Error Codes in the UltraRes Control Software

Error Code Meaning Display Behavior and Solution
AC Power Supply
1 Failure One of the two AC power supplies
is not working properly. The backlight will be dimmed to a
maximum setting of 10, which is
necessary in order to reduce
power consumption.
Solution : Replace the failing
power supply.
AC Power Supply
2 Failure
AC Power Supplies
1 and 2 Failure Both power supplies are not
working. The issue could be either the AC
power supplies or the standby
power board.
Solution : First check the AC
power status cable to make sure
it’s connected.
Solution : If you have checked the
connections and both power
supplies are still not working, we
recommend replacing the entire
power tray.
DC Power Supply
Failure One of the DC-DC converters on
the main board of the display has
failed. The display will not start up if this
occurs.
Solution : The main board needs
to be replaced.
FPGA Initialization
Failure One of the FPGAs on the main
board did not start up correctly. There are two possible causes: one
of the FPGAs has corrupt code or
is damaged.
Solution : First check the FPGA
status LEDs on the main board. If
one is not blinking, that FPGA
didn’t start up. The FPGA code
may need to be programmed
again.
Solution : If reprogramming an
FPGA doesn’t work, it is likely the
FPGA is damaged. If this is the
case, the main board needs to be
replaced.
Calibration
EEPROM Failure The main board could not
communicate with the calibration
EEPROM. It is likely that the calibration
EEPROM cable is disconnected.
Solution : Connect the EEPROM
cable.
