Circuit Description
GC150AT/ATA
1. Audio circuit (Circuit diagrams Main PWB)
1.1 Audio input
The audio signal input received from the audio input terminal (JK011) is applied to the amplifier I001 of 4 (L-
CH) and 9 (R-CH) through the low-pass filter consisting of R040, R041, R042, R043, C040 and C041.
In this amplifier, controls of Volume and mute are conducted. The audio signal controlled at the pin 6 determines the attenuation of output of the amplifiers. Since then, the signal is output to the jack P003.
1.2 Audio output
The audio signal is output from the jack output terminal (P003) of the Audio board to the internal speaker system.
2. Power supply (Circuit daigrams MAIN PWB)
2.1 Line filter consists of C801, T801, C802, C803, C804. It eliminates high frequency interference to meet EMIs requirement.
2.2 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.
2.3 Power transformer :
T802 converts energy for square wave from power source C805 to secondary side to generate +12V and +5V.
2.4 Output :
The square wave from T802 is rectified by D809, D810, then filtered by C817, C822 to generate +12V and
+5V respectively.
2.4.1 A 5V power supply for LCD module, CPU and logic is generated from the power source.
2.4.2 I310 : 3-terminal regulator
A 3.3V power supply for I306 analog is generated from the 5V source.
2.4.3 I310 : 3-terminal regulator
A 3.3V power supply for I306 digital is generated from the 5V source.
Q303, Q304 ON/OFF control for LCD Module
ON/OFF control is performed for power ON/OFF and also for the power saving sequence.
2.5 Driver :
Q803 drive T802 from PWM control of I801 for power converted.
2.6 FB :
Negative feedback CKT consists of photo coupler I802 and adjustable regulator I803. It can maintain output voltages +5V and +12V at a stable level.
2.7 PWM :
2.7.1 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 pulse train through pin 6 to drive Q803.
2.7.2 OPP : When Q803 turns on, C805 supplies a linearly increasing triangle current through the primary induc tance of T802 to the driver Q803, once the peak value of this current multiplied by R811 exceeds1 volt, pulse
train will be shut down immediately to protect Q803, T802 from being burned out.
2.7.3 Regulation : If output voltage +5V goes up, the R terminal of I803 gets more bias, accordingly photo transis tor and photo diode flows more current. The voltage of pin 2 goes up too, making the pulse width of pin 6 to become narrower. So the output voltage +5V will be pulled down to a stable value.
Circuit Description Page 1
GC150AT/ATA
2.7.4 OVP : If +5V 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 at pin 6 goes down to zero, shutting Q803 off immediately.
2.7.5 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.

5. Definition converter LSI peripheral circuit (Circuit diagram MAIN PWB)
I306 gmZAN1 is the definition converter LSI.
The analog R, G, B signal input entered from the video input circuit is converted into the digital data of video signal through the incorporated A/D converter. Based on this conversion, this device performs interpolation during pixel extension. The source voltage for this device is 3.3V and the system clock frequency is 20MHz.
The withstand voltage level for the input signal voltage is 3.3V and 5V.
6. System reset, LED control circuit (Circuit diagram MAIN PWB)

9. CPU circuit (Circuit diagram MAIN PWB)
I302 (MTV312M64) functions as the CPU.
The source voltage for the device is 5.0V and the system clock frequency is 20MHz.
9.1 Detection of POWER switch status
The CPU identifies the ON status of the two power supplies. The identification is made when the power supply is turned off. For example, if the power supply is turned off with the POWER switch, the POWER switch must be turned on when activating the power supply again. If the power supply is turned off by pulling out the power cord, then this power supply can be turned on by connecting the power cord, without pressing the POWER switch.
9.2 Display mode identification
9.2.1 Functions
(1) Display mode identification l
The display mode of input signal is identified based on Table 1, and according to the frequency and polarity
(HPOL, VPOL) of horizontal or vertical sync signal, presence of the horizontal or vertical sync signal, and the discrimination signal (HSYNC_DETECT, VSYNC_DETECT).
l
When the mode has been identified through the measurement of horizontal and vertical frequencies, the total number of lines is determined with a formula of Horizontal frequency / Vertical frequency = Total number of lines. Final identification can be made by examining the coincidence of the obtained figure with the number of lines for the mode identified from the frequency.
l
When the detected frequency if the sync signal has changed, the total number of lines should be counted even through it is rge identified frequency in the same mode. Then, it is necessary to examine whether the preset value for the vertical display position of Item 4-3 has exceeded the total number of lines. If exceeded, a maximum value should be set up, which does not exceed the vertical display position of Item 4-3.
(2) Out-of -range
This out-of-range mode is assumed when the frequency of the horizontal / vertical signal is as specified below.
l
Vertical frequency : Below 50Hz or above 85Hz l
Horizontal frequency : Below 24 KHz or above 75 KHz
(3) Power save mode
The power save mode is assumed when the horizontal / vertical signals are as specified below.
l
If there is no horizontal sync signal input.
l
If there is no vertical sync signal input.
l
If the horizontal sync signal is outside the measuring range of gmZAN1.
l
If the vertical sync signal is outside the measuring range of gmZAN1.

10. Inverter
This unit operates on an output voltage of 15V from power source.
10.1 Regulator: Q101 get a +5VDC for I102 power supply.
10.2 UVP: Q106 turns off when the Vin is under 14V. Then pin 3 of I102 is pulled low and inverter off immediately.
That is the under voltage protection.
10.3 Control IC: I102 (OZ960S)
10.3.1 Enable : When pin 3 of I102 is over 1.5V, I102 works. If it is under 1.5V, I102 turns off.
10.3.2 OSC: When I102 enabled, R108/C115 (pin 17/pin18 of I102) determine the operating frequency.
10.3.3 SST: C104 (pin 4 of I102) provides soft start function.
10.3.4 Ignition: R109 (pin 8 of I102) provides higher operating frequency for more striking voltage until regulation
of feedback of lamp current. C103 (pin 1 of I102) determine the striking time.
10.3.5 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.
10.3.6 Regulation: Pin 9/pin 10 of I102 provide regulation of the CCFL current from feedback. The non-inverting
reference (pin 10 of I102) is at 1.25V nominal.
10.3.7 Protection: Open-lamp protection in the ignition period is provided through both pin1 and pin 2 of I102.
Removal of the CCFL during normal operation will trigger Q104 to turns on and shuts off the inverter. This
is latch function.
10.3.8 Output drivers: The configuration prevents any shoot-through issue associated with bridge-type power
conversion applications. Adjusting the overlap conduction between I101 P-MOSFET and I103 N-MOSFET,
I101 N-MOSFET and I103 P-MOSFET, the CCFL current regulation is achieved.
10.4 Full-bridge swit ching/Transformer: I101/I103 /C123/C125/T101/T102 compose full-bridge swit ching to
convert DC into AC for driver the CCFL.
10.5 Detection: C124/C119/CR102 detect the output voltage and ensure a rated voltage by pin2 of I102. Q102/Q103
ensure not a open-lamp.
10.6 Feedback: CR101/R120/R121/D108 sense the lamp current for negative feedback and regulation. The divided
voltage on R121 will be at 1.25V.
