FAULT FINDING

In case of semiconductor circuits, it is deemed that there are few cases in which
the used semiconductor devices have inferior quality or performance deterioration
except due to insufficient design or inspection or by other external and artificial
causes. In general, the relatively many causes are disconnection in a high-value
resistor due to moisture, a defective variable resistor and poor contact of a switch
or relay.
Some troubles are caused by defective parts, imperfect adjustment (such as tuning
adjustment) or insufficient service (such as poor cable contact). It will also be
effective to check and readjust these points.
