Error Codes in the UltraRes Control Software

Error Code Meaning Display Behavior and Solution
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.
