Input SG2 (0.2Vp-p) to TP22 and
measure the output amplitude at
TP12.
Input SG2 (0.2Vp-p) to TP22 and
measure the output amplitude at
TP12.
Input SG2 (0.2Vp-p) to TP22 and
measure the inverted output
amplitude Vinv and the non-inverted
output amplitude Vninv at TP12.
Input SG2 (0.2Vp-p) to TP22 (TP23,
TP24), measure the non-inverted
output amplitude at TP8, TP10 and
TP12, and obtain the maximum and
minimum difference between these
values.
Set CONT = 26h, input SG2 (0.2Vp-p)
to TP22, and assume the non-inverted
output amplitude at TP8 and TP10
when SUB-CONT R, B = 40h, 00h
and 7Fh as V1, V2 and V3, respectively.
Set U-BRT = 1Ah and measure the
non-inverted level at TP8 and TP10
relative to the non-inverted black
level at TP12 when SUB-BRT R, B =
7Fh and 00h.
Measure the R, G, B, PSIG and
COM output voltages in power
saving mode.
Set U-BRT = 00h, measure the
non-inverted black limit level at TP12
when BLK-LIM = 00h and 3Fh, and
assume the difference from the
output DC voltage as V
respectively.
Ginv = 20 log (Vninv/Vinv)
Gsc1 = 20 log (V3/V1)
Gsc2 = 20 log (V2/V1)
