What is component level troubleshooting?

Component level troubleshooting is the process of diagnosing and repairing faults at the individual electronic component level, such as resistors, capacitors, transistors, or integrated circuits, rather than replacing entire boards or assemblies. This skill requires a deep understanding of electronic circuits, the ability to read schematics, and proficiency with test equipment like multimeters and oscilloscopes. It is commonly used in industries where cost savings, sustainability, or lack of spare parts make repairing individual components more practical than replacing larger modules.
