SG: PC_RGB signals are sent to IC8201. They are A/D-converted in IC8201
and sent to IC301.
Sync: PC_HS/VS signals are sent to IC8201 via IC8271(Inverter IC) and ADHS
and ADVS signals are sent to IC301.
Check AV source input stage;
Check Y/C signals at IC8201, IC5231 and peripheral circuit.
Check sync signals at test points TPADHS and TPADVS.
Yes
SG: Y signal is selected in IC5231, with S/CV_SW signal(S-VIDEO = Low).
The selected signal is sent to IC8201. S_CHROMA signal is sent to
IC8201. They are A/D-converted in IC8201 and sent to IC301.
Sync: Y/C signals are sync-separated in IC8201, and ADHS and ADVS signals
are sent to IC301.
Check Computer source input stage;
Check RGB SCART signals at test points TP-RIN/GIN/BIN.
Check IC8201, IC5231 and peripheral circuit.
Check sync signals at test points TPADHS and TPADVS.
Yes
SG: RGB SCART signals are A/D-converted in IC8201 and sent to IC301.
Sync: SCART_CV signal at 13 pin of D-sub_15 is selected in IC5231, with
S/CV_SW signal(SCART = High). The selected signal is sent to IC8201. It
is sync-separated in IC8201, and ADHS and ADVS signals are sent to
IC301.
Check AV source input stage;
Check IC8201 and peripheral circuit.
Check sync signals at test points TPADHS and TPADVS.
SG: Composite video signal is sent to IC8201, and sent to IC301.
Sync: Composite video signal is sync-separated in IC8201, and ADHS and
ADVS signals are sent to IC301.
