MEASUREMENT METHOD
D25
Gate Pulse V Mask Period
OFF
A
Input a composite video signal to TP38, observe the #34 (FBP in) waveform, and measure the V mask period.
D26
Sync Out Low Level
OFF
A
Input a composition video signal to TP38, observe the #36 (Sync out)
waveform, and measure the low level of the sync period.
D27
Vertical Oscillation Start
Voltage
OFF
B
Increase the voltage from 0 V. When a pulse is output from #33 (VD out), measure the voltage.
(Apply only DEF VCC.)
D28
Vertical Free-Run
Frequency
OFF
B
Measure the frequency of #33 (VD out).
D29
Vertical Output Voltage
OFF
B
1) Measure the high level voltage of the #33 (VD out) waveform. (VVH)
2) Measure the low level voltage of the #33 (VD out) waveform. (VVL)
D30
Service Mode Switching
OFF
B
When the subaddress (0C) D0 is set to (1), check that the #27 (V.Ramp) waveform is low (3.4 V DC).
D31
Vertical Pull-In Range
OFF
C
Input a composite video signal to TP38, vary the vertical frequency of this signal in 0.5-H steps, and measure the vertical pull-in range.
D32
Vertical Frequency
Forced 263H
Vertical Frequency
Forced 262.5H
OFF
B
1) Measure the number of H periods of #33 (HD out) when the subaddress (0D) D1 and D0 are set to (10). (fV1)
2) Measure the number of H periods of #33 (HD out) when the subaddress (0D) D1 and D0 are set to (11). (fV2)
D33
Vertical Blanking Off Mode
OFF
B
Set the subaddress (01) D7 to (1) and check that no vertical or horizontal blanking pulse is applied to #13 (R out), #14 (G out), or
#15 (B out).
