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 userserviceable parts. This
monitor should only be repaired by a qualified technician.
-
Do not remove the monitor cabinet. There is highvoltage 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 nonammonia 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
When replacing parts or circuit boards, clamp the lead wires around terminals before
soldering.
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.
Keep wires away from high voltage, high temperature components and sharp edges.
Keep wires in their original position so as to reduce interference.
Usage of this product please refer to also user’s manual.

AIC1084-33PM (U202): DC power convert, used to 5v convert 3.3v.
RT9164-25PL (U201): DC power convert, used to 5v convert 2.5v.
W78E065A40PL (U601):
The W78E65 is an 8-bit microcontroller which has an in-system programmable Flash EPROM for
firmware updating. The instruction set of the W78E65 is fully compatible with the standard 8052.
The W78E65 contains a 64K bytes of main ROM and a 4K bytes of auxiliary ROM which allows
the contents of the 64KB main ROM to be updated by the loader program located at the 4KB
auxiliary ROM; 256+1K bytes of on-chip RAM; four 8-bit bi-directional and bit-addressable I/O
ports; an additional 4-bit port P4; three 16-bit timer/counters; a serial port. These peripherals are
supported by a eight sources two-level interrupt capability. To facilitate programming and
verification, the ROM inside the W78E65 allows the program memory to be programmed and
read electronically. Once the code is confirmed, the user can protect the code for security.
The W78E65 microcontroller has two power reduction modes, idle mode and power-down mode,
both of which are software selectable. The idle mode turns off the processor clock but allows for
continued peripheral operation. The power-down mode stops the crystal oscillator for minimum
power consumption. The external clock can be stopped at any time and in any state without
affecting the processor.

LD7552BPN (IC901): The LD7552B are low cost, low startup current, current
mode PWM controllers with green-mode power- saving operation. The integrated functions
include the leading-edge blanking of the current sensing, internal slope
compensation. They provide the users a superior AC/DC power application of higher efficiency,
low external component counts, and lower cost solution. Furthermore, LD7552B feature more
protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to eliminate the
external protection circuits. It is designed for the switching adaptor with 30W~60W output,
offered in both SOP-8 and DIP-8 package.

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: 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.
Boundary
Test Signal: 1280*1024@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.
White Balance
Test Signal: 640*480@60Hz
Test Pattern: White and Black Pattern
1.5.8 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.
Screen Uniformity and Flicker
Test Signal: 1280*1024@60Hz
Test Pattern: Full White Pattern
- Check and see if it is in normal condition.
1.5.10 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.
Mura
Test Pattern: White, RGB, Black, & Grey
Test Tool: 10% ND Filter
-
Check if the Mura can pass 10% ND Filter.
26
ViewSonic Corporation

VA502mb-1
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*350@70Hz; 640*480@60/67/72/75/85Hz;
720*400@70Hz; 800*600@56/60/72/75/85Hz;
832*624@75Hz, 1024*768@60/70/72/75/85Hz;
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 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.
