Practical TV/Video Systems Repair is a comprehensive book for electronic repair technicians who want to enhance their understanding of theoretical design and practical service techniques for video electronics such as TVs, VCRs, satellite TV receivers and other video devices. The book uses an input-process-output model to discuss the details of electronic circuitry. This approach creates a higher level of understanding by consistently linking theory, application and troubleshooting. As such, the entire book, as well as each individual chapter, moves from basic theories to practical applications to troubleshooting techniques. Providing users with a tool to enhance their value as employees, each chapter outlines objectives, discusses theory and practice, and arranges learning checks in the form of review questions. Service calls, test equipment primers, end-of-chapter summaries and detailed manufacturer drawings further enhance its value as a quick and effective field reference.
