There is no sound problem with the car stereo 150

First of all, it's not a big problem, it should just be a line connection problem.

Extended information: The car suddenly has no sound, first check whether the power supply of the CD player is normal, as long as there is electricity, the indicator light should be on, and the CD cabin can also be switched on and off normally. If there is no electricity, please check the power supply, i.e. the fuse box and the wiring.

Car audio is an important way for drivers to fight fatigue during the journey, and it plays a vital role in safe driving and car driving safety, so you must not slack off and be careless.

Whether you have modified the audio for the car, if so, you need to check the modified fuse, or check whether the audio output cable has fallen off.

If it still doesn't work, you need to consider whether there is a problem with the horn. However, auto audio is often a radio and playback device designed to reduce the boredom of the driver and occupants of travel. It has reached a high standard in terms of timbre, operation and vibration resistance, and can cope with the bumps of the car on the rugged road, ensuring the stability of performance and the perfect sound quality.

Therefore, this impression is unlikely.

The audio suddenly has no sound, without affecting the driving of the car, you can go to the nearest professional repair shop or 4S shop to check it.

Ignore it, the electronic original is sometimes unclear, maybe turn off the stereo, turn off the ignition, and then turn it on, and there will be a sound. The sound problem is sometimes so capricious.

The car stereo suddenly does not make a sound, which may be the following problem:

1. Check whether the power supply of the CD player is normal, the indicator light should be on when there is a power supply, and the CD navel should be able to switch on and off normally.

2. If there is no electricity, check the power supply, that is, the fuse box and the line.

3. If there is electricity, consider whether it is a modified audio, if so, check the modified fuse, if not, check whether the audio output line is off.

4. Consider whether there is a problem with the horn.

I just installed a set of RV6A last year, the sound quality is very good, the sound field is open, and the vocals are natural and delicate. I installed it in Heyuan, whether it can be installed in Shenzhen, you can call ** to the headquarters to consult.

The car suddenly went silent. First of all, check whether the power supply of the optical drive is normal. As long as the electric indicator light is on, the disc room can be switched on and off normally. If there is no electricity, check the power supply, i.e. the fuse box and the circuit.

Hello, it takes time to type, please be patient and wait for a while, and give you a reply right away [smile] Hello, I'm happy to answer for you. There is no sound solution for the car to put **: 1. The volume on the car navigation device or mobile phone is not turned on, and it can be turned on.

2. The programming of some mobile phones (such as iPhone) is not connected with the docking code of some models, so it can only be answered**can not be heard**, and the Bluetooth ** frequency band needs to be replaced. 3. If you don't have the car Bluetooth turned on, you need to set it to turn it on. 4. The ** audio on the mobile phone is not turned off, resulting in signal interference from the Bluetooth function.

You can connect the car through the Bluetooth of the mobile phone, so as to realize the **mobile phone**, the specific operation steps are as follows: 1. Open the multi** settings of the car and select the [Bluetooth] function. 2. Turn on the Bluetooth connection function of the car.

If the mobile phone has been connected, it can be directly through the mobile phone**, and if it has not been connected, click [Device Registration]. 3. In the Bluetooth device reminder on the car screen, tap Yes to confirm. Note:

Phone Bluetooth must be turned on and set to visible. 4. In the pop-up interface, follow the prompt information to connect the Bluetooth on the mobile phone. 5. After completing the registration of the Bluetooth of the mobile phone, select the connection switch of the device.

The car stereo suddenly has no sound, first check whether the power supply of the CD player is normal, as long as there is an electric indicator light, it should be on, and the CD cabin can also be switched on and off normally. If there is no power, please check the power supply, that is, whether the fuse box is connected to the line. The most basic condition of car audio is to have the function of playing back sound, mainly including the main unit, speakers, and power amplifiers.

1. Poor contact with sockets and signal wires. Check that the speaker is energized and that the signal lines are in good contact.

2. The most common fault of the power amplifier is the bad capacitor or burning the power amplifier tube, which is a problem of use, but most of them are unstable of the equipment itself.

3. Some power amplifiers will have a channel without sound failure, the problem is still the circuit problem inside.

4. As for other faults, there are other problems such as bad contact of power amplifier volume potentiometer, unbalanced left and right channels, too frequent protection function, poor contact of the rear panel working transfer switch and signal socket, in short, power amplifier is a kind of electrical equipment that is more prone to failure in the audio system.

