I am a student doing a Course in Home Entertainment Systems: Servicing and Repair. I need help in understanding the process of isolation, localisation and removal during Troubleshooting circuits.
I understand the need for using an isolation transformer and its positioning in the event of finding a hot chassis.I am also aware that a stage by stage approach is wanted. How would I isolate a faulty component -a shot resistor- from the circuit or a nonoperational part of a circuit from the rest?
What is the essential difference between "localisation" and "isolation"?
If one localizes a faulty area is that not isolating it from the rest?
