Segment conditions of the FL driver and the FL tube are
checked by turning ON and OFF all segments. Next,
the operation of the FL driver is checked by using the
dimmer control. Then a short between segments next
to each other is checked by turning ON and OFF all
segments alternately (in lattice). (In the above example,
the segments in the second row from the top are
shorted.)
9. EFFECT OFF / DISPLAY CHECK
This program is used to check the FL display section.
The display condition varies as shown below according
to the sub-menu operation. The signals are processed
using EFFECT OFF (The L/R signal is output using
ANALOG MAIN BYPASS.)
The video signal internal/external synchronization
switching is controlled by the microprocessor. When
the initial message is displayed and all the FL segments
light up, it is switched to the internal synchronization but
other than that it is forced to the external
synchronization setting.
Also, except for the initial display, 128 pictographs for
checking the OSD driver are used for the video signal
output display.
