Segment conditions of the FL driver (IC502) 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).
