What to do if my Yamaha Stereo Receiver has no sound?
First, ensure that the output cords are correctly connected; if the problem continues, the cords may be defective. Also, be sure to press the input selector that corresponds to your input source.
How to fix Yamaha RX-460 FM stereo reception when it is noisy?
Noisy FM stereo reception can occur when the transmitter is too far away or the antenna input is poor. Check your antenna connections and consider using a multiple element FM antenna to improve reception for your Yamaha Stereo Receiver.
Why does my Yamaha Stereo Receiver sound “hums”?
Humming sounds from your Yamaha Stereo Receiver can be due to incorrect cord connections. Ensure the audio plugs are firmly connected. Also, if using a turntable, make sure it is properly connected to the GND terminal on the receiver. If problem persists, the cord may be defective.
What to do if only one side speaker outputs the sound on my Yamaha Stereo Receiver?
If you're only getting sound from one speaker, first check the BALANCE control and adjust it to the correct position. Also, verify that the speaker cords are connected properly. If the problem persists, the cables may be defective.
Why is there distortion on my Yamaha RX-460 even with a good FM antenna?
Distortion even with a good FM antenna is likely due to multipath interference. Try adjusting the antenna placement to minimize this interference for your Yamaha Stereo Receiver.
Why can't I tune in a desired station with Auto tuning on my Yamaha RX-460?
If you cannot tune into a desired station using Auto tuning on your Yamaha Stereo Receiver, it could be due to a weak signal or loose antenna connections. Try using Manual tuning mode. For AM, tighten the loop antenna connections and rotate it for best reception.
Why are there continuous crackling and hissing noises coming from my Yamaha RX-460?
Continuous crackling and hissing noises in your Yamaha Stereo Receiver can be caused by interference from lightning, fluorescent lamps, motors, thermostats, and other electrical equipment. Using an outdoor antenna and a ground wire may help reduce the noise, but it's difficult to eliminate it entirely.
Why is the distance decreased within which the Yamaha RX-460 Stereo Receiver remote control transmitter can be used?
If the range of your Yamaha Stereo Receiver's remote control has decreased, the batteries are likely weak. Replace them with new ones.
Why are there buzzing and whining noises coming from my Yamaha RX-460 Stereo Receiver?
Buzzing and whining noises, especially in the evening, may be caused by a nearby television set. Try moving the television away from your Yamaha Stereo Receiver.
Why is the volume level low while playing a record on my Yamaha RX-460 Stereo Receiver?
If the volume level is low when playing a record on your Yamaha Stereo Receiver, and you're using a turntable with an MC cartridge, the player should be connected to the receiver through the MC head amplifier.
