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
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 you 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 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.

1.4 HANDING AND PLACING METHODS
Correct Methods: Incorrect Methods:
Only touch the metal frame of the LCD
panel or the front cover of the monitor. Do
not touch the surface of the polarizer.
Surface of the LCD panel is pressed by fingers
and that may cause “Mura.”
Take out the monitor with cushions
Place the monitor on a clean and soft foam
pad.
ViewSonic Corporation

Taking out the monitor by grasping the LCD
panel. That may cause “Mura.”
Placing the monitor on foreign objects. That
could scratch the surface of the panel or cause
“Mura.”

Do the following to adjust the display setting:
1. To display the Main Menu, press button [1].
NOTE: All OSD menus and adjustment screens disappear automatically after about 15
seconds. This is adjustable through the OSD timeout setting in the setup menu.
2. To select a control to adjust, press ▲or ▼ to scroll up or down in the Main Menu.
3. After the desired control is selected, press button [2]. A control screen like the one
shown below appears.

Auto Image Adjust automatically sizes, centers, and fine tunes the video
signal to eliminate waviness and distortion. Press the [ 2 ] button to obtain a
sharper image.
NOTE: Auto Image Adjust works with most common video cards. If this
function does not work on your LCD display, then lower the video refresh rate
to 60 Hz and set the resolution to its pre-set value.
Contrast adjusts the difference between the image background (black level)
and the foreground (white level).
Brightness adjusts background black level of the screen image.
Color Adjust provides several color adjustment modes, including preset color
temperatures and a User Color mode which allows independent adjustment of
red (R), green (G), and blue (B). The factory setting for this product is 6500K

will cause Contrast and Brightness adjustments to be disabled.
9300K-Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).

4.3 Function Test and Alignment Procedure
All Modes Reset
You should do “All Mode Reset” (Refer to Chapter III-3. Hot Keys for Function
Controls) first. This action will allow you to erase all end-user’s settings and restore
the factory defaults.
Auto Image Adjust
Please select and enter “Auto Image Adjust” function on Main Menu to see if it is
workable. The “Auto Image Adjust” function is aimed to offer a better screen quality
by built-in ASIC. For optimum screen quality, the user has to adjust each function
manually.
Firmware
Test Pattern: Burn In Mode (Refer to Chapter III-3. Hot Keys for Function Controls)
- Make sure the F/W is the latest version.
DDC
Test Pattern: EDID program
Make sure it can pass test program.
Fine Tune and Sharpness
Test Signal: 1440*900@60Hz
Test Pattern: Line Moire Pattern
Check and see if the image has noise and focus performs well. Eliminate visual
line bar.
If not, readjust by the following steps:
(a)Select and enter “Fine Tune” function on “Manual Image Adjust” to adjust the
image to eliminate visual wavy noise.
(b)Then, select and enter “Sharpness” function to adjust the clarity and focus of
the screen image.
Boundary
Test Signal: 1440*900@60Hz
Test Pattern: Horizontal & Vertical Line Thickness Pattern
Check and see if the image boundary is within the screen frame.
If not, readjust by the following steps:
(a)Select and enter “Manual Image Adjust” function on OSD Main Menu.
(b)Then, select and enter “Horizontal Size” or “Horizontal/Vertical Position” function
to adjust the video boundary to be full scanned and within screen frame.

Test Pattern: White and Black Pattern
1.5.8 R, G, B, Colors Contrast
Test Signal: 1440*900@60Hz
Test Pattern: R, G, B, Color Intensities Pattern and 16 Gray Scale Pattern
- Check and see if each color is normal and distinguishable.
- If not, please return the unit to repair area.
Screen Uniformity and Flicker
Test Signal: 1440*900@60Hz
Test Pattern: Full White Pattern
- Check and see if it is in normal condition.
1.5.10 Dead Pixel and Line
Test Signal: 1440*900@60Hz
Test Pattern: Dark and White Screen Pattern
- Check and see if there are dead pixels on LCD panel with shadow gauge and
filter film.
- The total numbers and distance of dead pixels should be compliant with the
spec.
Mura
Test Pattern: White, RGB, Black, & Grey
Test Tool: 10% ND Filter
- Check if the Mura can pass 10% ND Filter.
Audio
Test Signal: Voice signal (optional, depend on model)
Test Pattern: liberty
- Make sure there is audio output.
- Make sure that audio function (volume 80%) is working without noise and
resonance.
- Make sure that the sound of right and left speakers are in balance.
Check for Secondary Display Modes
Test Signal:
Analog: 640*480@60/75Hz;
720*400@70Hz; 800*600@56/60/72/75Hz;
1024*768@60/70/72/75Hz; 1280*1024@60/75Hz
1440*900@60/75Hz
- Normally when the primary mode 1440*900@60Hz is well adjusted and
compliant with the specification, the secondary display modes will also be
compliant with the spec. But we still have to check with the general test pattern to
make sure every secondary is compliant with the specification.
All Modes Reset
After final QC step, we have to erase all saved changes again and restore the
factory defaults. You should do “All Mode Reset” again.
Power Off Monitor
Turn off the monitor by pressing “Power” button.

D704(SSM12L) Vf=0.38V and If=1A.
So when system power on, the
system loading is about 400mA
(3.3V is about 200mA and 1.8V is
about 200mA), So D35 changed
from 1N4148(or BAT42) to
SSM12L(schottky diode).
P.S: The 1N4148 Vf=0.7V~1V can't meet
LDO spec. The BAT42, Vf is OK but the
If=200mA(forward current) can not
meet current spec.
