Note: Pins are monitor microprocessor pins unless otherwise specified (IC2003).
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.
Note: Pins are monitor microprocessor pins unless otherwise specified (IC2003).
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).
DET_12V(34pin): Abnormal (L). Main 12V is not applied.
If error is detected during start-up or operation, the power is turned on again by polling.
DET_D3V3(35pin): abnormal (L). Digital 3.3V is not applied.
If error is detected during start-up or operation, the power is turned on again by polling.
Note: Basically, debug print logs are analyzed or communication logs
are analyzed by a bus monitor.
Initial communication from the main CPU is not received. (Request for the
monitor model No. is not received.)
→ Communication line failure or main CPU start-up failure
Start-up reason confirmation from the main CPU cannot be received. (Start-
up communication until start-up reason notification command is not
received.)
→ Main CPU start-up failure or monitor microprocessor reception failure
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
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
Note: Pins are monitor microprocessor pins unless otherwise specified
(IC2003).
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.

Details are displayed on page 1/16 of the adjustment process for the main micropro-
cessor.
