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 DC-DC converters on
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.
