1. Precautions 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.

♦ Use only the special power adapter that comes with this monitor for power input.

♦ 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 technacian.

♦ 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.

— Adds blue to the screen image for cooler white (used

in most office settings with fluorescent lighting).

6500K

— Adds red to the screen image for warmer white and

richer red. Default setting.

5400K — Adds green to the screen image for a darker color.

Custom User Color

— Individual adjustments for red, green,

4. Circuit Description

4.1 Inverter Board Circuit

The diagram of inverter board circuit is shown in Appendix (PWB-0538). The inverter supplies power for

backlight for the LCD panel.

4.2 Power supply Board Circuit

Please refer to power Schematic sheet in Appendix. The 12Vdc from adaptor output is fed into J800 as

power regulation of U801 (AO4403) input power and inverter main power on pin 1 of CN830. The U801 can

provide two independent power sources: a) The 5Vdc will be for main board power. ; b) The another 10.5Vdc

will output as audio power at when audio jet is inserted.

4.3 Scaling controller Board Circuit

The Scaling IC U005 is to convert the input signal from VGA, SXGA and UXGA to a SXGA resolution that

panel can acknowledge.

The scaling IC of MRT MASCOT V2 is a highly integrated System-on-a- Chip with very powerful functions,

including integrated 8 bit triple-channel ADC/PLL, programmable OnPanel timing controller, embedded

microcontroller with parallel ROM interface, OSD engine, sRGB compliance, and PWM back light intensity

control.

The Scaling IC features an integrated timing controller (TCON) that connects directly to commercially

available row and column drivers. All TCON signals OCLK, ECK, ORGB, ERGB, OSP, ESP, OPOL, OINV,

EINV on pin 68 to pin 79 of U005 have programmable drive strengths and can be disabled to control Panel.

The flash memory chip of U001 contains codes via parallel data bus interface to communicate

with Scaling IC U005.

The DDC memory chip of U004 stores DDC data and the NVRAM chip stores timings and setting data.

Since the NVRAM has to get series number information data from DDC chip, both their SDA and SCL

ports connected together. In order to avoid conflict on I C interface during the DDC transfer from U004,

2

the electrical switching of U009 is isolated and controlled by scaling IC pin GPIO7.

4.4 Audio Circuit

The audio Right/Left channels are fed into pin 6 /8 of sound AMP U701 (AN7522) while Audio plug is

inserted on J701 jack. The sound output amplitude will depend on this bias voltage on pin 9 of U701, which

is always controlled by Q702. When mute is activated, the Q703 will be forced to saturation to block sound

output. When standby is activated, the sound outputs of U701 will drive speakers via CN701 connecter.
