Slide 25
If the micro processor (IC8000) detected RMIN signal or Power Switch signal, it sends the
TV_SUB_ON signal to the power micom via P6 connector.
Slide 26
The signal from the power micom turns on the switching transistor Q500.
This allow F15V to be output to the DC/DC circuit on the A board.
The F15V is supplied to IC8100, IC8101, IC8704 and IC8705.
7
The voltages from these ICs are distributed to the different circuits where theyre used.
8
Next, the micro processor (IC8000) outputs PANEL_MAIN_ON signal to the power micom.

Warning: The Vsus line has large capacitors that hold the charge for some time even after the TV has been turned off and
unplugged. When disconnecting P2/SC2 or P11/SS11, bleed the remaining charge of the Vsus before reconnecting the cable.
Use a 500 ohms/ 5W (At least) resistor to discharge the Vsus line before reconnecting P2/SC2 or P11/SS11.

The Panel SOS is generated from 5 input signals
by IC5000.
These 5 inputs have different priority.
Each input signals are valid if these signal have
voltage over 2V.
Then IC5000 outputs multi level voltage
(Panel_SOS) based on inputted signals.
