Troubleshooting Steps
Content
switched
between display
sections
1.
Check the fiber interconnect cables
between the display sections because
they may be switched. Port A should be
connected to Port A. Port B should be
connected to Port B.
2.
Check the fiber cables coming from the
DMP because they may be switched.
Scattered or out
of order content
1. The SATA cable and redundant SATA
cable from the PLR to the modules may be
switched.
2. Call Daktronics help desk to verify the
translation table is correct.
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.
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.
