11.4 Module and Power Supply Diagnostics
Each module in a GalaxyPro ® GP3 display has a power supply attached to it. Each power supply
provides power only to the module it is connected to. Display modules are equipped with a
status indicator LED that can help troubleshoot possible issues. Under normal operation, the
status indicator LED should flash once every 4 seconds.
Module Self-Test
If a module is blank, but has power supplied to it, perform a module self-test to diagnose a
module or SATA cable failure. To perform a self-test, follow the steps below.
1. Attach a SATA cable to Port A
and Port B on the module, as
shown in Figure 26.
2. Disconnect the power to the
power supply for 10 seconds.
3. Reconnect the power to start
the self-test.
4. Verify the module is running a
self-test.
Remove the SATA cable and cycle
power to the module to stop the self-
test.
