1. PRECAUTION AND SAFETY 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.
Do not try to repair the monitor your self as it contains no user-serviceable parts. This
monitor should only be repaired by a qualified technician.
Do not remove the monitor cabinet. There is high-voltage parts inside that may cause
electric shock to human bodies, even when the power cord is unplugged.
Stop using the monitor if the cabinet is damaged. Have it checked by a service technician.
Put your monitor only in a clean, dry environment. If it gets wet, unplug the power cable
immediately and consult your service technician.
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.

4. Circuit Description
DC-DC CONVERTER
A.
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 sends 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, linear regulator with Q105, would output –6V, 18V output is created,
according to the rule of –6V creation.
Scalaring controller
B.
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 are 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 built-in line buffers that allow support for 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.
Inverter
C.
In order to drive the CCFLs embedded in the panel module, there is a ROYER inverter to
convert the input 12Vdc up to more than 600Vac.
The inverter is formed by symmetric outputs, 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 and one
resister is serial to lamp for output cuttent feedback.
A 5-pin connector is the only interface to control
returns, pin3 is the control of output current, and pin 5 is the enable/disable control.
