What is the reason for the intermittent sound of smart TV?

General causes and treatment methods for TV sets without sound:

1、It is possible to accidentally press the mute button on the remote control by mistake,Thus turning the TV into silent mode,So that there will be no sound suddenly,In this case, you only need to press the mute button again,You can restore the sound of the TV**。

2. There is a problem with the signal source or program source of the TV. When connecting to the TV set-top box, plug the audio cables of the left and right channels in the opposite direction, or the cable contacts poorly and loosely. Check the connection of the thread, unplug it and plug it in again, and then fix it well.

If you have a problem with the program source itself, you can change the channel to see if other channels have sound.

3. Hardware failure of the TV. There is a problem with the internal parts of the TV, such as broken speakers, short circuits or open circuits in the internal circuitry, or faulty motherboards and other components. At this time, you need to call the after-sales service of the TV**, and ask professional maintenance personnel to carry out a comprehensive overhaul of the TV.

Extended Materials. Smart TV has a picture and a silent solution to solve the problem:

Step 1: In the signal source interface**Whether there is sound, no sound, you can try to turn up the volume of the external device and the volume of the TV;

Step 2: Power off and let stand for a few minutes before restarting the TV attempt. There is still no sound after adjusting the volume,Remove the external device,Check if the TV itself can be normal**Sound(such as turning on the key tone attempt(Settings-System settings-Adjust in sound),**LETV source attempt, etc.)。

First, there is a problem with your remote control, or it is possible that you have pressed the volume button of the remote control by mistake. Is it that the sound card plug of your TV is not in good contact, and it is easy to intermittently have no sound.

Not married and single for life.

Because the signal source input is unstable and may cause intermittent sound, it can generally be solved by reconnecting the signal source line, such as connecting the cable TV signal, then replugging the cable TV signal line behind the TV, such as connecting the digital TV set-top box, then check whether the connection line between the set-top box and the set-top box is unblocked.

If it's an IPTV of a telecom, then there is a problem with the network speed.

If it's a digital set-top box for radio and television, you see if every channel is the same.

It is estimated that there is a high probability that there is a problem with the signal source, and then there is the set-top box.

Contradictory! This is definitely a problem with the signal origin!!

If there is no sound on the smart TV, it may be that the settings are wrong,Mute the sound or turn the sound to the minimum,There may also be that the volume is too low due to the unconnected audio cable,It may also be a power strip failure。 1、Check whether the setting is wrong,When you encounter a TV with an image but no sound,First of all, you can see if there is a problem with the TV mute setting。 When the user uses the TV remote control, does he press the mute setting of the remote control, if he presses the mute setting, the TV will definitely have no sound when it is used.

2. Check whether the audio cable is not connected, the TV needs to connect the audio cable on the TV before use, the audio line of the TV is composed of two parts: the audio cable and the connector, when the TV has no sound, you need to reconnect the audio cable of the TV. 3. The volume adjustment is too small, and when using the TV ** program, adjust the volume of the TV or set-top box to the minimum. As a result, there is no sound on the TV, and the volume of the TV or set-top box should be adjusted again during troubleshooting.

4. When the power strip of the TV fails, it will also cause the TV to have no sound. When the power strip of the TV fails, the first thing you should troubleshoot is the power strip of the TV.

If there is a situation where the TV sometimes has sound and sometimes does not, it is recommended to deal with it in the following ways: 1. There is a problem with the signal source input of the TV, resulting in the sound coming and going, such as the connection between the TV and the cable TV signal line, set-top box or *** machine, etc., which is loose and poorly contacted; Generally, it can be solved by reconnecting and fixing it; 2. There is a problem with the current program source of the TV, which causes the sound to come and go, which can generally be solved by switching other program channels or changing the video disc**; 3. The hardware failure of the TV causes the sound to come and go, such as the failure of the speaker of the TV, the unstable circuit connection between the speaker and the motherboard, or the failure of the motherboard and its parts. Generally, it is recommended to contact the after-sales service of the TV to overhaul the TV to solve the problem. 100 times more attentive, 10 points satisfied.

Is there a set-top box, if there is, unplug the set-top box, connect the DVD player, if the sound is normal......The description is a problem with the set-top box. If it is normal, open the shell to check the TV, whether the power supply of the sound power amplifier comes and goes, if so, please repair the switch transformer pins and other parts, and the fault can be eliminated.
