Why is the sound degraded when using headphones with my Yamaha RX-497?
If the sound is degraded when listening with headphones connected to the CD player or tape deck connected to your Yamaha Stereo Receiver, the unit may be turned off or in standby mode. Turn on the power of the unit.
Why Yamaha RX-497 Stereo Receiver can no longer tune in preset stations?
If previously preset stations can no longer be tuned in on your Yamaha Stereo Receiver, it's possible the unit has been disconnected for an extended period. You will need to preset the stations again.
Why Yamaha RX-497 Stereo Receiver has continuous crackling and hissing noises?
Continuous crackling and hissing noises in your Yamaha Stereo Receiver can be caused by external electrical equipment such as lightning, fluorescent lamps, motors, or thermostats. Try using an outdoor antenna and a ground wire. This may help reduce the noise, but complete elimination is difficult.
Why is the sound level low on my Yamaha RX-497?
If the sound level is low on your Yamaha Stereo Receiver, the LOUDNESS control might be engaged. Set the LOUDNESS control to the FLAT position.
What to do if Yamaha Stereo Receiver cannot tune in desired station?
If you're having trouble tuning into a station with your Yamaha Stereo Receiver's automatic tuning, the signal may be weak, or the antenna connections might be loose. Tighten the AM loop antenna connections and orient it for the best reception. You can also try using the manual tuning method.
Why does my Yamaha RX-497 lack bass and ambience?
If you're experiencing a lack of bass and ambience with your Yamaha Stereo Receiver, the + and – wires may be connected in reverse at either the amplifier or the speakers. Ensure that the speaker wires are connected to the correct + and – phase.
Why is my Yamaha RX-497 making a humming sound?
A humming sound from your Yamaha Stereo Receiver can be caused by incorrect cable connections. Ensure that the audio plugs are firmly connected; if the problem persists, the cables may be defective. Also, check if the turntable is properly connected to the GND terminal; if not, make the GND connection between the turntable and the unit.
Why only one speaker works on my Yamaha RX-497?
If you're only hearing sound from one speaker with your Yamaha Stereo Receiver, it could be due to incorrect cable connections. Ensure that all cables are properly connected; if the problem persists, the cables may be defective. Another possibility is an incorrect setting for the BALANCE control. Adjust the BALANCE control to the appropriate position.
How to fix noisy FM stereo reception on Yamaha RX-497?
Noisy FM stereo reception on your Yamaha Stereo Receiver can often be attributed to the distance from the transmitter or a poor antenna input. Check the antenna connections and consider using a high-quality directional FM antenna. You might also try using the manual tuning method.
Why Yamaha RX-497 Stereo Receiver remote control does not work?
If the remote control for your Yamaha Stereo Receiver isn't working correctly, consider these possibilities: ensure you're within a 6-meter range and 30 degrees off-axis from the front panel. Check for direct sunlight or strong lighting hitting the receiver's remote sensor and reposition the unit if necessary. Replace the batteries, as weak batteries can cause issues. Also, verify that the remote control ID matches the unit's ID. If not, switch either the remote control ID or the unit’s ID. If problems persist, try setting another code of the same manufacturer using 'LIST OF REMOTE CONTROL CODES'.
