Samsung BN44-00195 PSU Schematic

PFC Voltage Booster circuits.
When QB851 turns on by the
PS_ON ( = about +3V) signal
form the main board, Transistor
in OPTO PC80s is then turn on,
which will turn on QB802, which
will supply VCC for PFC IC
Controller ICP801S, that is
when the DC gets boosted up
by the MOSFET QP801S,
Diode D802, Inductor LP801.
