WARNING
This service information is designed for experienced repair technicians,
do not attempt to do any form of disassembling or adjustment for the
product.
It does not contain warnings or cautions to advise non-technical individuals of
the potential dangers in attempting to service the product.
Products powered by electricity should be serviced or repaired only by
experienced professional technicians.
Any attempts to service or repair the inner products may cause serious injury.
SAFETY PRECAUTIONS
Warning: This device must be operated with the original power supply
CAUTION: Use a power cable that is properly grounded. Always use the
appropriate AC cord that is certified for the individual
country. Some examples are listed below:

IMPORTANT NOTICE CONCERNING POWER CORD SELECTION
The power cord set for this unit has been enclosed and has been selected
according to the country of destination and must be used to prevent electric
shock. Use the following guidelines if it is necessary to replace the original
cord set, or if the cord set is not enclosed. The female receptacle of the cord
set must meet IEC-60320 requirements and will look like (Figure A1 below):
For the United States and Canada
In the United States and Canada the male plug is a NEMA5-15 style (Figure
A2), UL Listed, and CSA Labeled. For units which are mounted on a desk or
table, type SVT or SJT cord sets may be used. For units which sit on the floor,
only SJT type cord sets may be used. The cord set must be selected
according to the current rating for your unit. Please consult the table below for
the selection criteria for power cords used in the United States and Canada.

AC PLUG CORD PRECAUTIONS FOR THE UNITED KINGDOM
For your safety please read the following text carefully.
If the fitted moulded plug is unsuitable for the socket outlet then the plug
should be cut off and safely disposed. There is a danger of serving, electronically
shock, if the cut off plug is inserted into and appropriate socket.
If a new plug is to be fitted, please observe the wiring code as shown below. If
in any doubt, please consult a qualified electrician.
WARNING: THIS APPLIANCE MUST BE CONNECTED TO EARTH GROUND.
IMPORTANT: The wires in this mains lead are colored in accordance with the
following code:
Green-and-Yellow: Earth
Blue: Neutral
Brown: Live
If the colored wires of the mains lead of this appliance do not correspond with
the colored markings identifying the terminals in your plug, proceed as
follows:
The wire which is colored GREEN-AND-YELLOW must be connected to the
terminal in the plug which is marked by the letter E or by the Earth symbol or
colored GREEN or GREEN-AND-YELLOW.
The wire which is colored BLUE must be connected to the terminal in the plug
which is marked with the letter N or colored BLACK. The wire which is colored

If you have any questions concerning which proper power cord to use, please
consult with the dealer from whom you have purchased the product.
PRECAUTION
For best viewing conditions sit at least 18" from the LCD Display.
AVOID TOUCHING THE SCREEN WITH YOUR FINGERS. Oils from
the skin are difficult to remove.
NEVER REMOVE THE REAR COVER. The LCD Display contains
high-voltage parts. You may suffer serious injury if you touch these parts.
Avoid exposing the LCD Display to direct sunlight or another heat source.
The ViewPanel should be facing away from direct sunlight to reduce glare.
Always handle your LCD Display with care when moving it.
Place your LCD Display in a well-ventilated area. Do not place anything
on the ViewPanel that prevents adequate dissipation of heat.
Ensure the area around the LCD Display is clean and free of moisture.
Do not place heavy objects on the LCD Display, video cable, or power
cord.
If smoke, abnormal noise, or strange odor is present, immediately
switch the LCD Display off and call your dealer or ViewSonic. It is dangerous
to continue using the LCD Display.

6.2 System Circuitry Description
BLOCK A.
In reference to the system block diagram of the monitor’s
circuitry shown on the previous page, the analog RGB inputs
are amplified and sent through an analog-to-digital converter (ADC)
to a digital signal processor (DSP) that generates digital RGB
signals for controlling LCA panel.
BLOCK B.
A second power supply converts a single 12V supply to the
various voltages needed to run the LCD panel and the inverter
driving the display’s backlights.
BLOCK C.
SYNC SIGNAL PROCESSOR. This processor determines the
polarity of the horizontal and vertical sync signals, generates a
fixed-polarity synchronized clock signal and provides data for
use by the microprocessor in selecting circuit control parameters
from EEPROM tables.
