Is Component Y/Pb/Pr signal sent to pin (2)/Y, (4)/Pb, (6)/Pr of
AV1(CN552) ?
NO
Check the setting of an external input device that connects of
CN552.
Refer to “The picture doesn't appear in all modes.”
Is Component Y/Pb/Pr signal sent to pin (AE21)/Y, (AD22)/Pb,
(AF22)/Pr of IC U400?
NO
Check the line between IC U400 and CN552.
Is CVBS signal output into pin (19) of CN500 (SCART1)?
YES
Check the setting of an external input device that connects of
CN500.
Refer to “The picture doesn't appear in all modes.”
Is TUNER_CVBS signal output into pin (21) of CN500 (SCART1)?
YES
Check the line between CN500 and TU200.
Checklist:
1) Is the Signal Type (item) in MENU-Option-Input Select equal to Signal Type of an external device? …Set it to “CVBS”, “Y/C”, “RGB”, “AUTO”.
2) Is ANT-CABLE disconnected or connected improperly? …Connect it correctly as per the operation manual.
3) The picture is sent to the monitor in a CVBS signal if the source during display is ATV/DTV, CVBS or Y/C of SCART1, AV3.
When sent by component, etc., that signal is not sent to the monitor.
4) When the monitor picture is not sent and is not displayed on the monitor, refer to “No picture” for each terminal.
5) The video output from SCART1 is not the monitor output (output of the picture now watching).
