The details are displayed in "ERROR STANDBY CAUSE" on page 1 of process A mode for the main microprocessor.

Initial communication from the main CPU is not received. (After canceling the reset, request for the monitor model No. is not received.)

ψ Communication line failure or main CPU start-up failure

Time-out setting and start-up mode change cannot be received from the main CPU. (Start-up communication until time-out setting and start-up mode change is not received.)

Basically, communication logs are analyzed by a bus monitor or debug print logs are analyzed.

ψ Main CPU start-up failure or monitor microprocessor's reception failure

Regular communication that is performed at 1 second intervals in the normal operation is interrupted.

ψ Main CPU operation failure or monitor microprocessor's reception failure

L_FL_ERR (pin 73): 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 corresponding setting in the process A is made, when the power is turned on with [CH_DOWN] and [VOL_UP] on the unit down or after continuous illumination for 3 minutes.

Main microprocessor detection error (FAN error, 1bitAMP error, etc.㧕

If error is detected during operation, error standby is activated by polling.

DET_PNL5V (pin 57): Abnormal (L). Panel power is not applied.

If error is detected during operation, error standby is activated by polling.

EU_POW

PS_ON

PANEL_POW

D_POW

If error is detected during operation, error standby is activated by polling.

DET_6V (pin 27): Abnormal 㧔L). UR6V is not applied.

(MONITOR MAX TEMP on process A mode: Change of temperature failure AD value): Thermistor

DET_D3V3 (pin 62): Abnormal 㧔L). Digital 3.3V is not applied.

If error is detected during operation, error standby is activated by polling.

AC_DET (pin 31): Abnormal (L), DET_10V (pin 63). Main converter 13V/UR10V is not applied.

If error is detected during operation, the power is turned on again by interrupt handling (instantaneous blackout processing).

DET_3V3 (pin 64): Abnormal (L). Main power 3.3V is not applied.

VSYNC (pin 48) failure (uninput). Trident_IC operation failure.

Detected during operation (interruption)

If the panel temperature is 60°C or more for 15 seconds or more in a row, CAUTION appears on the OSD of AVC (flashes in red in the lower right screen).
