How to solve the problem of projector displaying sound?

It is a common fault that the projector displays sound, which may be caused by many reasons. Solving this problem requires the following steps:

1. Check the device connection.

First, check whether the equipment is connected correctly. Please make sure that the cable is connected correctly and securely. If you use an HDMI cable, make sure that the cable is not damaged and plugged into the correct socket.

2. Check the volume setting

Check the volume settings of the projector and accessories. Make sure the volume is not set to Mute or Minimum Volume. Make sure the volume is set correctly and check that the mute function is turned on.

The projector needs to know whether the sound input of the media device comes from the projector itself or from other input sources. Carefully check whether the source settings of the device are correct.

4. Check the audio cable

Check whether the audio cable is properly connected to the device and ensure that the audio cable is not damaged or outdated.

Check the projector

If the problem still appears after checking the settings and connection of the projector according to the above steps, try restarting the projector or adjusting different audio settings to find a solution. If this problem cannot be solved, you may need to seek the help of senior technicians.

In short, if you find a sound problem with the projector, you should first check the connection, volume setting and sound source setting, then check the audio line, and finally restart the projector. If all these steps are fruitless, you need to check and solve the problem further.
