Symptoms
You may experience the following symptoms when your Onkyo TX SR606 is showing no signal via HDMI:
- The TV displays a "No Signal" message.
- The screen is black or blank.
- Audio may still play, but no video is visible.
- The receiver lights up, but there’s no output to the TV.
Quick checks
Before diving into more complex troubleshooting, perform these quick checks:
- Ensure the TV is powered on and set to the correct HDMI input.
- Check if other devices connected to the TV work properly.
- Inspect the HDMI cable for any visible damage.
- Verify that the receiver is set to the correct source for the device you’re trying to use.
Step-by-step fix
- Power Cycle Devices: Turn off both your Onkyo receiver and TV. Unplug them from the power source for about 30 seconds, then plug them back in and power them on.
- Check HDMI Connections: Disconnect and reconnect the HDMI cable at both the receiver and TV ends. Ensure it clicks into place securely.
- Select Correct Input: On your TV remote, press the "Input" or "Source" button and select the HDMI port that your Onkyo receiver is connected to.
- Test with Another HDMI Cable: If the issue persists, try using a different HDMI cable. A certified cable can help ensure optimal performance.
- Note on firmware: The TX-SR606 is a legacy model that no longer receives firmware updates from Onkyo. If the steps above don't resolve your issue, the HDMI board may be failing — a known issue on older Onkyo receivers.
- Factory Reset: As a last resort, you can perform a factory reset on your Onkyo receiver. This will restore it to its original settings. Refer to the user manual for steps on how to do this.
If it still doesn't work
If you’ve followed all the steps and still encounter issues, it may be time to consult with a professional technician or contact Onkyo support for further assistance.
