Troubleshooting Steps
Area of content
mixed up -
module ID out of
order
Verify the SATA cable path in that area is
correct by comparing it to the display signal
drawing. If not, correct the signal path.
Entire display
blank
1. Verify there is power to site by ensuring
the power supply indicators are on. If they
are on, there is power to site and it is most
likely a signal issue. If there is site power,
continue to Step 3.
2. Verify the contactors for each display
section are closed and allowing power to
the display and control system.
3. Verify the ProLink Router (PLR) is receiving
power. If the LED indicator lights are on,
unplug and reestablish power to the PLR.
4.
Verify the fiber cables from the Digital
Media Player (DMP) to the PLR are
connected.
5. Call Daktronics help desk at 1-877-DAK-
HELP (325-4357) and have them verify the
content that was supposed to play was
successfully uploaded and sent to the
display.
Display too
bright
1. Immediately call Daktronics help desk and
have them blank the display.
2. Verify the Multi-Direction Light Sensor
(MDLS) is connected.
3. Inspect the area for a light source shining
on the Multi-Direction Light Sensor (MDLS).
This may cause incorrect readings. If
necessary, relocate the MDLS to a different
area.
4. Verify the MDLS is mounted correctly. If
not, remount the MDLS.
5. Have the help desk verify that the MDLS is
set to multi-direction and automatic.
Display too dim
1. Verify the MDLS is connected.
2. Verify the MDLS is mounted correctly. If
not, remount the MDLS.
3. Verify there is no debris or excessive dirt
buildup on the three MDLS windows.
4. Have the help desk verify that the MDLS is
set to multi-direction and automatic.
5. Have the help desk verify the display is
not experiencing thermal dimming due to
excessive heat.
