Input 100-kHz sync signal to TP67, and set #67 amplitude to 0.2 Vp-p.
Set Y mute OFF (P-MODE: Normal 1, 000), brightness to center (1000000), color to center (1000000),
unicolor to maximum (1111111), and Y/C Gain Comp to minimum (00). Set black stretch point 1 to OFF (000),
dark area static Y γ gain to minimum (00), light area static Y γ gain to maximum (11), and SW1 to B. Apply 5.16
V to #68 from external power supply PS1.
Monitor #14 output waveform, and measure amplitude VBDY0.
Set Y/C Gain Comp to maximum (11). Set SW1 to B. Set black stretch point 1 to OFF (000), dark area static
Y γ gain to maximum (11), light area static Y γ gain to maximum (00), and monitor #14 amplitude VBDY1.
Set Y/C Gain Comp to maximum (11). Switch SW1 to A, and TPI to GND. Set black stretch point 1 to
maximum (111), dark area static Y γ gain to minimum (00), bright area static Y γ gain to maximum (11), and
monitor #14 amplitude VBDY2.
Calculate the following equations.
Input 100-kHz sync signal to TP5, and repeat the procedure above. Calculate the following equations.
