7. Troubleshooting
If you encounter issues with your HDMI extender, refer to the following common troubleshooting steps:
- No Picture/Signal:
- Ensure all HDMI and Ethernet cables are securely connected.
- Verify that the power adapter is correctly connected to the Transmitter unit and that the power indicator light is on.
- Check if the HDMI source device and display are powered on and set to the correct input.
- Test the HDMI cables directly between the source and display to rule out cable issues.
- Ensure the Ethernet cable is a Cat5e/6/7 cable and is not damaged. Try a shorter cable if possible.
- Reduce the resolution of the source device to see if a signal is established.
- IR Remote Control Not Working:
- Ensure the IR Blaster is positioned directly over the IR sensor of the source device.
- Ensure the IR Receiver is positioned to receive signals from your remote control.
- Check that the IR cables are securely plugged into the correct ports on both the Transmitter and Receiver units.
- Verify that the remote control itself is functioning correctly (e.g., fresh batteries).
- Poor Picture Quality/Flickering:
- Use a high-quality Cat6 or Cat7 Ethernet cable, especially for longer distances.
- Ensure the Ethernet cable is not running parallel to power lines or other sources of electromagnetic interference.
- Check if the resolution and refresh rate of the source device are within the supported specifications of the extender and display.
