2. Product safety notice
Many electrical and mechanical parts in this chassis have special safety visual inspections
and the protection afforded by them cannot necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. Before replacing any of these components
read the parts list in this manual carefully. The use of substitute replacement parts, which do
not have the same safety characteristics as specified in the parts list, may create shock, fire,
or other hazards.
3. Service notes
z
When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
z
Keep wires away from high voltage, high temperature components and sharp edges.
z
Keep wires in their original position so as to reduce interference.
z
Adjustment of this product please refers to the user’ manual.

1.3 Electronic Circuit Theory
1.3.1 Switching Mode Power Supply
1.3.1.1 AC Current Input Circuit
P801 is a connector for connecting AC Power. F801 is a fuse to protect all the circuit. AC input
voltage is from 90v to 264V. R801 and R802 joined between two inputting main circuit to prevent man
from shock. L801 is used to clear up low frequency wave. C801 and C802 are used to discharge the
waves that L801 produced. High frequency waves are damped by C801 and C802. D801 is a rectifier
40
which composed of 4 build-in diodes, it inverts AC to DC.
1.3.1.2 High Voltage to Low Voltage Control Circuit
C804 is used to smooth the wave from rectifier. IC802 is a highly integrated PWM controller.
When rectified DC high voltage is applied to the Vcc pin during start-up, the MOSFET Q804 is initially
off, and the Vcc pin capacitor is charged. When the Vcc pin voltage reaches approximately 10V, the
control circuitry is activated and the soft-start begins. The soft-start circuit gradually increases the duty
cycle of the MOSFET from zero to the maximum value over approximately 4ms. If no external
feedback/supply current is fed into the CS pin by the end of the soft-start, the current Setpoint will be
above the fault level, FAULT flag is raised, if the FAULT duration exceeds 80ms, the output controller
disable
Resistor R808, R809, R810, R811 are for line over voltage shutdown(OVP)
When PWM is turned off, the main current flow will be consumed through R804 and D802, This
will prevent MOSFET Q804 from being damaged under large current impulse and voltage spike.
D804 and C807 to provide internal Auxiliary voltage to Vcc pin during normal operation.
Otherwise, error amplifier and feedback current input the CS pin for duty cycle control.
1.3.1.3 DC_5V and DC_14V Output Circuit
For DC 5V, D805 is used to rectify the inducted current. R828 and C814 are used to store energy
when current is reversed. The parts including C818, C822, C820,L803 are used to smooth the current
waves.
For DC 14V, D803 is used to rectify the inducted current. R827 and C813 are used to store
energy when current is reversed. The parts including C815, C817 and L802 are used to smooth the
current waves.
1.3.1.4 Feedback and OVP Protect Circuit
Pin R of IC803 is supplied 2.5-v stable voltage. It connects to 5V and 14V output through R822,
R823 and R824. R822, R823 and R824 are output sampling resistor. When the sampling voltage
more than 2.5V or less than 2.5V, current of FB IC802 will change, this can change the voltage from
T801.
OVP Protect Circuit: When output is overvoltage, the auxiliary winding voltage will be increased,
when it reaches about 14V. Q803 is triggered . It makes the IC802 Pin 1 exceed 5V, then the IC802
output will be disabled.
Q801, R816, R817 and ZD803 make up of dummy loading circuit. For start-up sequence, during
5V output take place high loading first, this dummy loading circuit operated to insure 14V not be
increased.

Inverter circuit
14VDC provides the power for IC501; the control signals Brightness and ON/OFF come from I/F
board. ON/OFF signal connect to pin8 of IC501 and makes IC501 enable. Brightness signal
connect to pin7 of IC501 and regulates the panel brightness, R510 , R511, C507 make up a
network of delaying time circuit . The striking frequency is determined by the external Resistor
R505 pin5 of IC505and r516. The operation frequency is determined by the external Resistor
R505 pin5 of IC505. the capacitor and resistrer connected to pin4 to set striking time and shunt
down delay time. BURST MODE dimming pulse frequency and duty is regulated by I/F board.
The output drives, include square pulses output of pin14,12,11 to drive MOSFET U501, U502, and
U501, U502 are N channel MOSFETs. U501 and U502 work as harf-bridge topology.Two
transformers are connected in parallel with each transformer driving two lamps in series. Turning
each N-Channel MOSFET “on/off” complementarily, produces an alternating current through the
transformer primary and secondary. The “on” duration of the switches determines the amount of
energy delivered to the CCFLs.
The current flowing through CCFL is sensed and regulated through sense resistor R502, R543.
The feedback voltage connected to Pin2 (ISEN), then compared with a interal reference
voltage ,resulting in PWM signal outputs to adjust output voltage.
Over Voltage Protection and over-current protection are monitored by the voltage on OV(Pin 1)
and LI (Pin2) During normal operation , if a CCFL is damaged or removed ,the voltage at OV
(Pin6) increases .Once the voltage at OV Pin exceeds 1.2V (OVPT Setting) the driver output
duty cycle is regulated and the shutdown delay timer is activated. Once over the delay time the
IC will shut down
