If you are not receiving AM stations on your Onkyo Receiver, make sure that the included AM loop antenna is connected to the AM antenna terminals.
Why is there no sound from the subwoofer connected to my Onkyo Receiver?
If you experience no sound or very low volume from the subwoofer connected to your Onkyo Receiver, check the subwoofer mode setting. Ensure that the subwoofer mode is not set to “OFF”.
How to eliminate hum or low-frequency noise from my Onkyo HT-R490 Receiver?
If you are experiencing hum or low-frequency noise with your Onkyo Receiver, check the outer conductor of the input plugs. Additionally, adjust the placement of the audio connection cables on the rear panel to potentially reduce the hum.
Why is there no sound from the center speaker of my Onkyo HT-R490 Receiver?
If you get no sound from the center speaker, or very minimal sound from it when using your Onkyo Receiver, check that the speaker cable is correctly connected between the receiver and the speaker. If the listening mode is set to STEREO or ORCHESTRA, the center speaker outputs only the effect sound. Set the speaker configuration to 3 ch or 5 ch, if it is set to 2 ch or 4 ch.
Why does no picture appear on the TV screen when using my Onkyo HT-R490?
If no picture appears on the TV screen (or monitor) when using your Onkyo Receiver, first ensure that the TV (or monitor) is set to receive the input from the receiver. Also, check that the video cable is securely connected.
