A
SCART2:
No picture from INPUT3 appears on INPUT2- connected monitor.
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" or "RGB".
2) The picture is sent to the monitor in a CVBS signal if the source during display is TV, CVBS or Y/C of INPUT1-3.
When sent by component, etc., that signal is not sent to the monitor.
3) When the monitor picture is not sent and is not displayed on the monitor, refer to "No picture" for each terminal.
4) The video output from INPUT1 is not the monitor output (output of the picture now watching).
The picture of the last selected TV channel is always sent to INPUT1. (Specification)
B
TERMINAL UNIT:
Is CVBS signal input from pin (51) of IC506 to pin (19) of
SCART2 (SC503)?
Is CVBS signal input from pin (5) of the connector P501 to pin (3)
of IC506 (VIDEO SELECTOR)?
MINI AV UNIT:
Is CVBS signal input from pin (6) of the input terminal J901 to pin
(5) of the connector (P501)?
C
Is V3_PLUG signal of the CVBS signal detection function from
pin (7) of the input terminal J901 normal?
Check between V3_PLUG_LINE J901 and pin (2) of IC506 in the
TERMINAL UNIT. (Connector P901/P501, etc.)
