How to tune out the sound of Changhong TV?

1. Check whether the settings are correct. Check if the tone is muted and check the red and white lines of the audio.

Whether it's a mistake, or if you switch the channel. Whether the volume is too low, the TV remote control should also be adjusted to a certain volume.

2. Listen to the noise. If the noise is loud due to the shift of the mid-frequency of the accompanying sound, you can change the mid-frequency of the accompaniment or fine-tune the mid-frequency of the accompaniment to restore the sound. If the noise is very small, it is not a fault of the accompanying intermediate frequency, check the accompanying power amplifier part to see if the performance of the amplifier block or peripheral components has deteriorated.

After installing a digital TV set-top box, the TV has no sound.

2. If the wiring is good, the problem lies in the following two situations: one is the set-top box problem. If the set-top box is newly installed, this possibility is very large. The second is the signal reason. Poor signal reception can easily cause the audio-visual effect of the TV.

After connecting the computer to the Changhong TV, there is no sound on the TV.

Since the wired way to connect the computer with the Changhong TV is simply by an HDMI or VGA cable.

The above is the solution to the no-sound fault caused by non-hardware damage of Changhong TV。 And many times,Changhong TV has no sound because of poor internal contact or aging circuits。 However, in view of the uneven understanding of electronic circuits by users,For the personal safety of users,It is not recommended that users check the internal circuit of Changhong TV privately。
