    6. Appendix...
  • Page 26 6. Appendix Diagnosis by Test Pattern (1) (except PX80 series) <Purpose> In case of PDP, the picture problem at all over the screen (Picture Noise, Full Vertical Line) is mainly caused by D or A board defective. This Test Pattern is able to diagnose D or A board. Because, D board had Test Pattern.
  • Page 27 6. Appendix Diagnosis by Test Pattern (2) (except PX80 series) <Purpose> 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 the Service Mode.
