This program is used to check lighting of the FL display which changes as shown below according to operation of
the sub-menu.
The signals are processed using EFFECT OFF. (The L/R signals are output using ANALOG MAIN BYPASS set-
ting.)
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 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 (monitor screen).
Segment conditions of the FL driver (IC901, IC902) 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 a lattice). (In the above
example, the segments in the second row from the top are shorted.)
