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 D or DG (A) board defective. This Test Pattern is able to diagnose D or DG (A) board. Because, D board had Test
Pattern. So, we can judge by using Test Pattern which is defective. Regarding diagnosis for these board,