Summary. In this case, you should first see if the recorder host can be turned on, whether the screen is lit, the screen is not lit, and check the safety and the rear line. The radio is turned on normally, which is caused by the damage of the speaker line, the problem of the speaker itself and the power amplifier module inside the tape recorder, which requires unplugging the plug behind the tape recorder and measuring the resistance value of the speaker, which is normal at 4 6 ohms.

Beyond this range, you will need to replace the horn and check the door position cables. These places are good, indicating that the recorder host is broken, just find the master of automotive electronics to repair it, the general charge for repairing the host is 200 yuan, and no money will be charged if it is not repaired.

Hello. Sometimes the car doesn't ring overnight, and the next day it rings, and sometimes it doesn't work.

In this case, you should first see if the recorder host can be turned on, whether the calendar screen is lit, the screen is not lit, and check the safety and the rear line. The radio is often turned on, it is caused by the damage of the speaker line, the problem of the speaker itself and the appearance of the power amplifier module inside the tape recorder, this kind of emotional situation needs to unplug the rear of the tape recorder, and measure the resistance value of the horn, which is normal at 4 6 ohms. Beyond this range, you will need to replace the horn and check the door position cables.

These places are good, indicating that the recorder host is broken, just find the master of automotive electronics to repair it, the general charge for repairing the host is 200 yuan, and no money will be charged if it is not repaired.

According to what I said, check first to see if the display screen can be lit, it's normal, but if there is no sound, it may be that the individual horns are damaged and the power amplifier is protected by the head of the local mode, measure the resistance value of the speaker, and replace the speaker with a new one if the range is exceeded.

The screens are all good, and the sound lines are also good.

It's all checked.

It's just that the host didn't check.

That is the problem of the host, just replace the power leakage amplifier module inside the host to return to the beam pin, the power amplifier module due to poor heat dissipation or other problems caused by the unstable work of the slag will occur this fault.

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, happy with your question. All the stereos on the car are not loud, and it is generally a problem with the power amplifier. Repair plan 1

Check the power supply and negative pole on the power amplifier, the power supply is normal, the negative pole is normal, and the power supply is also normal when the ignition switch is turned on, then replace the power amplifier. 2.In most models, the amplifier is integrated with the radio.

In some models, the amplifier and radio are separated. For example, Audi. Land rover.

The amplifiers are in the rear trunk. 3.If only one speaker doesn't sound.

Summary. There is no sound failure in the vehicle's audio, the relevant reasons are as follows, first, first check whether there is a problem with the fuse corresponding to the central control screen of the vehicle, if the fuse is connected or the fuse is problematic, it will also lead to this phenomenon. In this case, it is recommended to replace the fuse with a new one.

Second, this phenomenon is caused by the problem of the vehicle's central control screen program, if it is the central control screen that comes with the original car, this is the need to go to the 4S shop to upgrade the central control screen, or to refresh the third, if the central control screen is installed later, this is in the corner, see if there is an RST reset hole, poke it with a thin hard thing, press for 5 to 10 seconds to reset the fourth, the fault performance caused by the problem of the motherboard capacitor or CPU inside the central control screen, This is the place where you need to go to the car electrical appliances or navigation, disassemble the central control screen, and check the internal motherboard and CPU. Finally, check whether there is a short circuit in the relevant connection line plug or door horn? If there is a problem with one speaker, it will also cause all the speakers to make no sound.

How to always have a display in the center console.

Finally, check whether there is a short circuit in the connecting line plug or the door horn that is connected to each other. If there is a problem with one speaker, it will also cause all the speakers to make no sound.

Right. I didn't know it was a radio switch.

There is no display.

If you are not in front of the car? Shoot a radio's **.

**Can't send it.

This should be possible to send the live ** directly.

No, I can't. The button to adjust the sound is pressed and held normally to turn off the radio. Or cut off the negative pole of the battery line.

What causes no sound in car stereo? There is no sound in the car audio, the reason is that the socket contact is poor, the signal line is poor, and the car battery has a power loss, so it is necessary to check whether the audio is energized and whether the signal line is in good contact, if the car battery is in deficit, the battery should be replenished or replaced in time. Workaround:

Check whether the settings are muted first, and then try to test whether the radio and CD have sound, check whether the power supply of the CD player is normal, the light should be on when there is power, if there is no power, please check the power supply, that is, the problem between the fuse box and the line. If there is no effect, it is recommended to go to the 4S shop or repair shop to check and deal with the disadvantages without affecting the morning driving. Check that the CD nacelle should be able to switch normally, if there is no electricity, check the power supply, that is, the fuse box and the line, if there is electricity, consider whether it is a modified audio, if so, check the modified fuse, if not, check whether the audio output line is disconnected, generally do not consider the speaker failure at the same time.
