  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.
