Here are some troubleshooting steps you can follow if you are not getting any image on the display when using the techlogix TL-TP70-HD2ARC 70m Extender:

1. **Check Display Input:** Ensure that the display device is set to the correct input source where the extender is connected.

2. **Check HDMI Cables:** Make sure that the HDMI cables used for both the source/transmitter and the receiver/display are properly connected and in good working condition. Test the HDMI cables directly from a source to display to confirm their functionality.

3. **Inspect Cat5e/Cat6 Cable:** Verify that the Cat5e/Cat6 cable has not been damaged and has been terminated correctly with T568B on both ends. You can use a temporary length of Cat5e/Cat6 for testing compatibility and functionality.

4. **Grounding:** Ensure proper grounding of the power supply to prevent any electrical issues.

5. **HDMI 1.2 Source Devices:** If you are using older HDMI 1.2 source devices, compatibility issues may arise. Contact Technical Support for assistance in resolving these problems.

6. **Color Loss or Poor Picture Quality:** If you experience color loss or poor picture quality, check the HDMI cables for quality and proper connections. Also, ensure proper grounding of the power supply to avoid signal interference.

7. **Improper Grounding:** If the signal becomes stronger or picture quality worsens when connecting video connectors, it could be due to improper grounding. Check and ensure all components are properly grounded to a common ground.

If the issue persists after following these troubleshooting steps, it is recommended to seek further assistance from an authorized dealer or tech support as mentioned in the user manual.
