To perform a factory reset on the Onkyo TX SR501, turn off the unit, then press and hold the 'Video 1' button while pressing the 'Standby/On' button. Release when 'Clear' appears on the display.
Check that the speaker cables are properly connected, the correct input source is selected, and that the 'Mute' function is not activated. Also, ensure the volume level is turned up.
Use an HDMI cable to connect the HDMI output on the receiver to an HDMI input on the TV. Alternatively, use component or composite cables if your TV does not support HDMI.
This may be due to overheating or a short in the speaker wires. Ensure the receiver is well-ventilated and check that all speaker wires are correctly connected and not shorting out.
The Onkyo TX SR501 does not support firmware updates as it is an older model. Ensure you have the latest manual and support documents for troubleshooting.
The Onkyo TX SR501 does not have built-in Bluetooth support. You can use an external Bluetooth adapter connected via the audio input to stream audio.
Use a soft, dry cloth to clean the exterior. Avoid using harsh chemicals or abrasive materials. Ensure the unit is turned off and unplugged before cleaning.
Consult the manual for speaker placement guidelines. Use the built-in test tone feature to adjust speaker levels and ensure consistent sound output.
First, replace the batteries in the remote. If the issue persists, ensure there are no obstructions between the remote and the receiver, and try resetting the remote by removing the batteries for a few minutes.
Use the available audio inputs such as AUX, CD, or Tape. Ensure that you select the correct input source on the receiver when playing audio from these components.
