  If there's no sound, first, ensure the mute function isn't enabled by pressing the MUTE button on the remote. Check that the stereo cable for audio units and the speaker wires are connected properly; defective cables could also be the cause. Make sure the correct input source is selected using the INPUT selector on the front panel or the remote. Finally, verify that the SPEAKERS selector is correctly set to A, B, or A+B.

  If your Yamaha Amplifier isn't turning on, make sure the power cable is fully connected. If using the remote, ensure you're pressing POWER on the front panel to ON. If the issue persists, there may be an internal problem; disconnect the AC power cable and contact an authorized Yamaha dealer or service center. If you notice any unusual smells or noises, do not turn the power on and seek professional repair.
