Troubleshooting is for recovering quality and reliability by determining the broken component and
replacing, adjusting or cleaning it as required. First, determine the problem then decide the
troubleshooting method. If you have difficulty findingthe broken part, determine which board is
broken. (For example: the Digital PCB, Analog PCB, etc.) The claim tag from a customer or dealer
may use different expressions for the same problem, as they are not a technician or engineer. Using
your experience,test the problem area corresponding to the claim. Also, returns from a customer or
dealer often have a claim tag. For these cases as well, you need to determine the problem. Test the
unit using the simple check list on
SIMPLE CHECK LIST (). Difficult problems may be hard to
determine, so repeated testing is necessary.
