Outline: Communication/Power failure detected by the monitor microprocessor (IC2002) is stored on EEPROM,
states can be confirmed in the adjustment process mode.

Error type
Power LED operation (1 cycle)
Note: Pins are monitor microprocessor pins (IC2002).
Inverter/Lamp failure
Red flashes once
H: Red On
L: Off
Refer to “Inverter/Lamp failure details”. OPC_LED flashes by 
pressing the [MENU] key on the remote control.
Power failure
Red flashes twice
H: Red On
L: Off
Refer to “Power failure details”. OPC_LED flashes by pressing the 
[MENU] key on the remote control.
Communication 
failure with main
CPU
Green flashes once
H: Green On
L: Off
Refer to “Communication failure details”. OPC_LED flashes by 
pressing [MENU] key on the remote control.
Communication line failure or main CPU communication failure.
Others
Green flashes twice
H: Green On
L: Off
Refer to “Other failure details”. OPC_LED flashes by pressing the 
[MENU] key on the remote control.
Error type
OPC (preset) LED operation (1 cycle)
Note: Pins are monitor microprocessor pins unless otherwise 
specified (IC2002).
Lamp failure
Flashes once
H: On
L: Off
ERR_PNL(40pin): Abnormal L. Confirmed after 5 consecutive 
detections at 1 second intervals (detected only when the backlight 
is on).
Note that after five detection counts, the lamp cannot be activated 
except in the monitoring process. (For the first time, only the 
inverter is reset, and error OFF is not activated.)
Accumulated counts are cleared to 0 when the setting in the 
adjustment process is made, when AC_ON is performed with 
[CH_DOWN] and [VOL_UP] on the unit down or after continuous 
illumination for 3 minutes.
