What are the reasons why the TV has no sound?
What are the reasons why the TV has no sound?
. The mute or audio amplifier is broken.
. The audio cable is not connected properly or is connected incorrectly.
. Digital set-top box failure.
. The sound circuit or line is faulty.
Phenomenon: There is suddenly no sound when the TV is in use, but other functions such as images are fine.
First, check whether the settings are correct. First, check whether the mute button on the remote control is pressed. Secondly, check whether the volume is adjusted to the correct position. Again, check the signal source. For wired signals, you can check whether the audio standard of the remote control is in /standard (Shenzhen users are in the standard). Adjust the channel button of the set-top box or satellite receiver to the left channel, and check whether the audio cable is connected correctly.
Second, listen to the noise. If the loud noise is caused by the offset of the audio intermediate frequency, you can change the audio intermediate frequency or fine-tune the audio intermediate frequency to restore the sound. If the noise is very small, it is not a sound intermediate frequency fault. Check the sound power amplifier part to see if the performance of the power amplifier block or peripheral components has deteriorated. If you don't understand electronics, don't move around to avoid unnecessary losses. Ask a professional to check it.
