6. Appendix Diagnosis by Test Pattern (1)
In case of PDP, the picture problem at all over the screen (Picture Noise, Full Vertical Line) is mainly caused
by A board or Panel defective. This Test Pattern is able to diagnose A board. Because, A board had Test
Pattern. 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 " 0 " 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 < Test Pattern (Abnormal)>
and test patterns are shown repeatedly. Example Picture
Press "4" button for previous picture in reverse direction
and test patterns are shown repeatedly.
(or Push "GREEN" button in forward direction and
test pattern are not shown repeatedly)
(or Press "RED" button in reverse direction and
test pattern are not shown repeatedly)
