turn on the radio again.

Buttons don't work

This malfunction is caused by poor contact or careless installation of the front removable panel of the head unit. The buttons do not work due to natural wear and tear caused by active use of the device. This problem will appear the sooner the harder you press the buttons. If the volume control encoder is worn out, control will not occur correctly. When turning the knob clockwise, the volume decreases instead of increasing, increases randomly, or does not increase at all.

To eliminate this problem, you should carefully remove the front panel and wipe the contacts on it and the radio itself, and then put it back in place. When installing, make sure that the panel fits tightly and evenly into place, and that the latch clicks into place. To replace worn or sunken buttons, you can take the panel to an electronics workshop. Regardless of the condition of the head unit, do not use excessive force when pressing the buttons, touch sensor, or turning the volume control to prolong the life of the controls.

The sensor or display does not work

An internal fault in the car radio results in the display not working. The cable connecting the display to the head unit may have come loose. This problem can only be fixed at a service center. You should not repair the display yourself to avoid causing more damage.

For the same reason, the sensor on the radio does not work. If this device is equipped with a control panel, then using the latter you can turn it on, off and perform other operations. Inaccurate installation of the front panel with a display or sensor also leads to incorrect operation of these components of the car radio.
