Display Behavior and Solution
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.
