Appendix C. Trouble Shooting
C.1 Problem solving
The power switch should illuminate red whenever mains power is supplied. Always make sure
that power is connected before using the problem solving guide.
A spare fuse is provided in the IEC mains connector before the unit leaves the factory. Always
replace the fuse with one of the correct value as shown in the Installation section.
In the event of a power supply failure, there is front panel and remote panel indication. The
second supply is able to sustain operation of the unit until it can be removed from service and
the fault rectified.
The table in section C.1.1 provides some sample faults and their solutions.
For faults outside these, contact the Snell Customer Service desk.
C.1.1 Sample problems and their solutions
There in no video output
Check that there is power to the unit and that it is turned on.
Check that the video output resolution is not beyond the capability of the display. (see
answer to question below).
An output should be seen once the unit has booted.
The image appears fuzzy or lacking clarity
If an analog or digital LCD/Plasma screen is used, check that the output resolution of
the MV-16 is the same as the native resolution of the panel. This will avoid forcing the
screen to rescale the image. Most LCD/Plasma screens produce artifacts when their
internal scalars are active.
Output resolution is set using the Screen Resolution function under the System menu.
The image is not centered in the screen
Use the monitor controls to align the image.
If an analog LCD screen is used use the auto-adjust facility.
Unit fails to respond correctly to commands
Power cycle the unit and/or perform a Master Reset. A Master Reset will restore all
settings to the factory default. Turn off the power for a few seconds, then turn it back on
while pressing both Fade/Function buttons during boot up. Follow any required
configuration steps after reset.
Can digital audio be balanced or unbalanced?
Yes.
AES/EBU inputs may be jumper selected per channel to be either balanced or
unbalanced inputs. The settings are set via jumpers on each digital audio input card as
explained in the installation section.
