To Next PageTo Next PageWhy does the sound suddenly go off on my Yamaha RX-V459?
The sound on your Yamaha Receiver might suddenly go off due to: * Activation of the protection circuitry because of a short circuit. Check that the speaker impedance setting is correct. * The sleep timer turning off the unit. Turn on the unit, and play the source again. * The sound being muted. Press MUTE or VOLUME +/– on the remote control to resume audio output.
Why is no sound heard from the subwoofer of my Yamaha RX-V459?
If you are not hearing sound from the subwoofer connected to your Yamaha Receiver, it could be due to the following: * If “BASS OUT” in “SET MENU” is set to “FRNT” when a Dolby Digital or DTS signal is being played, set “BASS OUT” in “SET MENU” to “SWFR” or “FRNT” when a 2-channel source is being played. * The source may not contain low-frequency bass signals.
Why no sound from subwoofer on Yamaha RX-V459 Receiver?
If you're not hearing any sound from the subwoofer on your Yamaha Receiver, particularly when playing a Dolby Digital or DTS signal, check the “BASS OUT” setting in the “SET MENU.” It should be set to “SWFR.” If you are playing a 2-channel source, you can set “BASS OUT” to “FRNT”. Also, the source material may not contain low-frequency bass signals.
Why is there no sound from the center speaker on my Yamaha RX-V459 Receiver?
If you're not hearing sound from the center speaker of your Yamaha Receiver, first check that “CENTER” in “SET MENU” is set to either “SML” or “LRG”, not “NONE”. If you've selected one of the HiFi DSP programs (excluding 6ch Stereo), try another sound field program. Also, make sure that “SUR. LR” in “SET MENU” is set to “SML” or “LRG”. Verify that the cables are correctly connected and not defective. Finally, adjust the “SPEAKER LEVEL” settings.
What to do if my Yamaha RX-V459 fails to turn on or enters standby mode?
If your Yamaha Receiver fails to turn on or enters standby mode shortly after being powered on, consider the following: 1. Ensure the power cable is firmly connected. 2. Verify the speaker impedance setting matches your speakers. Adjust if necessary. 3. Check speaker wire connections for any shorts or loose strands. Ensure wires only touch their respective connections. 4. If the unit experienced a strong electric shock, set it to standby, disconnect the power cable for 30 seconds, then reconnect and try again.
How to fix sound only coming from one speaker on my Yamaha RX-V459?
If sound is only coming from one speaker on your Yamaha Receiver, consider these potential causes: * When playing a monaural source with a CINEMA DSP program, the source signal may be directed to the center channel. Try another sound field program. * Check if “CENTER” in “SET MENU” is set to “NONE”. If so, set it to “SML” or “LRG”. * If one of the HiFi DSP programs (except for 6ch Stereo) has been selected, try another sound field program. * Verify that “SUR. LR” in “SET MENU” is not set to “NONE”. If it is, set it to “SML” or “LRG”. * Incorrect cable connections can cause this issue. Connect the cables properly. If the problem persists, the cables may be defective. * Incorrect settings in “SPEAKER LEVEL” can also be the cause. Adjust the “SPEAKER LEVEL” settings.
What to do if Dolby Digital or DTS sources cannot be played on Yamaha Receiver?
If Dolby Digital or DTS sources cannot be played on your Yamaha Receiver (the Dolby Digital or DTS indicator in the front panel display does not light up), check the following: * Ensure the connected component is set to output Dolby Digital or DTS digital signals by following the operating instructions for your component. * Verify that “INPUT MODE” is set to “AUTO” or “DTS,” and not “ANALOG.”
How to fix a Yamaha RX-V459 that fails to turn on?
If your Yamaha Receiver fails to turn on or enters standby mode shortly after being powered on, several factors could be responsible. Start by ensuring the power cable is firmly connected. An incorrect speaker impedance setting can also cause this; adjust it to match your speakers. The protection circuitry might have been activated, so verify all speaker wire connections are secure and not touching anything they shouldn't. Lastly, if the unit experienced a strong electric shock, set it to standby, disconnect the power cable for 30 seconds, and then reconnect it.
What to do if Yamaha RX-V459 Receiver sound suddenly goes off?
If your Yamaha Receiver suddenly goes off, it could be due to a few reasons. The protection circuitry might have been activated due to a short circuit, so check that the speaker impedance setting is correct. Alternatively, the sleep timer might have turned off the unit; if so, turn it back on and play the source again. Lastly, the sound could be muted. Press MUTE or VOLUME +/– on the remote control to resume audio output.
How to fix no sound from surround speakers on Yamaha Receiver?
If you're not getting any sound from the surround speakers on your Yamaha Receiver, and the unit is in “STRAIGHT” mode while playing a monaural source, press STRAIGHT (EFFECT) on the front panel to disable “STRAIGHT” mode. Also, if “SUR. LR” in “SET MENU” is set to “NONE”, “SUR. B” is automatically set to “NONE”. Set “SUR. B” to “SML” or “LRG”.
