Troubleshooting
No picture with S-
VIDEO input source
Check Computer source input stage;
Check RGB signals at test points TP-RIN/GIN/BIN.
Check IC4101, IC8201 and peripheral circuits.
Check sync signals at test points TPGHS and TPGVS.

SG: PC_RGB signals are selected in IC4101 and sent to IC8201. They are
A/D-converted in IC8201 and sent to IC301.
Sync: PC_H/V signals are sent to IC5301 and sync-separated in IC5301.
GHS and GVS signals are sent to IC8201 via IC5361.
Check AV source input stage;
Check Y/C signals at IC3101 and peripheral circuits.
Check sync signals AV_HSYNC and AV_VSYNC.
Yes
SG: S-video Y/C signals are converted to YCbCr signals in IC3101.
They are A/D-converted in IC8201 and sent to IC301.
The following route is the same as Component (480i/575i) signals.
Sync: AV_H/V_SYNC signals from IC3101 are sent to IC6301 and sync-sepa-
rated in IC6301. GHS and GVS signals are sent to IC8201 via IC5361.
Check AV source input stage;
Check RGB SCART signals at IC3101 and peripheral circuits.
Check sync signals AV_HSYNC and AV_VSYNC.
Yes
SG: RGB SCART signals are converted to YCbCr signals in IC3101 and sent
to IC4101. They are selected in IC4101 and sent to IC8201. They are
A/D-converted in IC8201 and sent to IC301.
The following route is the same as Component (480i/575i) signals.
Sync: SCART_CV signal at 13 pin of D-sub_15 is sent to IC3101.
AV_H/V_SYNC signals from IC3101 are sent to IC6301 and sync-sepa-
rated in IC6301. GHS and GVS signals are sent to IC8201 via IC5361.
Check AV source input stage;
Check IC2101, IC3101 and peripheral circuits.
Check sync signals AV_HSYNC and AV_VSYNC.
SG: Composite video signal is Y/C separated in IC2101 and sent to IC3101.
They are converted to YCbCr signals in IC3101.
The following route is the same as Component (480i/575i) signals.
Sync: Composite video signal is sent to IC3101. AV_H/V_SYNC signals from
IC3101 are sent to IC6301 and sync-separated in IC6301. GHS and GVS
signals are sent to IC8201 via IC5361.
