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, all segments are alternately turned ON and
OFF (in lattice) to check for any shorts. (In the above
example, the segments in the second row from the top are
shorted.)
