1. PRECAUTION AND NOTICES
1.1. SAFETY PRECAUTIONS
This monitor is manufactured and tested on a ground principle that a user's safety comes first.
However, improper use or installation may cause damage to the monitor as well as to the user.
Carefully go over the following WARNINGS before installing and keep this guide handy.
WARNINGS:
! This monitor should be operated only at the correct power sources indicated on the label on
the rear end of the monitor. If you're unsure of the power supply in your residence, consult
your local dealer or power company.

! Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth.
Apply non-ammonia based cleaner onto the cloth, not directly onto the glass screen.
! Keep the monitor away from magnetic objects, motors, TV sets, and transformer.
! Do not place heavy objects on the monitor or power cord.
1.2. 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 voltages, 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.
1.3. SERVICE NOTES
1. When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit
board, keep the resistor about 5mm away from circuit board.
3. Keep wires away from high voltage, high temperature components and sharp edges.
4. Keep wires in their original position so as to reduce interference.
5. Usage of this product please refer to also user's manual.

7. WORKING THEOREM
A. DC-DC CONVERTER
This block provides adjustable output voltages of 9.2V, -6V, 18V and 3 to 4V for the panel.
It consists of a Q114 transistor and power switch IC I108 (AIC 1526-1).
When DC_ EN signal is high, then Q114 is activated and send one signal to activate I108.
At this time I108 will send 200KHz 12V PWM to Q106, Which is connected with L111, Q106,
D203 and C308, to boost 5V to 9.2V. And I108 offers the adjustable voltage of 3V to 4V. By
sending out pulses from pin 2 and pin 16 of I108 to double voltage circuit consisting of C301,
D201, D202 and C303, leaner regulator with Q105, would output –6V, 18V output id created,
according to the rule of –6V creation.
B. Scalaring controller
MascotV scalar is a highly integrated solution that combines a high performance ADC with an
advanced image processing controller. Using advanced image scaling algorithms, Mascot V has
intelligently adaptive sub-algorithms that will automatically optimize the display quality for
different images – the text is sharper and the graphics is smoother. The built-in analog interface
includes a 160Mhz, 8-bit 3-channel ADC, preamplifier, and VGA, allowing seamless support to
resolutions from VGA to XGA. MascotV also offers other integrated functions such as an internal
OSD that supports all languages, and build-in line buffers that allows support to a wide range of
LCD panels.
The scalar implements four advanced display technologies:
1. Sampling RGB input signals by fully integrated triple-channel ADC, PLL, and pre-amplifier
2. Automatically calibrate for vertical and horizontal alignment to center display and phase
calibration
3. High-quality advanced scaling: Enhanced and adaptive scaling algorithm for optimal image
quality
4. One and two pixels per clock panel support: Up to 24 bits per pixel.
The panel interface consists of 48-bit panel data bus, Start Pulse(STH1) and Clock (CLKH),
Polarity(POL)/Latch pulse(LP) for source driver IC, Start pulse(STV1) and Clock(CLKV) for gate
driver IC, and Data inversion control(HMSO/HMSE) for odd/even pixel bus and the power supply
(+3.2V, +3.45V<adjustable>,+9.2V, +18Vand-6V) for panel driver IC use.
C. Inverter
In order to drive the CCFLs embedded in the panel module, there is a ROYER inverter to convert
to convert
The input 12V up to hundreds of AC voltage output.
The inverter is formed by symmetric, in order to drive the separate lamp modules.
The input stage consists of a PWM controller, buck choke, and switching MOSFET to convert DC
input into AC output.
The output stage consists of a tuning capacitor, transformer, push-pull transistor pair to boost ac
output up to hundreds of voltage.
And one resister is serial to lamp for output cuttent feedback.
A 5-pin connector is the only interface to control the inverter. Pin 1 is 12V input, Pin 2/4 is the
returns, pin3 is the control of output current, and pin 5 is the enable/disable control.
