1. Precautions and Safety Notices

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) Use only a high quality, safety approved AC/DC power cord.

(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.

(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.

(7) Do not touch the LCD panel surface with sharp or hard objects.

(8) Do not place heavy objects on the LCD display, video cable, or power cord.

(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.

(10) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas containing excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- 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. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.

(2) Be sure to turn off power supply when connecting or disconnecting input connector.

(3) Wipe off water drops immediately. Long contact with water may cause discoloration or spots.

1

ViewSonic Corporation Confidential - Do Not Copy VE920m-1_VE920mb-1

(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 ensure human earth when handling.

(7) Do not open or modify the Module Assembly.

(8) Do not press the reflector sheet at the back of the module in any direction.

(9) In the event that a Module must be put back into the packing container slot after it was taken out of 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 or tilt 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 or

bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration

that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module

may be damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local

ordinances or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module

should be supplied with power that complies with the requirements of Limited Power Source

(IEC60950 or UL1950), or an exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950

Correct methods : Incorrect Methods :
Only touch the metal-frame of the panel or the front cover of
the monitor.
Do not touch the surface of the polarizer .

Surface of the panel is pressed by fingers & this may cause
“ MURA “

Take out the monitor with cushion Take out the monitor by grasping the LCD panel.

That may cause “ MURA“.

Place the monitor on a clean & soft foam pad . Place the monitor on foreign objects .

That could scratch the surface of panel

OSD Lock short cuts function for the buttons

The OSD lock will be activated by pressing the front panel control buttons "(1), & (▲)" for 10 seconds. If the user
then tries to access the OSD by pressing any of the buttons "1", "▼", "▲", "2" a message will appear on the screen
for 3 seconds showing "OSD Locked". The OSD lock will be deactivated by pressing the front panel control
buttons "(1), & (▲)" again for 10 seconds.
Note1: When the OSD is locked will lock all functions, including “Volume” and “Mute”
Note 2: Status bar indicating OSD Lock or Unlock is in progress and when complete it will indicate “OSD
Locked”
Note 3: OSD Lock should not lock Power Button and Power Lock function
Power Lock short cuts function for the buttons
The power button lock will be activated by pressing the front panel control buttons "(1), & (▼)" for 10 seconds.
Locking the power button means that the user won't be able to turn off the LCD while the power button is locked.
If the user presses the power button while it is locked, a message will appear on the screen for 3 seconds showing
"Power Button Locked". It also means that with the power button locked, the LCD would automatically turn back
"On" when power is restored after a power failure. If the power button is not in the locked mode, then power
should return to it's previous state when power is restored after a power failure. The power button lock will be
deactivated by pressing the front panel control buttons "(1), & (▼)" again for 10 seconds.

Note 1: Status bar indicating Power Button lock or unlock is in progress and when complete it will indicate
“Power Button Locked”
Note 2: Power should only be lockable in the “On State”

Memory Recall Actions

Memory Recall action on the analog and digital mode as below

1. Set the factory defaults as shown in Section 4-8

2. Clean all the mode setting buffer

3. Execute Auto Image Adjust

Note: Memory Recall should have no effect for Language, Power Lock, User Color Settings or Input Priority

Resolution Notice Actions

1. Resolution Notice OSD should show on screen after changing to non-native mode for 30 sec

2. The OSD should disappear after 10 sec or by pushing button [1] or [2]
Resolution Notice function should be disabled when push button [2] under Resolution Notice OSD

0-Touch™ Function Actions

1. Execute Auto Image Adjust when new mode detected, and save the settings to buffer for further use

2. It should be reset by Memory Recall function
(Should not reset by power off, power unplug and others)
OSD Auto Save
The OSD shall save new settings when it is turned off by the user or when it times out. There shall not be a

4. Circuit Description

The TSUM57AK is total solution graphics processing IC for LCD monitors with panel resolutions up to SXGA. It is
configured with a high-speed integrated triple-ADC/PLL, a high quality display processing engine, and an integrated output
display interface that can support RSDS panel interface format. To further reduce system costs, the TSUM57AK also
integrates intelligent power management control capability for green-mode requirements and spread- spectrum support for
EMI management.

The TSUM57AK incorporates the world’s first coherent oversampled RGB graphics ADC in a monitor controller system. The
oversampling ADC samples the input RGB signals at a frequency that is much higher than the signal source pixel rate. This
can preserve details in the video signal that ordinarily would be lost due to input signal jitter or bandwidth limitations in
non-oversampled systems. The TSUM57AK also incorporates a new Dynamic Frame Rate (DFR) generator for the digital
output video to the display panel that preserves the advantages of a fixed output clock rate, while eliminating the output end of
frame short-line.

5. Adjustment Procedure

A. Function Test and Alignment Procedure

1. All Modes Reset
You should do “All Model Reset” (Refer to Chap 3. Hot Keys for Function Controls) first. This action will allow
you to erase all end-user’s settings and restore the factory defaults.

2. Auto Image Adjust
The Auto Adjust is aimed to offer a best screen quality by built-in ASIC. For optimum screen quality, the user
has to adjust each function manually.

A.Turn the computer and LCD monitor on.
B. Press the ‘Auto’ button on monitor keypad to Auto Adjust.
C. The LCD monitor will start the Auto Adjust process automatically and run for 10 consecutive seconds, during

which time you will notice the image change.

3. Firmware
