F. Power Supply
F-1. Rectifier And Filter Ckt:
The 90Vac-265Vac input line voltage is rectified by D901- D904, and smoothed by C906 to provide
DC operating voltage for the circuit.
F-2. Flyback And Pwm Ckt :
When power is initially applied to the circuit,C909 charges through R903, Q902.When the voltage
across C909 reaches a level of 16V, U901 is enabled, turning on Q901 and turning off Q902 to
complete start-up action.
During the On-time of Q901, energy is stored in T900. At this time the polarity of the output windings
is such that all output rectifiers are reverse biased and no energy is transferred. Primary current is
sensed by R914 and compared to a DC level that is determined by voltage feedback. When this
level is reached, Q901 is turned off and the polarity of all T900 windings reverses , forward biasing
the output rectifiers. All the energy stored is now transferred to the output capacitors. Many cycles
of this store/release action are needed to charge the outputs to their respective voltages.
The voltage across C949 is fed through a voltage divider R984,R985,R986, R987 and VR980 to the
error amplifier U980 and compared to an internal 2.5V reference ,then determine the feed back
level of U901 PIN1.
F-3. Snubber Ckt:
Energy stored in the leakage inductance of T900 cause a voltage spike which be added to the
normal reset voltage across T900 when Q901 turn off. The clamp consisting of D905, R904 and
C907 limits this voltage excursion from exceeding the Vds rating of Q901. In addition, a turn off
snubber made up of D906, R905 and C908 keeps power dissipation in Q901 low by delaying the
voltage rise until drain current has decreased from its peak value. This snubber also damps out any
ringing which may occur due to parasitic.
F-4. Synchronized Ckt:
The oscillator frequency is defined by R912 , C920. The equation is approximately : Fosc=1.8/
(R912*C920). The external signal “SYN+ & SYN−”
that comes from horizontal circuit T802 can synchronize the working frequency of power circuit Via
ZD903,R918,R919 and R916.
F-5. Power Saving Ckt:
The monitor has ON, Suspend/Standby and OFF states.The monitor enters Suspend/Standby
mode if either V-sync or H-sync signals are removed.When the machine in the Suspend/Standby
State, PS1 should be low to turn off +15Vs. In this state, input power should be less than 15W and
D960 LED illuminate yellow. The monitor enters OFF mode if both H-sync and V-sync are removed.
When in the OFF State, PS1 and PS2 should below simultaneously to turn off +15Vs and +8.3Vs
outputs. In this state, input power should be less than 5W and D960 LED illuminate amber.
15
Page 17
F-6. Degauss Ckt
The DEGU signal which comes from micro-p to control degauss coil act or not.
When DEGU is high, Q950 will be saturated to make RL901 working, AC line provides
a degaussing current to degauss coil.
F-7. OVERLOAD PROTECTION CKT
The primary current flows through the current sensing resistor R914. The voltage drop on R914 will
be rectified by D927 and keep a dc level on C927 that is dependent on the output power. When this
DC level reach the trigger voltage of Q920 , the pin1 of U901 goes low and the power stage is
immediately switched off.
F-8. BROWN – OUT CKT
When the input voltage down below the setting level (85Vac-75 Vac), Q904 will be supplied a trigger
voltage to make Q920 turn on ,and this time, power supply shall be shut down.
G. Deflection
G-1. Sync Rpocessor:
H-sync & V-sync or input to U1(u-P), then u-P output the H-out & V-out to
U401(TDA4858).
G-2. Hor. Processor & Vert. Pre-Amp

Hor . processor
The H-out that come from u-P will input to the pin 15 of U401,it will be compared
with the oscillator sawtooth voltage by the PLL1(pin 26) phase detector, After that, it will be
compared again with the flyback pulse (pin 1) by the PLL2. The PLL2 detector thus compensates
for the delay in the external horizontal deflection circuit by adjusting the phase of the HDRV(pin 7)
output pulse.
