What to do if Yamaha Receiver remote control is not working?
If the remote control for your Yamaha Receiver isn't working correctly, consider these potential causes: * Ensure you are within the remote's operational range (a maximum of 6 m (20 feet) and no more than 30 degrees off-axis from the front panel). * Replace all batteries with new ones. * Verify that the manufacture code has been correctly set and try setting another code of the same manufacturer.
What to do if Yamaha RX-V340 has no or weak sound from speakers?
If you are experiencing no sound or weak sound from particular speakers connected to your Yamaha Receiver, the cable connections may be incorrect. Connect the cables properly. If the problem persists, the cables may be defective.
How to reduce noise interference on Yamaha RX-V340?
If you're experiencing noise interference with your Yamaha Receiver, move the unit further away from digital or high-frequency equipment.
How to improve poor bass reproduction on Yamaha Receiver?
If you're experiencing poor bass reproduction with your Yamaha Receiver, try these fixes: * If “SOUND 1D BASS” on the set menu is set to SWFR or BOTH and you don't have a subwoofer, select MAIN. * Ensure the speaker mode settings (main, center, or rear) on the set menu match your speaker configuration. Select the appropriate position for each speaker based on their size.
How to stop a humming sound from Yamaha RX-V340 Receiver?
If you're hearing a humming sound from your Yamaha Receiver, ensure the audio plugs are firmly connected. If the problem continues, the cables may be defective and need replacement.
What to do if Yamaha RX-V340 Receiver does not operate properly?
If your Yamaha Receiver isn't operating properly, disconnect the AC power cord from the outlet and then plug it back in after about 30 seconds. This can resolve issues caused by external electric shocks or low voltage.
What to do if there is no sound from the subwoofer of Yamaha Receiver?
If you're not getting any sound from the subwoofer connected to your Yamaha Receiver, here's what to check: * If you're playing a Dolby Digital or DTS signal, make sure “SOUND 1D BASS” on the set menu is set to SWFR or BOTH. * If you're playing a 2-channel source, ensure “SOUND 1D BASS” on the set menu is set to BOTH.
