1. Precautions and Safety Notices
1. Appropriate Operation
(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Disconnect the power plug from AC outlet if the product is not used for a long period of time.
(5) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(6) Do not touch the LCD panel surface with sharp or hard objects.
(7) Do not place heavy objects on the LCD display, video cable, or power cord.
(8) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(9) Do not operate the product under the following conditions:
- Extremely hot, cold or humid environment.
- Areas susceptible to excessive dust and dirt.
- Near any appliance generating a strong magnetic field.
- Place in direct sunlight.
2. Caution
No modification of any circuit should be attempted. Service work should only be
performed after you are thoroughly familiar with all of the following safety checks and servicing
guidelines.
3. Safety Check
Care should be taken while servicing this LCD display. Because of the high voltage used in the
inverter circuit, the voltage is exposed in such areas as the associated transformer circuits.
4. Power Supply Requirements
The external AC power operating range shall be from 90 to 264Vac
5. LCD Module Handling Precautions
5.1. Handling Precautions
(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when inserting or disconnecting from input connector.
(3) Wipe off water drop immediately. Long contact with water may cause discoloration or
spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard
surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and insure human
earth when handling.
(7) Do not open nor modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module to any directions.
(9)
In case if a Module has to be put back into the packing container slot after once it was
taken out from the container, do not press the center of the CCFL Reflector edge. Instead,
press at the far ends of the CFL Reflector edge softly. Otherwise the TFT Module may be
damaged.
(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt
1
ViewSonic Corporation Confidential - Do Not Copy VX2835wm-1
Page 5
the Interface Connector of the TFT Module.
(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for
example), do not twist nor bend the TFT Module even momentary. At designing the
enclosure, it should be taken into consideration that no bending/twisting forces are applied
to the TFT Module from outside. Otherwise the TFT Module may be damaged.
(12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow
local ordinances or regulations for disposal.
(13) Small amount of materials having no flammability grade is used in the LCD module. The
LCD module should be supplied by power complied with requirements of Limited Power
Source, or be applied exemption.
(14) The LCD module is designed so that the CFL in it is supplied by Limited Current Circuit
Do not connect the CFL in Hazardous Voltage Circuit.

5.2 handling and placing procedure
1. Open the carton box, before you remove anything from the carton box, check all the accessory
listed in the packing list.
Remember the position of the left and right poly foams to avoid any problem when packing them.
2. When removing the LCD monitor, make sure that you are holding from the back side of the LCD
monitor and not the front side of the LCD monitor.

5.3 Function Test and Alignment Procedure
5.3.1 All Modes Reset
You should do “All Mode Reset” first. This action will allow you to erase all end-user’s
settings and restore the factory defaults.
5.3.2 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.
5.3.3 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.
5.3.4 DDC
Test Pattern: EDID program
- Make sure it can pass test program.
5.3.5 Fine Tune and Sharpness
Test Signal: 1280*1024@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.
5.3.6 Boundary
Test Signal: 1280*1024@60Hz
Test Pattern: Horizontal & Vertical Line Thickness Pattern

ViewSonic Corporation Confidential - Do Not Copy VX2835wm-1
Page 48
5.3.8 R, G, B, Colors Contrast
Test Signal: 1280*1024@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.
5.3.9 Screen Uniformity and Flicker
Test Signal: 1280*1024@60Hz
Test Pattern: Full White Pattern
- Check and see if it is in normal condition.
5.3.10 Dead Pixel and Line
Test Signal: 1280*1024@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.
5.3.11 Mura
Test Pattern: White, RGB, Black, & Grey
Test Tool: 8% ND Filter
- Check if the Mura can pass 8% ND Filter.
5.3.12 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.
5.3.13 Check for Secondary Display Modes
Test Signal:
Analog: 640*350@70Hz; 640*480@60HZ
720*400@70Hz; 800*600@60HZ/70HZ/75HZ
832*624@75Hz, 1024*768@60HZ/70HZ/75HZ
1280*1024@60/75Hz
- Normally when the primary mode 1280*1024@60Hz is well adjusted and compliant
with the specification, the secondary display modes will be great possible to 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.
