This issue may arise from incorrect cable connections, so ensure the cables are properly connected; if the problem continues, the cables might be defective. Also, check the BALANCE control setting and adjust it to the appropriate position.
Why Yamaha RX-397 Stereo Receiver has no sound?
Check the input and output cable connections to ensure they are properly connected; if the problem persists, the cables may be defective. Verify that an appropriate input source has been selected using the INPUT selector on the front panel or the remote control. Make sure the TAPE MONITOR function is turned off and the SPEAKERS A/B switches are correctly set. Finally, ensure that the speaker connections are secure.
How to fix a Yamaha Stereo Receiver that fails to turn on?
If your Yamaha Stereo Receiver doesn't turn on, several things could be happening. First, ensure the power cord is firmly connected. Check that the impedance setting matches your speakers. Also, verify that the speaker wires aren't touching each other, as this can activate the protection circuitry; if this happens, check the wires and then turn the power back on. Confirm that the IMPEDANCE SELECTOR switch on the rear panel is set correctly. Lastly, if the unit experienced a strong electric shock, set it to standby, unplug it for 30 seconds, and then plug it back in.
What to do if the Yamaha RX-397 remote control is not working?
If the remote control for your Yamaha Stereo Receiver isn't working, make sure you're within a 6-meter range and no more than 30 degrees off-axis from the receiver's front panel. Check if direct sunlight or bright lighting is interfering with the remote control sensor; if so, reposition the unit. Finally, replace all the batteries in the remote, if they are weak.
What to do if the automatic tuning method on Yamaha RX-397 doesn't tune to the desired station?
If the automatic tuning method fails, it could be due to a weak signal or loose antenna connections. Ensure the AM loop antenna connections are tight and orient it for the best reception. Also, try using the manual tuning method.
Why can't I tune in previously preset stations on my Yamaha RX-397?
If you can no longer tune into previously preset stations on your Yamaha Stereo Receiver, it's likely the unit has been disconnected for an extended period. You'll need to preset the stations again.
Why can't the volume level be increased, or why is the sound distorted on my Yamaha RX-397 Stereo Receiver?
If the volume level cannot be increased or the sound is distorted on your Yamaha Stereo Receiver, the component connected to the TAPE OUT or the MD OUT jacks might be turned off. Turn on the power of that component.
Why is the sound degraded when listening with headphones connected to the CD player or the tape deck connected to this Yamaha RX-397?
If the sound quality is poor when listening through headphones connected to a CD player or tape deck via your Yamaha Stereo Receiver, the receiver itself might be turned off or in standby mode. Turn on the power of the receiver.
Why is there a lack of bass and no ambience on my Yamaha RX-397 Stereo Receiver?
If you notice a lack of bass and ambience with your Yamaha Stereo Receiver, check that the + and – wires are connected correctly at both the amplifier and the speakers. Ensure the speaker wires are connected to the correct + and – phase.
Why is the sound level low on my Yamaha RX-397 Stereo Receiver?
If the sound level is low on your Yamaha Stereo Receiver, check if the LOUDNESS control is engaged. If it is, set the LOUDNESS control to the FLAT position.
