12.3. Troubleshooting Details
12.3.1. Outline
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 finding the broken part,
determine which board is broken. (For example: the Main PCB, Sensor 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(P.96). Difficult problems may be hard to
determine, so repeated testing is necessary.
12.3.2. Starting Troubleshooting
Determine the symptom and the troubleshooting method.
