14. Troubleshooting
Generally, the majority of HD 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. Should you encounter any technical
difficulties when installing and configuring the MX-
0808-HDBT, we are confident solutions can be found by
working through the following troubleshooting checklist
before seeking alternative technical support.
No Picture or poor quality picture
1) Power
– are your HDBT transmitter or display receiver
baluns powered both ends? Transmitters and receivers
should have their own power source i.e. the 5v power
adaptors included with your baluns.
Note:
Receivers do not need to be independently powered
if part of an HDBT extender set – there is a two core power
link between transmitter and receiver that powers the
receiver at the display end.
Are all sources definitely powered and firmly connected?
2)
If possible, always use test equipment prior to installation and
to troubleshoot any problems.

3) Distance
–
Is your cable too long for the signal to be
transmitted effectively? HDBT allows transmission of
1080p up to 100m (328ft) so make sure you cable distance
matches your requirements and is well within the maximum
transmission distance of the signal.
Note:
If you are approaching the limits of the transmission
capabilities, you will need to use a Wyrestorm HDBT
Extender set in your set up for the signal to transmit
effectively.
4) Cable joins?
Joins in your cable run can impact on signal
strength, resulting in reduced transmission that may manifest
itself in poor picture quality or a complete lack of picture.
5)
Signal Reduction
–
Are you using stranded patch leads as
interconnects between patch panels or wall outlets? Such
use reduces signal strength – we recommend solid core
straight through connections to be used wherever possible.
6)
Resolution
– If you reduce the resolution of the source,
do you get a picture? If so, this suggests a discrepancy
between source and display resolution or a bandwidth
capacity issue with your cable. Check that your inputs and
outputs share the same resolution and that the signal is
being successfully transmitted along your cable run.
7)
Correct connection
– It may seem obvious but double
check all UTP, HDMI, power and IR cables are connected to
the correct ports.
Note: Even a fraction off can be the difference between
a perfect picture and a blank screen. Double check all
connections are firmly made in the correct ports.
9)
Cable wired to 568B standard?
Is your cable wired and
terminated correctly and are those terminations connected to
the correct ports?
10)
Electrical interference –
HDBT is less susceptible to
interference compared to regular transmissions but the
location of cables and devices should be considered - could
any form of interference be generated? If so, attempt to
remove the source of electrical interference or move the
cable run to decrease the effects of the interference.
11)
Do you get a picture if you connect the source directly to the
display? If not then the problem could lie with the input or
output device rather than the means of distribution i.e. the
cable or matrix itself.
12)
HDMI lead condition and quality –
HDMI cables and
connectors are delicate and can be damaged much easier
than component or coax cable. Furthermore, lead quality
varies dramatically, particularly in lower price brackets. Swap
your HDMI leads and check operation – damage to or quality
of your leads could be the problem. If in doubt, swap them
over. Always take care inserting and extracting your HDMI
from matrix ports so as not to damage the connectors or
ports.
13)
Picture snow/HD ‘noise’ –
represents a poorly established
signal that may be caused by poor quality terminations or
excessive cable lengths. Try swapping the display adaptors
from a location you know is functioning properly or swapping
the outputs of the matrix switch used.
