Checking the RGB signal
Are the RGB signals
outputted from
YES
pin (9), (7), (4) of IC3104?
gradation signals?
Check IC3104 and its
NOperipheral circuits.
Are their RIN2-RIN9, NO
GIN2-GIN9, BIN2-BIN9
signals inputted into
IC2601 ?Check IC8003 and its
peripheral circuits.
YES
Are their signals inputted
into pins(51)-(55) (58)-(62)
YES
of IC1101, IC1201,
IC1301?
Check IC2601 and its
NOperipheral circuits.
Are their signals inputted
into pins (5)-(10) of NO
SC1101, SC1301 and into
pins (23)-(28) of SC1201?
Check IC1101, IC1201,
YESIC1301, and their peripheral
circuits.
Are the signals inputted
into the pins (3) of
YES
SC1101, SC1301 and into
the pin(30) of SC1201?
Check IC1101, IC1201,
NOIC1301, and their
peripheral circuits.
Are the signals inputted NO
into the pins (31) of
SC1101, SC1201 and
SC1301?Check IC1103, and its
peripheral circuits.
YES
Check the connection
of LCD panels.
And when video signal and
OSD are also not
disaplaied, replace the
LCD panels .
