2) Inverter/Lamp failure details (Power red LED flashes once and OPC (preset) LED flashes)
3) Power failure details (Power red LED flashes twice and OPC (preset) LED flashes)
4) Communication failure details (Power green LED flashes once and OPC (preset) LED flashes)
5) Other failure details (Power green LED flashes twice and OPC (preset) LED flashes)
Error type
OPC (preset) LED operation (1 cycle)
Lamp failure
Flashes once
H: On
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 moni-
toring process. (For the first time, only the inverter is reset, and error OFF is not acti-
vated.)
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.
L: Off
Error type
OPC (preset) LED operation (1 cycle)
PS_ON
AC_DET fail-
ure Flashes 
once
H: On
AC_DET(72pin: Abnormal (L).
If error is detected during start-up or operation, the power is turned on again by inter-
rupt handling (instantaneous blackout processing).
L: Off
D_POW
Main 12V fail-
ure Flashes 
twice
H: On
DET_12V(34pin): Abnormal (L). Main 12V is not applied.
L: Off
If error is detected during start-up or operation, the power is turned on again by polling.
D_POW
Digital 3.3V 
Failure 
Flashes 3 
times
H: On
DET_D3V3(35pin): abnormal (L). Digital 3.3V is not applied.
L: Off
If error is detected during start-up or operation, the power is turned on again by polling.
Error type
OPC (preset) LED operation (1 cycle)
Note: Basically, debug print logs are analyzed or communication logs 
are analyzed by a bus monitor.
Initial communi-
cation reception

up communication until start-up reason notification command is not 
received.)
→ Main CPU start-up failure or monitor microprocessor reception failure
L: Off
Regular commu-
nication failure 
Flashes 3 times
H: On
Regular communication that is performed at 1 second intervals in the nor-
mal operation is interrupted.
→ Main CPU operation failure or monitor microprocessor reception failure
L: Off
Other communi-
cation failure 
Flashes 5 times
H: On
When a request (PM_REQ=H) is sent from the main microprocessor, the 
request command is not output from the main CPU, etc.
→ Main CPU operation failure or monitor microprocessor reception failure
L: Off

OPC (preset) LED operation (1 cycle)
Monitor temper-
ature failure
Flashes once
H: On
If the panel temperature is 60
°C or more for 15 seconds or more in a row, CAUTION 
appears on the OSD (flashes in red in the lower right screen).
If the panel temperature is 60
°C or more for 25 seconds or more in a row, error 
standby is activated.
