Why can't the toy projector fix the sound?

If your toy projector has no sound, there may be several reasons:

1. Volume Mute: Please check whether the toy projector is muted. Some projectors may have a physical button or menu option that can be used to disable sound. Solution: Press or select the unmute option.

2. Battery is exhausted: Please check whether the battery is exhausted. Solution: Replace the battery with a brand-new battery and ensure that all batteries are installed correctly.

3. The projector volume is too low: If the battery is normal, the volume setting may be too low. Solution: After installing the battery, adjust the volume. Just follow the steps in the product manual.

4. Internal components are damaged: If the projector is normal, but the sound still does not appear, it may be because the internal components are damaged. In this case, it is best to contact the manufacturer or service center for maintenance.

In short, if you encounter the mute problem of the toy projector, you should first check whether it is mute or the battery is dead. If these are all normal, further investigation may be needed, for example, speakers or internal components may need to be replaced. If you are not sure how to deal with it, you'd better ask a professional to repair it.
