Pins are monitor microprocessor pins.
ERR_PNL (IC1001: pin 100): Abnormal ÒLÓ. (detected only when the backlight is illuminated).
Note that after five detection counts, the lamp cannot be activated except in the monitoring process. Accumulated counts are cleared
to 0 when the corresponding setting in the monitor processing is made or after continuous illumination for 30 minutes.
Flow: INV_ERR (P3203: pin 5) -> CPU (IC1001: pin 100)
Refer to "2) Power failure details."
NON
VSYNC (IC1001: pin 71): ÒLÓ pulse every 16 ms when normal (interrupt).
The panel temperature remains 60¡C or higher for 15 seconds or more: CAUTION flashes red in the lower right of the OSD for AVC.
The panel temperature remains 60¡C or higher for over 25 seconds or more: error standby
(OSTEMP of OTHER2 in the monitoring process: displaying the thermistor AD value, TEMP ERR on FAN page: changing the AD
value for abnormal temperature): thermistor

CPLD1 (IC1014: pin 41): Abnormal ÒLÓ. 5V for the LCD panel is not achieved.
Flow: PNL5V (Main PWB P1801: pins 7, 8 and 9) -> Power supply detection IC (IC1810) -> CPLD1 (IC1014: pin 41)
Detected only when the panel is operated.
CPLD2 (IC1503: pin 97): Abnormal ÒLÓ. Inverter 5V is not achieved.
Flow: 5V regulator (IC1809) -> Gate IC (IC3203) -> CPLD2 (IC1503: pin 97)
Detected only when the inverter is illuminated.
