摘要

Forming a diagnosis of a fault in a consumer electronics product is a many-faceted process. The technician evaluates the complaint of the product's owner, then observes the operation of the set to develop a general idea of the nature of the problem. Only then, generally, does the technician take the back off the unit and begin to check inside. Even now, the technician rarely begins taking measurements. This is the point at which he observes the circuitry. Are there any burned components? Are any circuit traces shorted, cracked, or burned? Are there any traces of overheating? Did the high voltage come up? Are there any strange odors?
