Audio and Video Equipment Technicians generally do the following:
Audio and video equipment technicians install, troubleshoot, and fine-tune sound and picture quality, ensuring that a client’s home entertainment system works at its peak capability. They work on many types of equipment, including customer’s televisions, stereos, satellite dishes, and surround-sound systems. They may specialize in one or many kinds of products. When working on small portable equipment, such as DVD players and video cameras, technicians generally work in central repair shops. When repairing less mobile equipment, such as big-screen televisions, however, they must travel to the customer’s location. If the job is overly complex, technicians may take the equipment back to the shop for further work.
Service technicians’ work involves many different tools. For example, they may use basic hand tools, such as screwdrivers, hammers, and wrenches, to disassemble and reassemble components. They may also use more sophisticated diagnostic tools, including multimeters, voltmeters, oscilloscopes, and digital storage scopes, to identify electronic malfunctions, such as short circuits and failed capacitors. Because of the growing complexity of home entertainment systems, service technicians frequently consult schematics and manufacturers' specifications for instructions on how to repair certain problems.
