7. 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.)
Regarding internal/external synchronization selection of
the image signals by the microprocessor control, the
internal synchronization is selected when the initial display
is provided and when all FL's light up and the external
synchronization at any other time.
Also, except when the initial display is provided, 128
characters for confirmation of the OSD driver are
displayed as the image output.

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.)
