							6.5. TROUBLESHOOTING DETAILS
6.5.1. OUT LINE
Trouble shootin g is for recovering quality and reliabili ty by determining the broken component and replacin g, adjusting or cleanin g
it as required. First, determine the problem then decide the troubleshootin g method. If you have difficult y 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 differen t 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 onSIMPLE CHECK LIST(P.87). Difficul t problem s may be hard
to determine, so repeated testing is necessary.
6.5.2. STARTING TROUBLESHOOTING
Determine the symptom and the troubleshooting method.
