Input signal 1 (f
Change unicolor data to maximum (7F), center (40), and minimum (00) and measure pin 12
picture period amplitude, V
Calculate amplitude ratio of V
Input signal 2 from pin 68 and adjust pin 12 picture period output amplitude to 1 Vp-p.
Change brightness data to maximum (7F), center (80), and minimum (00) and measure pin
12 voltages, V
Set subcontrast to maximum.
Apply external power supply to pin 68 and gradually increase voltage from 5.8 V.
When picture period of pin 12 is clipped, measure pin 12 picture period amplitude voltage,
V
Change subaddress (0C) data to (FC) and repeat the steps 1 to 3 above. (V
Apply external power supply to pin 68 and gradually decrease voltage from 5.8 V.
When picture periods are clipped, measure pins 14, 13, and 12 voltage, V
Adjust brightness data so that picture period voltage of pin 14 is 2.4 V.
Set color data to minimum.
Measure noise levels n14-, n13-, and n12-Vp-p in picture period of pin 14, 13, and 12 with an
oscilloscope.
Calculate S/N.
Input signal 1 (f
Measure pin 14 picture period amplitude v14A.
Apply 1.5 V to pin 79 from external power supply.
Measure pin 14 picture period amplitude v14B
Calculate the following equation. G
Stop applying voltage to pin 79. Set subaddress (1A) to data (E2) and measure pin 14-picture
period amplitude, v14C.
Calculate the following equation. G
