<Caused Possibility>

A, D Board

<Diagnosis Procedure>

1. Disconnect A5 connector2. Enter to the Test pattern

<Counter Measure>

(*1)White Pattern and Test Pattern are generated by IC9300/IC9400 of D Board.When these patterns are normally displayed on the screen, It can be seemgood processing circuit between the D board and panel drive circuit.

Notice:Regarding information for test pattern in detail,Please refer to Page 26, 27.

Can you see theOSD on the screen?

After disconnect A5 connector then Power ON.Can you see the white pattern (*1)?

Enter to the test pattern. Can you see thepattern (*1) normally?

Notice:You can also diagnose which board is wrong by measuring waveform at TPSC1.Diagnosis procedure is as follows.


<Diagnosis Procedure>

<Block Diagram>

Disconnect SU board from SC board then Power ON. Can you see the picture normally at lower half?

In case of PDP, the picture problem at all over the screen (Picture Noise, Full Vertical Line) is mainly causedby D or A board defective. This Test Pattern is able to diagnose D or A board. Because, D board had TestPattern. So, we can judge by using Test Pattern which is defective. Regarding diagnosis for these board,please confirm as follows.

1. While pressing "VOLUME-" button of the TV set, press "INFO" button of the remote control three times within 2 seconds.2. Push button "1" of Remote Controller several times, and select "Aging" setting,then “Test pattern” will appear.3. Press "3" button for next picture in forward direction. (Press "4" button in reverse direction)

1. This white pattern is generated by IC9300,IC9400 on D board.2. When Power ON after removing A5 connector, white picture is provided to panel drive circuit. Then, white picture automatically appears in normal situation.

In case of No picture problem (Sound OK), the defective board is mainly A or D board. But in this case,Test Pattern isn’t useful for diagnosis. Because, this symptom can not display OSD and not enter to theService Mode. This method is possible to judge the defective board in this symptom.
