How to troubleshoot no sound from Yamaha speakers or subwoofer?
- E
  Eduardo HarveyJul 28, 2025
  If you are experiencing no sound from your Yamaha speakers or subwoofer, here are a few things you can check: * Ensure the AC power cord is firmly plugged into the wall outlet. * Verify the main power switch on the subwoofer is set to ON. * Check that all connections are secure, and try using a different cable. * Increase the volume by turning the instrument’s MASTER VOLUME control to the right. * Adjust the subwoofer BASS control to the right to increase the volume. * Make sure the level of the signal being input is not too low by turning up the volume on the instrument.
