      There might be several reasons why your Yamaha Receiver isn't producing sound. Ensure the correct input source is selected. The unit might not be able to reproduce the input signal, so check 'Signal Info' in the 'Option' menu. Verify that audio output to Zone A (or Zone B) is enabled by sliding the Zone switch to the correct zone. Finally, check the cable connecting the unit and playback device; if defective, replace it.

      If your Yamaha Receiver isn't responding to the remote control, first ensure you're within the operating range. Then, replace the batteries with new ones. Check if direct sunlight or strong lighting is interfering with the unit's remote control sensor; if so, adjust the lighting or reposition the unit. Also, verify that the remote control IDs of the unit and the remote are identical. Lastly, ensure the remote control is set to the Zone A operation mode.

    Why does my Yamaha Receiver keep turning off?

      Samuel BennettAug 23, 2025
      Your Yamaha Receiver might be entering standby mode automatically due to several reasons. The sleep timer may have activated; if so, turn the unit back on. The auto-standby function could be enabled; to disable it, set “Auto Power Standby” in the “Setup” menu to “Off”. The speaker impedance setting might be incorrect; set it to match your speakers. Finally, a short circuit could have activated the protection circuitry; twist the bare wires of each speaker cable firmly and reconnect them to the unit and speakers.

      If your Yamaha Receiver is unresponsive, the internal microcomputer may be frozen due to an external electric shock (like lightning) or a drop in the power supply voltage. Hold down the power button on the front panel for more than 15 seconds to reboot the unit. If the problem continues, disconnect the power cable from the AC wall outlet and plug it back in.

    Why don't the colored keys work on my Yamaha RXA670 Receiver remote?
    • T
      Troy JohnsonSep 3, 2025
      The colored keys on your Yamaha Receiver remote may not be working because the connected HDMI device doesn't support their operation. Use a device that supports the operation of the RED/GREEN/YELLOW/BLUE keys. Alternatively, the settings of these keys may have been changed; set the “Remote Color Key” settings in the “Setup” menu to “Default”.

    How to fix Yamaha Receiver that won't turn on?
    • C
      Chelsea YoungSep 5, 2025
      The power may not turn on because the protection circuitry has been activated three times consecutively. When this happens, the standby indicator on the unit blinks when you try to turn on the power. As a safety precaution, the capability to turn on the power is disabled. Contact your nearest Yamaha dealer or service center to request repair.
