How to solve the problem without sound in the stereo?

There is no sound in the stereo and the solutions are: poor connection of the audio power supply, poor connection of the audio source and problems with the audio input.

1. The power of the stereo is not connected properly.

Or there is something wrong with the power supply. When checking the power interface of the stereo, pay attention to whether the interface is loose and ensure that the power cord and plug are not damaged.

2. The stereo sound source is not connected well.

Or there is something wrong with the sound source. Audio sources can be mobile phones, computers, stereos, televisions, etc. Check whether the output end of the audio source is connected to the input end of the audio, and ensure that there is no problem with the audio source.

3. There is something wrong with the stereo input.

If there is something wrong with the input end of the audio, the signal of the sound source cannot be transmitted to the output end of the audio, resulting in no sound. You should check whether the input of the stereo is damaged and make sure that the input is not blocked by sundries.

Introduction of common audio problems and solutions;

1, the sound can be played normally, but there will be "crackling" noise from time to time. There is no other noise when the computer uses headphones, but when using the speaker, it will make a "beep" sound from time to time, sometimes for a long time, sometimes for a short time.

Solution: Replace the new power socket with good quality.

2. The sound can be played normally, but if the bass is adjusted, there will be a "thunderclap" noise in the speaker, which is unbearable. Sometimes there will be a "thunderclap" noise when some speakers are used, especially when the subwoofer knob is turned, the situation will be more serious. Because it was caused by turning the bass button, it is certain that the bass potentiometer is damaged.

Solution: It is simple to deal with this problem, just change a new potentiometer.
