3.3、system control process：
After connect the AC power input (we use 3 pins power jack，the GND pin must ground
well).first of all ,standby power works，signal mainboard takes 5V-ST power supply， the
powers of PW113 begin to work，LED turns red. Resetting after V18、V33 power is normal，
PW113 initializes the system， sends STANDBY （L） signal， which controls main power begins to
work，other power VT9、VT5、AVCC、PVDD、AVDD、OVCC、CVCC、PVCC、DAVCC、
AVDD、 AVCC、 DVDA、 PVDD also work normally.MST9885、 VPC3230、 SiI161B、 DS90CF383
take proper power supply. Moreover LED signal control LED to turn yellow and glitter，it is said
that it controls normally 。At last LVDSON signal from 43pin of PW113is high，it let
DS90CF383 begin to work。After this it is in normal work state，input source is last time
source before power off。
3.3.1、when choice VGA mode by remote device ，PW113 controls MST9885 by I
bus，enable SiI161B and VPC3230，let them work in low consume mode，which can save power
and reduce interfere。At the moment VGASEL signal from PW113 output parks VGA input
channel
in PI5V330. If VGA signal inputs, MST9885 outputs Horizontal and Vertical Sync
signal and data signal，and send to PW113，which outputs format commutation data . After
DS90CF383(DS transmitter)， it transforms to the signal fitting the PDP panel demand； because
SiI161B、DS90CF383 both in normal work state，when DVI signal inputs, display video；if no
VGA signal， MST9885 can not output digital Horizontal and Vertical Sync signal ， after examined
by PW113,displays pc icon on the left and top of PDP panel ，other part display black. If no
input after 60 sec, it hints to enter "save power mode" 。At the moment , MST9885 in normal
work state， examines VGA signal ceaselessly， so it can arouse automatically in VGA mode. It is
said that when VGA signal inputs, it can work normally from standby state。
3.3.2、when in TV／AV／YCbCr mode by remote device，PW113 controls VPC3230 by
2
Cbus，otherwise PW113 controls MST9885 on the fly （output in high impedance state）by
I

I
Cbus.Because tuner N901、VPC3230、 DS90CF383 all in normal work state，when video
signal inputs， PDP panel display normally； if no video signal input， under the control of PW113，
PDP panel displays blue background，if no signal 15 mins，power off automatically and into
standby state. It can not arouse automatically。
3.3.3、When in DVI(digital RGB) mode by remote device，PW113 controls SiI161B，and
enables VPC3230， and let it working in low consume mode， otherwise PW113 controls MST9885
on the fly（output in high impedance state）by I
normal work state，when DVI signal inputs, display video；if no DVI signal，SiI161B do not
output digital Horizontal and Vertical Sync signal ，after examined by PW113,displays DVI icon
on the left and top of PDP panel ， other part display black. If no input after 60 sec, it hints to
enter "save power mode"work state。At the moment ,SiI161B in normal work state， examines
DVI signal ceaselessly，so it can arouse automatically in DVI mode. It is said that when DVI
signal inputs, it can work normally from standby state。
