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 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 Methods Correct Methods: Incorrect Methods:

1.Take out the monitor with cushions 1.Taking out the monitor by grasping the LCD panel. That may cause ”Mura”

2.Only touch the metal frame of the LCD panel

or the front cover of the monitor. Do not touch the surface of the polarizer.

2.Surface of the LCD panel is pressed by fingers and that may cause ”Mura”.

3.Place the monitor on a clean and soft foam

pad. 3.Placing the monitor on foreign objects. That

could scratch the surface of the panel or cause “Mura”.

4. Circuit Description 1. Power supply (DC/DC Converter)

This brick convert is the 110-220AC input voltage to 12V AND 5V output for inverter, audio, panel and system controller use.

It consists of a PWM IC (CM0565R, U101)

2. Scaling controller The ADC is to convert RGB analog signal to digital signal that scaling chip can

acknowledge. The HSYNC input receives a logic signal and provides the frequency reference for

pixel clock generation. The scaling IC is to converts the input signal ranging from VGA to WXGA into WXGA

resolution that panel can acknowledge.

GENERAL DESCRIPTION The TSUM17AK is a high performance, and fully integrated graphics processing IC solution

for LCD monitors with resolutions up to WXGA. It is configured with an integrated triple-ADC/PLL, a high quality scaling engine, an on-screen display controller, a built-in output clock generator, and LVDS display interface. To further reduce system costs, the TSUM17AK also integrates intelligent power management .

1.5 Function Test and Alignment Procedure

1.5.1 Memory Recall You should do “Memory Recall” first. This action will allow you to erase all

end-user’s settings and restore the factory defaults.

1.5.2 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.

1.5.3 Firmware Test Pattern: Burn In Mode (Refer to Chapter 3-1. Hot Keys for Function Controls) - Make sure the F/W is the latest version.

1.5.4 DDC Test Pattern: EDID program - Make sure it can pass test program.

1.5.5 Fine Tune and Sharpness

Test Signal: 1440x900@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.

1.5.6 Boundary Test Signal: 1440x900@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.

1.5.7 White Balance Test Signal: 1440x900@60Hz Test Pattern: White and Black Pattern

1.5.8 R, G, B, Colors Contrast

Test Signal: 1440x900@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.

1.5.9 Screen Uniformity and Flicker Test Signal: 1440x900@60Hz Test Pattern: Full White Pattern - Check and see if it is in normal condition.

1.5.10 Dead Pixel and Line Test Signal: 1440x900@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.

1.5.11 Mura Test Pattern: White, RGB, Black, & Grey Test Tool: 8% ND Filter - Check if the Mura can pass 8% ND Filter.

1.5.12 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.

1.5.13 Check for Secondary Display Modes

Test Signal: Analog / Digital:

640*350@70Hz 640*480@60HZ / 75HZ 720*400@70Hz 800*600@60HZ / 75HZ 832*624@75Hz 1024*768@60HZ / 75HZ1280*1024@60 / 75Hz

- Normally when the primary mode 1440x900@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.

1.5.14 Memory Recall After final QC step, we have to erase all saved changes again and restore the

factory defaults. You should do “Memory Recall” again.

1.5.15 Power Off Monitor Turn off the monitor by pressing “Power” button.
