How Defective Items are Indicated

When the flowcharts lead to a possible cause, this is indicated by a statement giving the name of
the defective part or the cause of the problem, e.g. a defective SPU board is indicated by the
statement "SPU." When there are more possible items, they are listed in order of decreasing
probability.
