(2)Flashing timing table
When an abnormality has occurred for a power supply line, the protection circuit (power supply protector/detection of abnormal
high voltage) operate and cuts the power supply. At this time, the defective line can be identified by the number of flashes (red) of
the "Power supply/function standby/video reception" indication at the front of the unit by means of the fault line which has oper-
ated the protection circuit.
