) to pin 3. Adjust DRIVE
GAIN 1/2 so that pin 41/42 picture period amplitude is equal to that of pin 43.
(2) Measure voltage of pins 46, 47 and 48 and apply measured voltages from external power
supply to pins.
(3) Set sub-address (02) data to 40.
(4) Determine ACB pulse phase by referencing signal waveform output from pins 43, 42 and 41
as shown in Figure 1 below.
Note: The first picture period after V-BLK ends and FBP input falls is 1H. After each H-BLK, the
phase is 2H, 3H and so on.
(5) Determine ACB pulse amplitudes VACB1R, VACB1G and VACB1B by referencing signal
waveform output from pins 43, 42 and 41. (Amplitude is based on picture period level at no
input.)
(6) Repeat step (5) above, setting sub-address (02) data to 80, and measure VACB2R, VACB2G
and VACB2B.
(7) Repeat step (5) above, setting sub-address (02) data to C0, and measure VACB3R,
VACB3G and VACB3B.
