SCART1:
No picture appears on EXT1-connected 
monitor during the tuner reception.

SCART2:
No picture from EXT1 appears on EXT2-
connected monitor.
Note: Normally, if the screen during display is 
sent to EXT2, no picture is sent to EXT2.

SCART2:
No picture from EXT3 appears on EXT2-
connected monitor.

Is video signal 
sent to pin (19) of 
SCART1 (J1101)?

Check SCART1, 
external 
connection or input 
setting.

Is video signal 
sent to pin (40) of 
SCART2 (J1101)?

Check SCART2, 
external 
connection or input 
setting.

Is video signal 
sent to pin (40) of 
SCART2 (J1101)?

Check SCART2, 
external 
connection or input 
setting.

Checklist:
1) Are input terminal on back of TV and "INPUT SOURCE" button        on the remote control set up correctly? ··· See the operation manual and set    
    "INPUT SOURCE" appropriately.
2) Is the Signal Type (item) in MENU-Option-Input Select set to the same as that of the external device? ··· Set it to "CVBS", "Y/C" or "RGB".
3) Is ANT-CABLE disconnected or connected improperly? ··· Connect it correctly as per the operation manual.
4) The picture is sent to the monitor in a CVBS signal if the source during display is TV, CVBS or Y/C of EXT1-3. When sent by component, etc., that 
    signal is not sent to the monitor.
5) When the monitor picture is not sent and is not displayed on the monitor, refer to “No picture” for each terminal.
6) The video output from EXT1 is not the monitor output (output of the picture now watching). The picture of the last selected TV channel is always sent to 
    EXT1. (Specification)
