1)
Measure the DC voltage of pin 8. (VABL1)
2)
Set the subaddress (16) data to (1C).
3)
Applying external voltage to pin 8, lower the pin voltage from 6.5 V.
Measure the voltage of pin 8 when the voltage of pin 11 starts to change.
(VABL2)
4)
Change the data of subaddress (16) to (3C), (5C), (7C), (9C), (BC), (DC),
and (FC), and repeat step 3) for each of these data. (VABL3, VABL4,
VABL5, VABL6, VABL7, VABL8, VABL9)
5)
ABLP1 = VABL2 VABL1, ABLP5 = VABL6 VABL1

1)
Apply 6.5 V from an external power supply to pin 8.
2)
Set the subaddress (16) data to (00). Set the brightness to the maximum.
3)
Measure the voltage of pin 11. (VABL10)
4)
Apply 4.5 V from an external power supply to pin 8.
5)
Change the data of subaddress (16) to (00), (04), (08), (0C), (10), (14),
(18), and (1C), and repeat step 3) for each of these data.(VABL11,
VABL12, VABL13, VABL14, VABL15, VABL16, VABL17, VABL18)

1)
Adjust the brightness so that the picture period voltage of pin 11 is set to
2.5 V.
2)
Set the subaddress (16) data to (01).
3)
Measure the picture period voltages of pins 11, 13, and 15.
(V43R, V42R, V41R)
4)
Change the subaddress (16) data to (02) and repeat step 3).
(V43G, V42G, V41G)
