Why is there no sound on my BenQ SL461A Digital Signage?
- RRichard BeanAug 14, 2025
If you can see the picture but cannot hear any sound on your BenQ Digital Signage, there are several possible reasons: 1. The source signal cable may not be properly connected. Ensure that both video and sound inputs are correctly connected. 2. The volume might be turned down. Press the [VOL UP] or [VOL DOWN] button to adjust the sound. 3. [MUTE] may be activated. Deactivate MUTE using the [MUTE] button. 4. External speakers might not be connected. Connect external speakers and adjust the volume accordingly.
