Remarks
The pin is a monitor microcomputer pin.
ERR_PNL(40pin): L abnormal. It fixes it by five time of the spacing
continuous agreement for one second.
(It detects it only while back light is lighting.)
Attention of no start by five times of accumulation excluding monitor
step.
(The 1st time doesn't make an error-off only by inverter reset.)
The number of times of accumulation is a setup at Process A, or it is
cleared zero times in AC_ON, main board [CH_DOWN]+[VOL_UP]
pushing, or continuation lighting 3 minutes.
OPEN error of LED device.
The LED device was out of order, and the number of breakdowns
exceeded the definite value.
(It doesn't drop in the error even if the threshold is not installed, and
the breakdown of the LED device occurs in the current state.)
Temperature error when temperature maximum value in LED driver's
detection LED panel exceeds threshold.
State when temperature in LED driver exceeds threshold.
(LED back light shuts down compulsorily when the temperature in the
LED driver exceeds the threshold.)
Remarks
The pin is a monitor microcomputer pin.
AC_DET(72pin) abnormal (L).
The during starting detection is an error standby. The detection when
operating is polling and a power supply reboot.
15V_CHK(71pin) abnormal (L). Main 15V has not risen.
The during starting detection is an error standby. The detection when
operating is polling and a power supply reboot.
DET_D3V3(59pin) abnormal (L). Digital 3.3V has not risen.
The during starting detection is an error standby. The detection when
operating is polling and a power supply reboot.
DET_PNL12V(58pin) abnormal (L). Panel power has not risen.
The detection when the during starting is detected, and it operates is
polling and an error standby.
LED backlight 3.3V power abnormal (LED T-CON detection → It noti-
fies to a sub microcomputer via main CPU.) microprocessor is
informed via the main CPU.)
Error standby when detecting it
LED backlight 42V power abnormal (LED T-CON detection → It noti-
fies to a sub microcomputer via main CPU.)
Error standby when detecting it.
