Repairing Consumer Electronics Without a Schematic

The need to troubleshoot and repair consumer electronics without a schematic occurs every day in the life of a busy electronics technician. The technician who repairs all types of electronic equipment must make quick and practical repairs; otherwise,

lie or she will be out of the business within a few years. It is difficult to have every schematic of the electronic product that appears upon the service bench. Remember, these technicians turn out hundreds of electronic repairs each week, month after month, without a schematic. Even the largest and best-equipped establishment cannot

have all the schematics required to service every piece of equipment that crosses the service bench. The more experienced and better informed the electronics technician is, the more productive in troubleshooting and repairing consumer electronics he or she will be. 

Of course, repairing certain types of electronic products cannot be accomplished unless a certain schematic is available. There are many repairs you can make without a circuit diagram. The tough dog and intermittent service problem are difficult to find without a schematic.

Most repair centers cannot afford every schematic on consumer equipment. Others simply do not have room for them. In addition, some schematics for import models are difficult to obtain. It might take weeks or months to get them, and the electronic product sits for days, in pieces, until the diagram arrives. Sometimes the schematic never

comes; they are no longer available.

Troubleshooting and Repairing Consumer Electronics Without a Schematic begins with servicing methods. These include locating, testing and finally repairing the electronic product. Often, none of these steps can be done without the proper equipment and components.
