What to do if my Osram Sylvania SB378W has no sound?
- LLinda JohnsonAug 11, 2025
If your Osram Speaker System has no sound or the sound is weak, there might be several reasons. First, the volume level could be at the minimum; try raising it using the Vol+ button on the unit or the + button on the remote. Second, the paired device might not be playing or its volume is too low; ensure the device is playing music or a movie and its volume is set high. Finally, the input source might be incorrect; switch to the desired mode using the button on the remote or the Standby/Source button on the unit.
