(1) Short circuit pin 31 (Y IN), pin 33 (B-Y IN) and pin 34 (R-Y IN) in
AC coupling.
(2) Input 0.3 V synchronizing signal to pin 48 (Sync IN).
(3) Set bus data so that R, G, B cut off data are set at center value.
(4) Connect pin 21 (Digital Ys) and pin 22 (Analog Ys) to ground.
(5) While changing bus data on brightness from maximum to minimum,
measure video voltage of pin 13 (G OUT) to find maximum and
minimum voltages (max : Vbrmx, min : Vbrmn).
(6) With bus data on brightness set at center value, measure video
voltage of pin 13 (G OUT) (Vbcnt).
(7) On the conditon that bus data with which Vbrmx is obtained in
measurement of the above step 5 is Dbrmx and bus data with
which Vbrmn is obtained in measurement of the above step 5 is
Dbrmn, calculate sensitivity of brightness data (Vbrt).
Vbrt = (Vbrmxg Vbrmng) / (Dbrmxg Dbrmng)

(1) In the same manner as the Note T16, measure video voltage of pin
12 (B OUT) with bus data on brightness set at center value.
(2) Find maximum axes difference in the brightness center voltage.
(1) Set bus data so that contrast and Y sub contrast are maximum and
brightness is minimum.

(2) Input TG7 sine wave signal
whose frequency is 100 kHz
and amplitude in video period is
0.9 V to pin 31 (Y IN).
(3) Connect pin 21 (Digital Ys) and
pin 22 (Analog Ys) to ground.
(4) While turning on / off WPL with
bus, measure video amplitude
of pin 14 (R OUT) with WPL
being activated (Vwpl).
