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.
