Introduction<Introduction>

1. Basic concept of how to determine the defective board1) Verification of voltages

Normally, when there is a power problem, shutdown occurs immediately.

So, to resolve a power problem, voltage checks are necessary before shutdown.

2) Check if the power comes up after disconnecting the board under suspicion.

If power comes up (*) after disconnecting a board, the board is defective.

(*) “Power comes up” equals “no shutdown”.

2. Troubleshooting Video and Audio problems

3. Examples of video problems

4. Adjustment after PCB exchange1) After exchanging the following boards, voltage adjustment is required.

P board, SC board, SS board => Please refer to the “Service Manual”.

Troubleshooting for Picture Problems

35

Diagnostic Method for Troubleshooting PDP Television<Introduction>

1. There are two kinds of picture problem1) Abnormal picture

2) No picture

2. Basic concept of determining the defective board1) Which area is the symptom displayed on the screen?

A. Part of the screen

B. All over the screen

3. Adjustment after PCB exchange1) After exchanging the following boards, voltage adjustment is required.

P board, SC board, SS board => Please refer to “Service Manual”.

36

<Purpose>Picture problem such as “Picture Noise and or Vertical Line” displayed all over the screen is mainly caused by a defective D or DG board. The “internal Test Pattern Generator” can help determine whether to replace the D or DG board. The test patterns are created by the D board. Follow the steps below to confirm the operation of the D or DG boards.

Diagnosis by Test Pattern When OSD is Available

<How to enter the Test Pattern>1. While pressing "VOLUME-" button of the TV set,

press "RECALL" button of the remote control threetimes within 2 seconds.

2. Push button "1" of the Remote Control several timesto select the "OPTION" setting.

3. Press the "OK" button of the Remote control for three seconds or more to display the test pattern.

4. To display a specific pattern, press the OK button.

<Purpose>Symptom such as “No picture, No OSD, Sound OK” is mainly caused by a defective DG or D board. The internal

pattern generator cannot be accessed due to the loss of OSD. This method makes it possible to determine whether the DG board or the D (SC,SS) is defective.

<Block Diagram and Explanation>1. This white pattern is generated by IC9900 on D board.2. When the unit is turned on after disconnecting connector D5, a white picture is provided to the panel drive circuit.

If the panel drive section of the unit is ok, a white picture is automatically displayed by the PDP.

Troubleshooting for Picture Trouble

Where isthe symptom

displayed? *Note :Panel gas leakage

Because of a very small crack in the panel, gas leakage will start.In this picture, gas leakage started at the left top corner.Finally, gas leakage will lead to the symptom “No picture with buzz noise”.
