6. Troubleshooting & Maintenance

 No image on 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 display and ensure their 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 all

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.

Please contact Technical Support of your director for a solution to these issues.

 Color lose or poor picture quality:



Ensure that the HDMI cables used for both the source and transmitter and the

receiver and display are properly connected and are of good quality. Test the

HDMI cables directly from a source to display and ensure their 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 authorized dealer or our technical support.
