How to solve the problem that the headrest DVD player has no sound?

Some guests report that the player has no sound when playing the disc. After collecting this feedback, we discovered that many of them are not operating properly.

1. The most common reason is that the IR and FM functions are activated. When these two are on, the speakers are automatically muted, so IR and FM need to be turned off first.

2. When the headphone jack is connected, the speaker will be automatically muted. Check whether the headphones are connected and the headphones need to be unplugged.

3. In silent mode, you can adjust the volume of the device to the maximum.

4. When the first three steps are completed, insert the headphones into the headphones hole when playing the disc and listen to the sound in the headphones. If the headphones have the sound, it may be the problem with the speaker. If there is no sound from the headphones, the problem may be with the motherboard.
