Display Troubleshooting
3 or more
modules out
in a line within
the same PLR
section
1. Check the modules at the beginning and
end of the affected area. This issue can be
caused by disconnected or bad SATA cables
on both of those modules. If the module power
indicator is on, there is most likely a SATA
cable issue. If the module power indicator
light is off, check the power supplies for the
modules at each end of the issue are on. If
not power or signal, it is most likely a module
issue.
2. Measure the site power to verify it meets
Daktronics requirements. If this issue is only
seen with white or light-colored content,
there is most likely a power issue. If there is
insufficient power, work with an electrician to
establish proper site power.
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.
