Error Codes in the UltraRes Control Software
Error Code | Meaning |
AC Power Supply | One of the two AC power supplies |
1 Failure | is not working properly. |
AC Power Supply |
|
2 Failure |
|
AC Power Supplies | Both power supplies are not |
1 and 2 Failure | working. |
DC Power Supply | One of the |
Failure | the main board of the display has |
| failed. |
FPGA Initialization | One of the FPGAs on the main |
Failure | board did not start up correctly. |
Calibration | The main board could not |
EEPROM Failure | communicate with the calibration |
| EEPROM. |
Display Behavior and Solution
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.
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.
The display will not start up if this occurs.
Solution: The main board needs to be replaced.
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.
It is likely that the calibration EEPROM cable is disconnected. Solution: Connect the EEPROM cable.
