2.2 Alignment flow-chart
The alignment flow-chart is shown below (Fig. 1) :
Check if DDC, FLASH is written?
Make Data Process Board
Mounting alignment (Check if the voltage is 120V)
White balance alignment
Input test signal, check TV all performance (such as all programs are searched,
analog control, etc.). Check if headphone and speaker output normally.
Input HD signal, check if YPbPr jacks perform normally.
Input AV/SVIDEO signal, check if the AV jacks perform normally.
