Are the RGB signals
outputted from
pin (9), (7), (4) of IC3104?
gradation signals?
NO
Are their RIN2-RIN9,
GIN2-GIN9, BIN2-BIN9
signals inputted into
IC2601 ?
YES
Are their signals inputted
into pins(51)-(55) (58)-(62)
of IC1101, IC1102,IC1201,
IC1202, IC1301, IC1302?
NO
Are their signals inputted
into pins (3)-(14) of
SC1101, SC1201 and
SC1301?
YES
Are the signals inputted
into the pins (1) of
SC1101, SC1201 and
SC1301?
NO
