No picture appears on EXT1 - connected monitor during the tuner (DTV) reception.
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) 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 TV, CVBS or Y/C of EXT1-3.
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 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)
