Gnd
(1): Pin 1 (P_ON) is (PWR_ON from Main: Turns on 12VM and
Gnd 24VS to the Main. It does not turn on T-CON 24VD or 12VT. If
the 12VM is missing, the set will click on and then click back off.
0.82V
(Shows up as 5VMNT on the Power Off Status).
0.82V
(2): Pin 18 12VT_ON) is (Panel_CTL) from Main: This turns on
0.82V
the T-CON 12VT, (which is T-CON 12VT P202 pin 7-12).
0.82V
(3): Pin 2 (DRV_ON) is (INV_ON) from Main: This turns on the
OL
T-CON 24VD, (which is also T-CON 24V P203 pins 8-15). This
Gnd
24VD is then routed directly to the Panel.
Gnd
(4): ADC (AC_DET): This pin monitors the AC input. If it is
1.03V
missing the TV will not turn on. Power_Off_by_AC_DET is
1.03V registered in the Power Off Status.
1.03V
(5): Pin 3 (DPC): Places the Power Supply in Power Saving
1.03V
Mode when APC in the Customer's Menu is turned On. (0V Off /
3.4V On)
