7. Troubleshooting & Maintenance
No image on the display:
Ensure that the display device has been set to the correct input.
Ensure that the HDMI cables used for both the Source/Transmitter and the
Receiver/Display are properly connected and are working. Test the HDMI
cables directly from a source to the display and ensure correct operation.
Ensure that the Cat5e/Cat6a cable has not been damaged and that it has been
terminated correctly with T568B on both ends. A temporary length of
Cat5e/Cat6 can be used for testing to ensure that the devices are compatible
and working properly.
Ensure proper grounding of the power supply.
Known issues with HDMI 1.2 source devices: Older compatibility (HDMI 1.2)
may result in HDBaseT transmission issues.
Colour loss or poor picture quality:
Ensure that the HDMI cables used for both the Source/Transmitter and the
Receiver/Display are properly connected and are high quality. Test the HDMI
cables directly from a source to a display to check picture quality.
Ensure proper grounding of the power supply.
If the static becomes stronger or picture quality becomes worse when
connecting the video connectors, this may be due to improper grounding.
Check the grounding and make sure all the components are properly grounded
to a common ground. Improper grounding may cause damage to the Receiver.
If your problem persists after following the above troubleshooting steps, seek further
help from your authorised dealer.
