FAQs: Troubleshooting & Solutions of 4K Extender

Q1. How do I troubleshoot a ​black screen on my 4K RX device?

QuoteIf you are experiencing a black screen on your 4K RX device, first check the resolution settings. If the default output resolution is set to 3840x2160p, and the display does not support 4K, the black screen may occur. In this case, try lowering the output resolution to 1080P or 720P by pressing and holding the RST button on the RX device for about 1 second to switch to different resolution outputs automatically. If the issue persists, it may be helpful to check the connections, cables, and power source to ensure they are properly connected and functioning. If the problem continues, contacting technical support for further assistance may be necessary.

Q2. How do I address the issue of my RX device always displaying "Connect to TX"?

Quote
If your RX device is continuously displaying "Connect to TX," the following steps may help resolve the issue:
  1. Ensure that the TX (transmitter) device is powered on and operating normally. Verify its connections and power source.
  2. If the image is stuck at the RX (receiver), try shortening the transmission distance between the TX and RX devices. This can help improve the stability of the signal transmission.
If the problem persists after following these troubleshooting steps, consider checking the cables, connections, and settings on both the TX and RX devices. It may also be beneficial to consult the user manual or contact technical support for further assistance.

Q3. How can I address the issue of my RX device always displaying "No Signal Input"?

Quote
If your RX device constantly displays "No Signal Input," the following steps can help troubleshoot the issue:
  1. Check if the HDMI output from the signal source (e.g., a media player, gaming console, or other device) is normal. Ensure that the signal source is powered on and functioning properly.
  2. Confirm if the output resolution from the signal source is within the supported range of the RX device. If the output resolution exceeds the supported range, it may result in a "No Signal Input" message. Adjust the output resolution of the signal source if necessary.
  3. Verify that the signal source is securely connected to the HDMI IN port of the TX (transmitter) device. Ensure that the HDMI cable is properly connected and functional.
By performing these checks, you can troubleshoot common issues that may cause the "No Signal Input" message on the RX device. If the problem persists, consider examining the HDMI cables, connections, and settings as well as contacting technical support for further assistance.

Q4. How do I address the issue of my RX device always displaying "No Match"?

Quote
If your RX device consistently displays "No Match," it indicates that the TX (transmitter) and RX (receiver) devices are not paired. Here are steps to address this issue:
  1. Pairing: The TX and RX devices should be paired to establish a connection. By default, they are typically factory-paired. If the devices have been reset to factory settings or if you are adding a new receiver, re-pairing the devices is necessary.
  2. Re-pairing Process: To re-pair the devices, please refer to Quick Start of 4K Extender.
  3. Factory Settings: If you need to restore factory settings on the devices, be aware that re-pairing will likely be required after this process.
By re-pairing the devices according to the above instructions, you can address the "No Match" issue displayed on the RX device. If further assistance is needed, consider reaching out to technical support for guidance.

Q5. How can I address the issue of short transmission distance for my wireless devices?

Quote
If you are experiencing a weak signal or short transmission distance with your wireless devices, consider the following steps to improve the signal strength:
  1. Adjust Antenna Angle or Device Placement: For devices with adjustable antennas, try varying the angle to optimize signal reception. Additionally, repositioning the devices within the space may improve signal strength, especially if obstacles are obstructing the signal path.
  2. Signal Penetration: Keep in mind that wireless signals may struggle to penetrate reinforced concrete floors, load-bearing walls, elevator shafts, and metal surfaces, as these materials can reflect or block the signal. Repositioning the devices to minimize obstruction and maximize line of sight between the transmitter and receiver can help improve signal strength.
  3. Channel Congestion: If multiple sets of wireless devices are operating in the same area, adjust the WIFI channel to avoid channel congestion. This can help mitigate interference and improve signal reliability.
By following these guidelines, you can potentially enhance the signal strength and transmission distance of your wireless devices. If the issue persists, consider consulting the user manual or contacting technical support for further assistance.

Q6. How can I address the issue of a frozen screen on my device?

Quote
If you are experiencing a frozen screen on your device, consider the following steps to troubleshoot and resolve the issue:
  1. Weak Signal: If the screen freeze is due to a weak signal, adjust the angle of the antenna to be vertical to the ground to optimize signal reception. Additionally, consider repositioning the device to a location that provides better access to the wireless signal.
  2. Unavailable Signal Resolution (1080i): If the 1080i resolution is unavailable due to abnormal signal, you can try switching to 1080P or 720P resolution settings on your device to see if this resolves the issue.
  3. Channel Congestion: If multiple sets of devices are operating simultaneously, adjust the WIFI channel to avoid channel congestion. This can help prevent interference and potentially resolve issues related to the frozen screen.
By following these troubleshooting steps, you may be able to address the frozen screen issue on your device. If the problem persists, refer to the user manual for additional guidance or consider reaching out to technical support for further assistance.

Q7. How can I address the issue of "Infrared Return Invalid" on my device?

Quote
If you encounter the "Infrared Return Invalid" issue with your device, follow these steps to troubleshoot and address the problem:
  1. IR Receiving Line: Ensure that the IR receiving line is correctly plugged into the TX (transmitter) device. Verify that the connection is secure and properly seated.
  2. Proximity to IR Receiving Head: Place the IR receiving head in close proximity to the remote control receiving head of your set-top box or DVD player. This proximity is essential for effective transmission of IR remote control signals.
  3. Remote Control: Please note that while the device is capable of transmitting IR remote control signals, no remote control is provided by default. You will need to use your existing remote control devices with the system for IR signal transmission.
By following these steps, you can effectively address the "Infrared Return Invalid" issue. If the problem persists, consult the user manual for further guidance or consider reaching out to technical support for assistance.

Q8. How can I address the issue of "Failure of HDMI Loopout" on my device?

Quote
If you're experiencing the "HDMI Loopout Failed" issue, please follow these steps to troubleshoot and possibly resolve the problem:
  1. Check HDMI Connection: Ensure that the HDMI cable is securely connected to the HDMI OUT port of the TX (transmitter) device. Verify that the cable is properly inserted and making a solid connection.
  2. Cable Integrity: Inspect the HDMI cable for any signs of damage, such as frayed or bent connectors. If there is physical damage to the cable, replace it with a new one to rule out any connectivity issues.
  3. Test Alternative HDMI Devices: If possible, try using a different HDMI cable or connecting to an alternative HDMI output device to determine if the issue is specific to the current setup.
By following these steps, you can troubleshoot and potentially resolve the "HDMI Loopout Failed" issue. If the problem persists, consult the user manual for additional troubleshooting steps, or consider reaching out to technical support for further assistance.
