Using EEPROM adjustment mode, set CMP
CONTRAST
on 30 and
decrease value one by one. Decrease value by one when "L" starts to appear on output while displaying GO1 image.
Check that "H" always appears on each output while displaying image.
Using EEPROM adjustment mode, check that CONTRAST
is being 168 to make
adjustment. When OSD is displayed on EEPROM adjustment mode, ignore "L" output shown among lettered part.
