1) Circuit Description
1. Power Board Operation1.1 Line filter consists of C801, T801, C802, C803, C804. It eliminates high frequency interference to meet EMI’s
requirement.1.2 Rec & Filter
Bridge diode D801 converts AC source into pulsed DC. This pulsed DC is smoothed and filtered by C805.R802 is an NTC ( negative thermal coefficient ) resistor, used to reduce inrush current to be within safe range.
1.3 Power transformer :T802 converts energy for square wave from power source C805 to secondary side to generate +12V and +22V.
1.4 Output :The square wave from T802 is rectified by D809, D811, then filtered by C822, C817 to generate +12V and +22Vrespectively. I804 is the regulator for +5V output.
1.5 Driver :Q803 drive T802 from PWM control of I801 for power converted.
1.6 FB :Negative feedback CKT consists of photo coupler I802 and adjustable regulator I803. It can maintain outputvoltages +22V and +12V at a stable level.
1.7 PWM :1.7.1 Start : When power is turned on, Q801 conducts due to bias from C805 and R805,R803. C807 is charged a
16 volt and a starting current about 0.3mA to pin 7 of I801. I801 starts to oscillate and outputs a pulsetrain through pin 6 to drive Q803.
1.7.2 OPP : When Q803 turns on, C805 supplies a linearly increasing triangle current through the primaryinductance of T802 to the driver Q803, once the peak value of this current multiplied by R811 exceeds1volt, pulse train will be turn off immediately to protect Q803, T802 from being burned out.
1.7.3 Regulation : If output voltage +22V or 12V goes up, the R terminal of I803 gets more bias, accordinglyphoto transistor and photo diode flows more current. The voltage of pin 2 of I801 goes up too, makingthe pulse width of pin 6 of I801 to become narrower. So the output voltage +5V will be pulled down to astable value.
1.7.4 OVP : If +22V or 12V goes up too much, the induced voltage on pin 4 of T802 becomes large also.Suppose that it is over 18 volts, ZD801 conducts, pin 3 of I801 is pulled up over 1 volt. The pulse train atpin 6 of I801 goes down to zero, shutting Q803 off immediately.
1.7.5 SCP : If output terminal is short to ground, photo transistor does not conduct, hence Q806 does not
conduct either. Then oscillation of I801 is stop, shutting Q803 off immediately.

2. Inverter OperationThis unit operates on an output voltage of 22V from power source.
2.1 VCC: When On/Off pin of P802 is high level input, Q106 turns on and provides +5VDC for I101 power supply.2.2 Control IC: I101 (OZ960S)
2.2.1 Enable : When pin 3 of I101 is over 1.5V, I101 works. If it is under 1.5V, I101 turns off.2.2.2 OSC: When I101 enabled, R108/C115 (pin 17/pin18 of I101) determine the operating frequency.2.2.3 SST: C104 (pin 4 of I101) provides soft start function.2.2.4 Ignition: R109 (pin 8 of I101) provides higher operating frequency for more striking voltage until regula-
tion of feedback of lamp current. C103 (pin 1 of I101) determine the striking time.2.2.5 Dimming control: The divided voltage of R106/R105/R104 control the duty pulse of burst-mode to drive
Q105 and perform a wide dimming control for the CCFL. The burst-mode frequency is determined by C116.2.2.6 Regulation: Pin 9/pin 10 of I101 provide regulation of the CCFL current from feedback. The non-inverting
reference (pin 10 of I101) is at 1.25V nominal.2.3 Protection: Open-lamp protection in the ignition period is provided through both pin1 and pin 2 of I101 to ensure
a rated voltage is achieved and a required timing is satisfied.Removal of the CCFL during normal operation will trigger the current amplifier (pin 9/pin 10 of I101) output andshuts off the inverter. This is latch function.
2.42.4.1 Output drivers: The configuration prevents any shoot-through issue associated with bridge-type power
conversion applications. Adjusting the overlap conduction between I102 P-MOSFET and I103 N-MOSFET,I101 N-MOSFET and I103 P-MOSFET, the CCFL current regulation is achieved.
2.4.2 Full-bridge switching/Transformer: I102/I103 /C123/T101 compose full-bridge switching to convert DCinto AC for driver the CCFL.
2.5 Detection: C128/C129/C132/D115/D114/C118 detect the output voltage and ensure a rated voltage by pin2 ofI101.
2.6 Feedback: D116/D117/R120/D108/R116 sense the lamp current for negative feedback and regulation. The dividedvoltage on R116 will be at 1.25V.

Final identification can be made by examining the coincidence of theobtained figure with the number of lines for the mode identified from the frequency. The DistinctionHsync and Vsync of each mode is shown in Table 3.
When the detected frequency if the sync signal has changed, the total number of lines should becounted even through it is range identified frequency in the same mode.
