TROUBLESHOOTING DETAILS
2.3.1.
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 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 nor 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 2.3.3.1. SIMPLE CHECK LIST(P.32). Difficult problems may
be hard to determine, so repeated testing is necessary.
