Check the PSU connection to the VN-MATRIX Decoder
.
Check for ‘green’ light on the PSU
.
Check mains cabl
e,
fuse and supply
.
POWER/THERMAL FAUL
T
The unit has shut down due to either a power supply fault or over temperature condition
.
Check for obstructed ventilation grilles,
excessive ambient

e.
Cycle the power off and on to reset the uni
t.
If the problem recurs and ambient temperature is within limit
s,
try
using
a different PSU

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 loos
e/
incorrect
connections or faulty cables between the Decoder and the displa
y.
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 forma
t.
Message Displayed… “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 networ
k/
communication problems
.
Check for loos
e/
incorrect connections or faulty cables between the source
and the Encode
r.
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 loos
e/
incorrect connections or faulty cables between the Decoder
and the displa
y.
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
”.
Message Displayed… “No Matching Output Mode
”
The Decoder is receiving a data stream but is unable to find an output mode that matches the source forma
t. 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 blac
k)
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 compressio
n/
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.
