2-1

Precaution of assembly

（1）Please do not press or scratch PDP panel surface with anything hard. （2）Please wipe out PDP panel surface with absorbent cotton or soft cloth in case of it being soiled （3）Please wipe out drops of adhesive like saliva and water in PDP panel surface immediately. They might

mage to cause panel surface variation and color change

（4）Do not apply any strong mechanical shock to the PDP panel

2-2

Precaution of Operation：：

（1）Please be sure to unplug the power cord before remove the back-cover. (make sure the power is turn-off) （2）Please do not change variable resistance settings in PDP MODULE; They are adjusted to the most

suitable value. If they are changed, it might happen LUMINANCE does not satisfy.

（3）Please consider that PDP MODULE takes longer time to become stable of radiation characteristic in

mperature than in room temperature.

5、White-Balance Adjustment 5-1 Equipments list

Chroma7100 1set VG828 video signal generator 1set Chroma-2326 1set

5-2 Preparation and Adjustment process

1、Preparation:

 Connect rear Video port of PDP with AV port of VG-828.  Connect component port of PDP with YPbPr port of VG-828  Connect VGA port of PDP with corresponding port of Chrom2326  Turn power of PDP and test instrument on.  Before open lens, Press O-CAL of Chrom-7100 and revise lens.

2、Adjustment process

AV Adjustment

1). Change to Video mode, you can press “SOURCE” of remote. Press “Vol - ”, adjust volume until Min. Then press number key “6543”and enter factory Menu.

2). Press “SOURCE” and change to Video Rear mode

3). When setting of VG-828 is TIM946/PAT922, 32 Gray steps. Then, see the color of picture is deflection or not. And the Gray steps distinguish 28 steps from 32steps or not.

①. If dark of Gray is deflection, press “CH+/-”and adjust:

1.White.BRoCVBS (vMin=0,vMax=100,vDef=50) →50,

2.White.BBoCVBS (vMin=0,vMax=100,vDef=50) →50,

3.White.BGoCVBS (vMin=0,vMax=100,vDef=50) →50,

②. If sharpness of Gray is deflection, press “CH+/-”and adjust:

4.White.BRgCVBS (vMin=0,vMax=100,vDef=50) →50,

5.White.BBgCVBS (vMin=0,vMax=100,vDef=50) →50,

4). When the Gray is ok, change input signal to white picture at P936, Use colored analysis instrument Chroma7100 measure colors temperature value of picture at present (whether Chroma7100 is it given to picture center to pop one's head), On pressing the remote controller such as the specification of going beyond "program + /- "key choose following the projects adjust：

4.White.BRgCVBS (vMin=0,vMax=100,vDef=50) →50,

5.White.BBgCVBS (vMin=0,vMax=100,vDef=50) →50,

5). When adjustment about white is ok, changes signal to P822 that Gray steps picture. The Gray picture has no deflection color, and the Gray steps distinguish 28 steps from 32steps

Note: The white balance is adjusted in the course, will influence each other to adjust in the adjustment of gray steps and white picture, and need to change repeatedly. Please notice that can't enter the mode of the factory in every station homework after adjusting and finishing, so as not to miss movements and revise the white balance data again.

VGA Adjustment

Setting of Chroma2326 as follows:

Gray picture: TIM4/PAT48 White picture: TIM4/PAT105

Change to VGA mode, press “CH+/-”and adjust following items. Method same as AV mode:

6. White.BRoVga (vMin=0,vMax=100,vDef=50) →50,

7. White.BBoVga (vMin=0,vMax=100,vDef=50) →50,

8. White.BGoVga (vMin=0,vMax=100,vDef=50) →50,

9. White.BRgVga (vMin=0,vMax=100,vDef=50) →50,

10. White.BBgVga (vMin=0,vMax=100,vDef=50) →50,

Note: Press “Source” and change mode that Video Rear to VGA, then adjustment items of white balance same as Video Rear First, press “CH+/-” and adjust under the VGA mode. (White.BBgCVBS(vMin=0,vMax=100,vDef=50)→50 CVBS change to VGA）

COMPONENT Adjustment:

1). VG828 setting as follow：

Gray picture：TIM954/PAT922 White picture：TIM954/PAT936

2). Change to COMPONENT1 mode，press “CH+/-”and adjust following items. Method same as AV mode：

1. White.BRoVga (vMin=0,vMax=100,vDef=50) →50,

2. White.BBoVga (vMin=0,vMax=100,vDef=50) →50,

3. White.BGoVga (vMin=0,vMax=100,vDef=50) →50,

4. White.BRgVga (vMin=0,vMax=100,vDef=50) →50,

5. White.BBgVga (vMin=0,vMax=100,vDef=50) →50,

Adjustment stand of white Balance： x=299±15，y=315±15

6、DDC program and test 6-1 Equipments list and prepare DDC tester 1PCS

PC 1set D-SUB cable 1PCS DVI cable 1PCS Barcode reader 1set

Prepare before test:

1. Turn on the power of your PC and programmer, then make good connection of them.

2. Connect the D-SUB wire and DVI wire to the DDC program equipment and the PDP monitor.

6-2 Program and test process

1. Choose different DDC menu according to different customer , do use PAGE DOWN/PAGE UP to go to the submenu and parent menu until find the right model. Press enter to access the program interface. There will be shown RGB on the screen. Then switch to RGB program on the DDC connector。Press any key to access RGB program interface ,then there will be “input serial no.:” prompt on the screen.

2. Use Bar Readers to read the serial no to the program，then make sure the serial no you have read is the same as

on the barcode. Then set the PDP to blue screen mode, press enter to start.

3. Watch the information of the program, it means programmed OK when the following interface come out.

please CHECK Manufacturer Name、V endor Assigned Code、Model Name、Serial Number： ****[?????????****](same as Barcode)、Week of Manufacture：**、Year of Manufacture：****、Checksum： **（same as the last byte of data table, reference to the note of RGB programming picture）and so on.

4. Press Enter to access RGB DDC test interface，follow the DDC test picture，CHECK Manufacturer Name、

5. Press any key to access DVI program interface, there will be “DVI” shown on the screen. Switch the of

switch on the DDC connector, press any key to access DVI program interface, there will be “input serial no.:” promote.

6. Use Bar Readers to read the serial no to the program，then make sure the serial no you have read is the same

as on the barcode. Then set the PDP to blue screen mode, press enter to start.

7. Watch the information of the program, it means programmed OK when the following interface come out.

8. Press Enter to access DVI DDC test interface，follow the DDC test picture，CHECK Manufacturer Name、

V endor A ssigned Code、Model Name、Serial Number：****[?????????****](same as Barcode)、Week of Manufacture：**、Year of Manufacture ****、Video Input：Analog、Checksum：**（same as the last byte of data table, reference to the note of DVI programming picture）and so on。If the recording is failure, check the connection of equipment and record again from the step4.If all of these work does not take work ,please ask IE department for help.

9. Notice :the “?” and “*” symbol will be changed according to the year of manufacture ,and so on.
