1. Precautions and Safety Notices
1. Please carefully read this manual before operating the device and keep it available for future reference.
2. To avoid the danger of the monitor falling and thereby possibly causing injury and/or serious damage to the
monitor itself, do not place it on unstable cars or desks. Be careful to avoid placing any stress on the LCD screen
during handling.
3. Do not place this monitor in areas that are wet or where water or other liquids may come in contact with it, such as
bathrooms, kitchens, wet floors, near washing machines or by swimming pools.
4. Remove the power plug from the electrical socket before cleaning. No water-containing cleaning agent should be
used to clean the screen, but only cleaning agents formulated specifically for cleaning LCD screens. Do not put any
liquid cleaning agent directly on the screen, but put it on a soft cloth first and then gently apply the cloth to the
screen.
5. In order to guarantee reliable operation and adequate heat dissipation, do not cover or block vent holes on the
monitor. Do not put the monitor close to heat sources. Do not place the monitor on furniture such as a bookshelf,
unless sufficient ventilation is available.
6. A 3-pin grounding plug is provided for this monitor. In order to guarantee normal operation and safety of this unit,
this plug should be used with a matching grounded power socket.
7. Please follow all warnings and instructions that accompany the monitor.
8. Please pay special attention to power supply overloads, as electrical shock or fire may occur.
9. Do not place anything on the power cord. Do not hang the power cord over an area where people or objects may
pass.
10. In case the monitor is not be used for an extended period, turn off power to avoid the possibility of short circuits
caused by lightning.
11. In order to avoid electrical shock or fire risks, do not insert any object through any openings in the monitor’s
enclosure. Do not allow any liquid to come in contact with the monitor.
12. In case of any abnormal noise or odor caused by incorrect operation, turn off power immediately and contact a
professional technician. Do not attempt to repair this monitor by yourself, as electrical shock may occur when
opening the back cover or accessing internal components.
13. If any of the following conditions occurs, turn off power and contact a repair service provider:
1) the power cord is damaged or worn;
2) liquid has gotten into the monitor, or the monitor has experienced immersion or wetting;
3) the monitor has fallen;
4) the monitor’s performance shows obvious changes;
5) the monitor fails to work normally when correct procedures are followed. In that case, please make any
adjustments in accordance with instructions supplied with the monitor; do not attempt any changes to
established procedures, as further damage may occur, making successful repair of the monitor more difficult.
14. In case parts need to be replaced, you must use identical parts or those supplied by our certified manufacturers. Any
other parts used without our authorization may result in electrical shock or fire risk.

4. Circuit Description
A. AC-DC CONVERTER
The power supply with a high-integrated green-mode PWM controller provides several features to
enhance the performance of power flyback converters.
U801 is a PWM controller and provides many protection functions.
U802 is a photo couple to transfer the feedback signal from the second side which U803 detected both of
the output DC voltage on 5V and 24V.
Z802 detected the working voltage on U801 and Q802 would pull down the voltage on U801 pin5 to
shut down U801 if feedback loop was failed.
R828 would be a dynamic load which was active while backlight was turned off and system still
working on, this kept 24V output voltage under 32V to protect the panel. After system went to
power saving mode, the R828 would no loaded. This was detected by Z803 active the R828 to load or
not.

D. INVERTER
In order to drive the CCFLs embedded in the panel module, there is a push-pull inverter to convert by the controller.
from input 24V up to hundreds of AC voltage output peak to peak.
The inverter is formed by symmetric in order to drive the separate lamp modules.
The input stage consists of a PWM controller, push-pull inverter, and switching MOSFET to convert DC input into
ViewSonic Corporation Confidential - Do Not Copy VA903b-1_ VA903m-1
22
AC output.
The output stage consists of a tuning capacitor, transformer, and push-pull MOSFET pair to boost AC output up to
hundreds of voltage peak to peak.
And one resister is serial to lamp for output voltage feedback.
There are two signals which control the inverter come from system to turn on the inverter and control brightness.
Logic “low” level which send to U901 is turn on the inverter.
BL-ADJ signal control brightness by DC level which was integral from PWM signal.

Firmware Update Procedure
1. The monitor’s firmware update for VA903m/b have two method.
Download the MCU IC by the fire machine. This procedure is finished in SMT.
ISP Method. When the monitor ’s BIOS isn’t exist or firmware isn’t final program, this method Is worked by ISP
Cord with monitor.
2. VA903m/b monitor upgrade firmware by ISP Cord.
Equipment Needed
- USB cable for print port *1
- VGA cable*1
- LPT cable (25pin)*1
- AC power cable*1
- ISP fire cord (the fixture is made in TE ) for firmware upgrade*1
- Power adapter for firmware upgrade (this adapter is made in TE)*1
- A computer with Windows XP
- VA903m/b monitor ( no firmware)
- a additional monitor for system display
- ISP & ISP3.0program
NOTE:
The fixtures for firmware upgrade provide two differen t methods to fire. Please check you monitor’s Main board,
refer to MCU-RSIC type and choose the method.
