UNLITFLASHING
NO POWER
Check the PSU connection to the
VN-MATRIX Decoder.
Check for ‘green’ light on the PSU.
Check mains cable, fuse and supply.
POWER/THERMAL FAULT
The unit has shut down due to either a
power supply fault or over temperature
condition.
Check for obstructed ventilation
grilles, excessive ambient
temperature.
Cycle the power off and on to reset
the unit.
If the problem recurs and ambient
temperature is within limits, try using
a different PSU.
NO SOURCE SELECTED, ENCODER
OFFLINE (Nodata Splash disabled)
SOURCE DATASTREAM BEING
RECEIVED
Check that the source is not
outputting a ‘blank’ signal.
Check that the display is powered
and not in standby mode.
Check for loose/incorrect
connections or faulty cables between
the Decoder and the display.
If the display has multiple inputs,
check that the correct input is
selected.
If there are setup options for the
display input, check that these are
appropriate for the Decoder output
format.
Check that the display is compatible
with the Decoder output format.

“No Source Datastream”
Source image is stable
but has a color cast
Source image is unstable
or corrupted
Displayed image is
frozen.
Check that the Decoder has a source selected.
Check that the Decoder is not in disabled or standby mode.
Check that the corresponding Encoder device is operating and set up
correctly by following the Source Checkup.
Check for network/communication problems.
Check for loose/incorrect connections or faulty cables between the source
and the Encoder.
Check that the visual disruption is not on the original source signal.
Check to see if the Encoder local monitor has the same color cast.
If so, check that the correct color space has been applied to the source.
Check for loose/incorrect connections or faulty cables between the Decoder
and the display.
Check that the original source itself is not frozen.
If the source is OK, the likely cause is that the source datastream has been
interrupted and the Nodata Splash option is disabled. This will result in the
Decoder displaying the last valid source frame received. Follow the checks
above for “No Source Datastream”.

“No Matching Output
Mode”
The Decoder is receiving a data stream but is unable to find an output mode
that matches the source format. Most likely cause is that the Encoder is
using a custom input mode for which there is no matching output mode on
the Decoder. If this is the case you will need to create a custom output mode.
Image is stable but ‘drops
out’ (goes black) or
freezes intermittently
Check that the visual disruption is not on the original source signal.
The image disruption could be caused by data packets being lost. There
may be insufficient network bandwidth available resulting from high network
traffic or poor network performance. Try increasing the compression settings
or adjusting the bandwidth limitation settings on the Encoder.
Displayed image is
noticeably poorer quality
than the source, either in
terms of clarity or refresh
rate.
The compression/bandwidth limitation settings on the Encoder may be set
too high. Try decreasing the compression settings or adjusting the
bandwidth limitation settings on the Encoder.
