TROUBLESHOOTING
Generally, the majority of AV distribution installation issues are either caused by minor
connection errors, communication problems between devices, or when the transmission of
high signal bandwidth is attempted using insufficient cable or exceeding distance capabilities
of the cable. Should you encounter any technical difficulties when installing this product,
solutions can be found by working through the following troubleshooting checklist before
seeking alternative technical support.
1) Power – is your unit powered with LED indication? Check connectivity.
NOTE: This device is not compatible with 5V USB power - please use included power
adaptor only.
2) Check display device supports HDCP, is switched to the correct source input mode and is
compatible with connected devices - if any issue is suspected, replace display with another
model.
3) Distance – Is the HDMI cable too long for the signal to be transmitted effectively? Check
Specification for HDMI input and out transmission distance capabilities and do not exceed
recommended distances.
NOTE: If approaching limits of the HDMI transmission capabilities between source/
receiver and display, up to 3 units can be daisy-chained to extend transmission.
Care should be taken that only the final unit in the chain has the settings on - previous units
should be set to PASSTHROUGH.
4) Correct connection – double check all HDMI, power and audio mini-jack cables are
connected to the correct ports. Even a fraction off can be the difference between a perfect
picture and a blank screen.
5) HDMI lead condition and quality - Swap HDMI cables and check operation – damage to
or quality of your cables could be the problem. Always take care inserting and extracting your
HDMI cables from ports so as not to damage the connectors or ports.
6) Picture speckles/HD ‘noise’ – represents a poorly established signal that may be caused
by poor quality or excessive HDMI cable lengths. Try swapping the display adaptors from a
location that is functioning properly or swapping the outputs of any matrix switch used. HD
Noise (NO image) may be an HDCP Issue between the source and display but poor cabling
can also cause this due to poor communication.
7) Blu-ray: 3D – is the equipment being used 3D enabled? Is a 3D disc being played in a 3D
enabled Blu-ray player or through a compatible AV receiver?
8) 4K - Are you trying to upscale 1080I such as a Sky or Cable box to 4K? this cannot be
achieved with only a 1080I source/signal.
