SUGGGESTIONS

1. Static precautionDrive section circuit is C-MOS circuit, so to protect against static electricity, wear static-proof wrist band.

2. Cleaningwhen wiping panel, do not use liquid cleaner or other chemicals . Use a damp cloth for cleaning .

3. handlingColor PDP uses high voltage(Max.500V). Be aware of electronic shock when handling PDP Unit and dont touch drive circuit.and even driver circuits capacitor is turned off but charge still remains there, so to touch drive circuit, be sure to wait at least 1 minute.

4. Warning when connecting signal & Power Connector in operation

do not touch connector while Color PDP is operating.

5. PDP servicing and guaranteeGlass Panel and Drive Circuit section are linked and operating together.if you disassemble and assemble the product in your own hands , LGE is exempted from the guarantee of function, quality and etc.

6. Damage in still imageColor PDP uses fluorescent material. The quality of PDP fluorescence by nature becomes deteriorated if using it in the same condition of CRT.To prevent this symptom, input full-screen regularly or use screensaver software.

So do not display the still image for a long time.

7. Temperature & ventilationColor PDPs Glass Panel section and Drive circuit section emit the heat so the temperature shall be kept under 40.the temperature of glass panel section is pretty high because built-in drive circuit emits the heat.PDP is operating with high voltage therefore be sure to keep it away from conductive objects.

8. Warning when handling Modulebe aware that PDP shall not be touched by metal or hard objects and shocked by the heat or mechanical force.be careful when disassembling or handling.

be sure to wear glove for preventing injury when the glasss broken.

Color PDP is a display device consisting of Panel section & Drive section. Panel section is composed of electrode,

fluorescent substances ,dielectrics and gases, and drive section is a combination of electrical circuit section and

PCB section. We call this concrete as PDP Module Assy and the following shows warning.


4/47


Service warning

1. One DVM ( FLUKE 87 or similar type )

2. Digital Oscilloscope ( over 200MHZ )

Defect diagnosis tool

1. When inserting parts or PCB, fasten the lead line to terminal before soldering.

2. When inserting high- voltage resistance(metal oxide film resistance or metal film resistance), keep 10mm away from PCB

3. High-voltage or high-temperature parts shall be away from the lead line.

4. This chassis is insulation(cold) chassis but for safety, it is better to use insulation trance.

when servicing power board, be sure to use insulation trance.

5. While PDP Module is in operation, do not connect or remove lines.

With COF or panel defect, report it to LGE PDP module service department.

4. Regular vertical line with one or more Data COF IC

1) It is mainly caused by X B/D output terminal buffers output error. When two Data COF ICs have regular vertical lines, it means the data transferfrom Controller B/D to X B/D has an error.

2) Check the related X B/D connector.

3) Replace that X B/D or CTRL B/D

1) This problem is related to CONTROL B/D.

2) Replace CONTROL B/D

7. Vertical Data copy

1) It possibly happens when scan wave does not form properly.

2) Replace Y B/D

case

8. One or more vertical lines in the screen.

1) Irregular vertical line is not related to Controller B/D or X B/D.

2) It is mainly caused by the followings open(or short).

- Panel itself defect

- DATA COF FPC attached to panel is open or short.

- DATA COF attached to panel itself defect

casenot always like this.

There can be several lines in area.

It can be seen on the both side, right and left.

The area is sometimes over .

9. One or more horizontal lines in the screen.

1) Irregular vertical line is not related to Controller B/D or Y B/D.

2) It is mainly caused by the followings open(or short).

-Y FPC connector reinsertion

- Open because of Y DRV B/Ds connector dry joint Y DRV B/D replacement

- Panel itself defect

- Y FPC attached to panel itself is open or short

Not always like this.

There can be several horizontal lines

case

10. Input signal pattern is displayed but the whole brightness of the screen is dark.

1) It happens when Z B/D is not operating well.

2) Check whether Z B/Ds power connector is plugged .

3) Check whether the signal connector between Controller B/D & Z B/D is plugged.

4) Replace Z B/D or controller B/D.

11. In full white pattern, foreign color is displayed or in full black pattern, mis-discharge is

partially occurred.

1) Check the slope & waveform of Y B/D set up, set down.

2) Check the slope of Z B/Ds ramp waveform

3) Measure each B/Ds output waveform by over 200MHz oscilloscope and compare it to the below picture.

it is possible to control Y B/Ds setup slope by adjustinng VR2, setdown slope by VR1 and Z B/Ds ramp slope by VR1- Y B/D measurement point : B61 ( SUS_UP OUTPUT )

1) Check CTRL B/Ds input signal connector.

2) Replace CTRL B/D.

12. In full white pattern, the brightness is getting darker toward the center.

1) It happens with Z B/Ds ramp waveform

2) Check the connection between CTRL B/D and Z B/Ds signal cable.

3) Replace Z B/D.

No image or same symptom when power off or black pattern.1) Check CTRL B/Ds LED(D1~D4).

2) Check the power or signal cable inputting into CTRL B/D.

3) Check X B/D, Y B/D and Z B/Ds power connector.

4) Check the connector between CTRL B/D and X B/D, Y B/D, Z B/D respectively.

5) Measure each X, Y, Z B/Ds output waveform with over 200MHz oscilloscope and compare it to the below picture to detect the defect

and replace that.

What is ISM Mode?

If display the still image for a long time, module is damaged,

so to avoid this phenomenon the brightness starts declining after 5 minutes display,

and after 15 minutes, the brightness is decreased up to 20%.
